NOTES FOR ICRI-2P CONFIGURATION DRAWING:
INPUT BLOCKING TIME JUMPERS:
With jumpers "on,” the ICRI will respond to a new voice signal approximately 0.8 seconds after
the last transmission has ended. This is the standard configuration. With the jumper removed,
this time is extended to approximately 2 seconds. During this time, no new PTT can be initiated
by any input except the handset. JP1: PORT 1, JP2: PORT 2.
TIME OUT TIMER DEFEAT:
With this jumper "off,” the telephone or radio input channel will be temporarily disabled after a
timed period of continuous activity. The timing range is approximately 30 seconds to 2 minutes,
as set by time out timer adjust controls. If the input signal is removed for approximately 5
seconds, the time out timer resets and operation returns to normal. Installation of defeat jumper
turns off the time out timer and the channel will never be disabled.
HANDSET CIRCUIT POWER CONTROL:
If the handset circuit will not be used, JP12 can be removed to turn off power to the circuit and
extend battery life.
AUDIO BUFFER DELAY CIRCUIT POWER CONTROL:
If the audio delay will not be used, JP5 can be removed to extend battery life.
