[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).
