5.5.6. Press the “STATUS” switch. The Controller will request status from all

System Safety Feature Once armed, the Remote Units must be sent a Fire
command within the Arm Time Period. If the Remote Units do not receive a Fire
command within the Arm Time Period, they will automatically disarm. The firing
capacitor will be safely internally discharged, the binding posts will remain isolated from
the firing capacitor and the binding posts will remain shunted together.

ARMED light next to each selected Remote Unit switch will flash for 5 seconds, and
then come on steady for two seconds. ARMED lights for selected Remote Units that
the Controller did not receive a status message from will begin to flash again. The
selected Remote Units are now assumed to be ARMED! For unconfirmed
communications, count to 5 from when the "ARM" switch is pressed and assume the
Remote Units are armed.

an indication of shot initiation. The ARMED light will go out and the green SAFE light

initiate the remaining shots.

and press the “DISARM” switch. All selected Remote Units will disarm in
approximately 3 seconds.
