3.7.6.1 Operating The RTU-292C From The Front Panel Keypad
The RTU-292C can be operated from its front panel to allow the unit to be programmed, and if
so equipped, control a Motorola URC-200 radio. When using the front panel, the operator uses
the handset and keypad.
To begin front panel operation the user must enter three "*" key presses. The RTU-292C will
respond with an Acknowledge tone prompt and the voice prompt "
READY ". At this point all
front panel keypad entries are treated just as though the user were sending commands via the
telephone.
Front panel control operation will continue until one of the following conditions occurs:
•
The user enters a "*#" sequence.
•
There is neither PTT activity nor keypad activity for the duration of the activity timer.
While the operator is using the keypad to control the RTU-292C, the unit will not be available
for:
•
PSTN Auto Answering.
•
Radio Squelch Break Access (S/W option).
•
Radio DTMF Control (S/W option).
