If the "Fire B" button is pressed while "Fire A / Enable B" is also pressed,
the "A command" is transmitted, resulting in the firing of the next
sequential receiver output. The output remains on until at least one of the
buttons is released.
1.4.2 Normal Command Mode (digital switch positions C – F)
In this mode the transmitter is idle while no buttons are pressed.
Continuous transmission occurs while "Fire A" or "Fire B" is pressed.
Output firing pulses are stretched to a minimum duration of 0.6 seconds
in the receivers to ensure that cues fire reliably, even when the fire
buttons are pressed for a shorter period of time. Note that it is not
necessary to wait for the completion of the 0.6 second firing pulse period
before firing subsequent cues. They can be fired as fast as the operator
can press the button, provided that each button depression lasts at least
0.1 second, followed by at least 0.1 second with the button released. If
many transmitters are transmitting simultaneously, it may be necessary to
depress a fire button slightly longer than 0.2 second in order to ensure an
output from the receiver.

THE TRANSMIT INDICATOR.
This is a high intensity red indicator, visible in direct sunlight, that lights
continuously while the transmitter is generating RF output. It is located between
the two buttons. It will light even if the battery voltage is below the low battery
detect threshold. It can be used to check microphone sensitivity by indicating
acoustic event detection in acoustic mode with the receiver(s) switched off. "Fire
A / Enable B" must be depressed while conducting this check. Adequate
microphone sensitivity can be verified by observing a red flash each time an
event is detected. This is a useful tool for setting microphone sensitivity with the
digital switch. (See section 1.7)
1.6
THE BATTERY.
Power is supplied from an alkaline 9 volt battery, accessible beneath a slide-out
door on the back side of the transmitter. This battery should be replaced when
required by conditions described in section 1.3 above. In order to prevent the
possibility of damage due to battery leakage, the battery should always be
removed if the transmitter is to be stored for a prolonged period. Damage due to
battery leakage is not covered under the warranty.
