Set 'em the same way as any other device. Send a tone with cop,4 and adjust
(with the RTCM pot) for 3KHz (no P/L) on your service monitor.

for example:
*CLI> rpt cmd <node number> cop 4 <anything>

where <anything> = any string or number (command parser is kinda dumb)

Repeat above command (type up arrow) to stop tone.
