MANUALS / OPERATING INSTRUCTIONS

AST-321 OPERATING MANUAL


1. GETTING STARTED

• Remove the four screws attaching the top to the plastic housing.
• Carefully remove the top cover.
• Insert two AA size batteries in the holder.

ATTENTION! Be careful when inserting or replacing the batteries. Pay great attention to appropriate polarity. Irreversible damage may be done by inserting the batteries with wrong polarity. Pay attention to the "+" and "-" signs.

• Put the cover back and fasten the screws.

2. TURNING THE DEVICE ON AND OFF

• Turning on: press the two buttons at the same time and keep them pressed for approximately 5 seconds. The welcome screen appears.



Immediately after the welcome screen, the countdown screen appears, showing the last value that has been set.



Now the device is in stand-by mode, where you have 3 options. You can

1) start the countdown (activate the "bomb"),
2) go to programming mode or
3) turn the device off.

• Turning off: start pressing either of the buttons and a little later press the other one and keep them both pressed for a few seconds.

NOTE: After the device has been set to stand-by mode, it remains in this state for 60 minutes, then turns off (goes to sleep mode).

NOTE: In stand-by mode, regardless to the economy function setting, the screen will go blank after 15 seconds, but it can be brough back by pressing either of the buttons.

3. STARTING THE COUNTDOWN (ACTIVATING)

• Set the device to stand-by mode.
• Press the left button and keep it pressed until the countdown begins. While pressing the button, the following screen will appear:



After successful (uninterrupted) activating, the countdown begins.

NOTE: If the economy function is turned on, the numbers indicating countdown disappear from the screen after 15 seconds and only the two dots blink every second.



NOTE: By default, countdown is accompanied by a beep sound every second. You can turn this function off in programming mode.

4. STOPPING THE COUNTDOWN (DEFUSING) (only for game modes when defusing is done using the button)

• Press the left button and keep it pressed until the countdown stops. You will have to keep the button pressed for as long as what value has been set in programming mode. While pressing the button, the following screen will appear:



If defusing time has been set to more than 5 seconds, after the text "defusing" has scrolled, the screen will switch to countdown (showing how much more you have to keep the button pressed to defuse the device).



NOTE: If defusing is interrupted, you will have to start it all over again.

If you have been successful, the following screen appears (and the device start beeping twice at a time):



• Press either of the buttons and keep it pressed for 5 seconds to go back to stand-by mode.

If you fail to stop the countdown (defuse the "bomb") in time, it will go off ("explode"). This is indicated by rapid beeping and the following screen:



After the "bomb" has gone off, the device remains in this state for 60 minutes more, then turns off.

• Press either of the buttons and keep it pressed for 5 seconds to go back to stand-by mode.

5. PROGRAMMING MODE

• Set the device to stand-by mode.
• Press the right button and keep it pressed until you enter programming mode. While pressing the button, the following screen will appear:



5.1. Setting countdown time



• Press the left button to set the desired value. You can set the countdown time between 1 and 99 minutes with the following increments:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 and 99.

NOTE: If you press the left button and keep it pressed, the possible values will start rolling in the above order.

• Press the right button to finish setting the countdown time. (The menu jumps to the next setting option.)

5.2. Setting defusing time



• Press the left button to set the desired value. You can set the defusing time between 5 and 30 seconds with the following increments:

5, 7, 10, 12, 15, 20, 25 and 30.

NOTE: If you press the left button and keep it pressed, the possible values will start rolling in the above order.

• Press the right button to finish setting the defusing time. (The menu jumps to the next setting option.)

5.3. Setting the game mode

Here you can choose whether the device should be able to be defused using the (left) button only or using the three wires only or either way. By default, you can see the following screen (indicating that both defusing methods work currently):



• Press the left button to disable defusing using the (left) button. With this setting, the device can only be defused by the wires.



• Press the left button to disable defusing using the wires. With this setting, the device can only be defused by the (left) button.



How the wires work:

When you use the wires for defusing, there is always a chance that the device will go off ("explode") as the function of each of the three wires randomly changes every time a new game (countdown) is started. One of the wires makes the device go off ("explode"), the other one stops the countdown (defuses the "bomb"), while the third one makes the countdown twice as fast.

NOTE: It does not matter which wire you plug in which socket. The randomly changing function is in connection with the socket, not the wire that is plugged in it.

ATTENTION! Do not cut the wires. They only need to be disconnected.

Game modes:

#1 + key switch in green position (keys not in use)

The device can be activated and defused using the (left) button by anyone.

#2 + key switch in zero (red) position

The device can only be activated and defused using the (left) button by the players who have the key.

#3 + key switch in green position (keys not in use)

The device can be activated using the (left) button by anyone but can only be defused using the wires.

