4 Channel and Tone Frequency Programming

Channel and tone frequency programming is most easily accomplished with RF

Technology TecHelp / Service Monitor 2000 software. This software can be run on an

IBM compatible PC and provides a number of additional useful facilities. DOS and

32-bit versions are available.

TecHelp / Service Monitor 2000 allows setting of the adaptive noise squelch threshold,

provides a simple means of calibrating the forward and reverse power detectors,

setting the power alarm preset levels, and enabling transmitter hang time and timeout

time limits. TecHelp / Service Monitor 2000 can be supplied by your dealer,

distributor or by contacting RF Technology directly.
