3.0 Programming Procedures
3.1 Programming the RM-20
Programming procedures
The model RM-20 can be easily programmed locally with a standard DTMF telephone. Programming can also be
achieved “over the air” with a DTMF microphone.
Note: Programming over the air requires a program access code. This code must be programmed locally on initial
installation.
Local programming
Local programming is accessed by plugging a DTMF telephone handset into the programming jack (J1) on the rear
panel of the RM-20. To access the local program mode, turn the power off and back on and press the * (asterisk)
key within two seconds of applying power to the unit. The RM-20 will generate a series of beeps to the
programming telephone earpiece acknowledging the program mode entry. An easy way to insure that the * is
received within 2 seconds is to have the * key pressed as power is applied, then release it as soon as the tone is
heard.
Over the Air programming
The model RM-20 can also be programmed over the air using a DTMF microphone or a portable radio equipped
with DTMF keypad. However an “over the air” program code (up to 9 digits) must be programmed into the unit. It
is suggested that this code is programmed on initial installation. Once an “over the air” programming code is
programmed, the RM-20 can be easily accessed and programmed over the air. Simply send the access code
accompanied by carrier and monitor the transmitter frequency. If successfully entered in the program mode a series
of beeps will be heard. Proceed to enter the program codes needed to be programmed by pressing each key slowly
and firmly and monitor the frequency for the acknowledge tones. The programming code entry sequence is exactly
the same as in local programming mode. Once the unit is programmed, press (00#) to exit the program mode.
To assist the programming process, a number of confidence toned will heard. They are:
Valid parameter beep One 1 KHz tone (e.g. 1#)
Code accepted Five 1 KHz tones (e.g. 1#0#)
Error beep Three 400 Hz tones (e.g. 80#)