#4 + key switch in zero (red) position

The device can only be activated by the player who has the key and can be defused using the wires by anyone or using the (left) button by the player from the other team who has the key. (You can also start the game in a way that the key is in the switch so that any member of the "bombing" team can activate the device but, after activating the "bomb", the key is removed.)

NOTE: In this setting menu, when the wire option is turned on, you can check if the wires are connected properly because if any of the wires is disconnected, the sign on the left side of the screen changes (the lower segment indicating the wire is switched to the upper one, see figure below). This may be helpful during troubleshooting.



• Press the right button to finish setting the game mode. (The menu jumps to the next setting option.)

5.4. Setting the sounds

• Press the left button to select between the sound options. You have the following options:

beep turned on upon "explosion", after defusing and during countdown

beep turned off completely

beep turned on during countdown

beep turned on after defusing

beep turned on after defusing and during countdown

beep turned on upon "explosion" (timer mode)

beep turned on upon "explosion" and during countdown

beep turned on upon "explosion" and after defusing

• Press the right button to finish setting the sounds. (The menu jumps to the next setting option.)

5.5. Setting the display

There are two features you can set here. You can decide whether you want the random number of the game mode when using the wires to appear on the screen (this is indicated by "r") and you can turn the economy function on or off. (The only purpose of the random number being shown is that you can be certain that the function of the wires does change randomly.) Economy function means that, in order to save battery power, the screen goes blank after 15 seconds during countdown, but the numbers can temporarily be brought back if you press either of the buttons.

By default, you can see the following screen (meaning that the order of the wires will appear on the screen and economy is turned off):



• Press the left button to turn the display of the order of the wires off and economy on.



• Press the left button to turn display of the order of the wires off and economy off.



• Press the left button to turn the display of the order of the wires on and economy on.



NOTE: If the screen reads "d", the economy function is turned off, while if the screen reads "_" (where the "d" should be displayed), the economy function is turned on.

Displaying the order of the wires:

When the display of the order of the wires is turned on (indicated by "r" in the settings above) and you are playing a game mode in which defusing by wires is enabled, the order of the wires (their current function) is displayed after the "activating" text appearing on the screen during activation. This feature is partly present so that you can tell that the order of the wires does change over and over again when starting a new game.

The three wires can have the following functions:

meaning defusing

meaning "explosion"

meaning faster countdown

Thus, when (for instance) appears after the text "activating", you can tell that the left wire will defuse the device, the middle one will make it go off ("explode"), while the right one will make the pace of countdown twice as fast.

• Press the right button to finish setting the economy function. The device goes back to stand-by mode.

NOTE: In programming mode, if neither of the buttons is pressed for 1 minute, the device will turn off (go to sleep mode) in order to save battery power. This is normal operation of the device. If this happens, changes in the software that might have been made after entering the programming mode will not be saved.

6. MEASURING BATTERY VOLTAGE

• Set the device to stand-by mode.
• Press the right button once.

(indicating 2.4 volts)

NOTE: The device can be operated safely as long as the voltage is higher than 2.3 volts.

• Press the left button to go back to stand-by mode.

7. USING THE KEY SWITCH

The key switch performs a very simple task: it physically disables the controlling buttons when set to zero (red) position. By using it, you have an extra game mode. The point is that only two players (one from each team) get one of the keys and, therefore, only they can access the device. This way, only one player can activate the "bomb" and only one can defuse it, making the game more difficult for both teams beacuse the team members need to protect the player who has the key, otherwise there will be no-one to activate or defuse the device.

This is how you should use the keys:

(activating player:) Activate the device, then turn the switch to zero (red) position so that no-one can access the controls without a key.

(defusing player with the key:) Turn the switch to green position, then defuse the "bomb".

(defusing player without the key:) Pull one of the wires -- and pray it is not the one that makes the device go off. :)*

* only in game modes where defusing by wires is turned on (see the Features overview on game modes)

ATTENTION! Take good care of the two keys because we cannot guarantee to give you another pair if you lose one or both of them. Also, if you lose both keys and the key switch is in zero (red) position, you will not be able to use the device at all unless you alter the configuration.

8. MAINTENANCE

The device needs no particular maintenance. However, it is recommended to pay attention to the batteries and replace them if necessary.

9. TROUBLESHOOTING

If you should experience something extraordinary compared to what is written above, first, you should try disconnecting the batteries (unplugging the wire of the battery holder) or, if it still does not work, short-circuit the pins of the battery connector on the mainboard (PCB) to reset the device. Also, make sure that the batteries you are using have not been depleted. (Replace them if necessary.)

If you cannot turn the device on and have tried the two methods mentioned, check if the connections at the bottom side of the buttons are appropriate. If they seem ruined (for any reason), ask a professional for help in repairing them. Some welding may be necessary. (Reparing the connections at the buttons will NOT void the warranty.)

If you happen to face a kind of problem that does not seem to be able to be solved by the above, contact us at support@mofra.eu.
