[T-1] off: Turnsunitoffandperformsbatterytest.
[T-2] on: Ohm-meter / Tone: Turnstheunitonandcyclesthroughthefollowing
commandswhenpressedrepeatedly.
Ohm-meter: Measuresthecontinuityofthetraceconductor/pipeanditsfar-end
ground.Itisalsousedtomeasurethefaultresistancetoearth.
Tone: Inthetonemode,thetransmittergenerates577Hzand200kHzsignals.
[T-3] on: Trace (frequency): TurnstheunitonandplacestheunitinTracemode.
Select Frequency: PressTrace[T-3]repeatedlytocyclethroughthetransmitter’s
activefrequencies(577Hz,8kHz,33kHz,and200kHz).Theselectedfrequency
willbedisplayed[T-4].‘ALL'indicatesthatthefollowingactivefrequenciesare
transmittingsimultaneously:577Hz,8kHz,33kHz,and200kHz.

NOTE: An external 12-volt power source is required to obtain Max Output level (12
watts for 12-watt transmitters and 5 watts for 5-watt transmitters).
