RTU-292 Operations Manual
3.7.11 OPTIONAL 4 WIRE OPERATION
The unit can be set to operate with a four wire device instead of a standard 2 wire phone. The
additional I/O is handled by header J6 on the main PCB. The STU-III option makes use of this
capability. To put the RTU-292, first place the unit in programming mode with the *99
command. Then enter the * 6 1 DTMF command. To return to 2 wire operation, enter * 6 0.
To query the unit for its current setting, enter * 6 # (requires voice prompt option to hear
response from unit). See Table 3-2. When programming is complete, enter * # to exit the
programming mode.
3.8 FACTORY RESET
It’s possible to perform a Factory Reset that will return all user-programmable parameters
(other than the speed dial directory) to the initial factory default settings. This includes the
system password, the Inactivity Disconnect and Calling Timers, etc.
To perform a Factory Reset, hold the 0 (zero) key in on the front panel keypad while the main
power is turned on. After the unit has powered up, let go of the 0 key.
3.9 SPEED DIAL RESET
A Speed Dial Reset completely erases the information in the speed dial directory.
To perform a Speed Dial Reset, hold the 1 (one) key in on the front panel keypad while the
main power is turned on. After the unit has powered up, let go of the 1 key.
