Panel Test ModeThe transceiver’s transmission output, receiver sensitiv-ity, and other items are measured and QT, DQT, 2-Tone andDTMF signalling is decoded in this mode.2-1. To Enter the Panel Test ModeHold down [PF1] and turn the power switch on to enterthis mode. The test frequency channel and test signallingchannel will be displayed.Test frequency CH Test signalling CHOP B2-2.

Panel Tuning ModeThe transceiver is adjusted in this mode.3-1. To Enter the Panel Tuning ModePress the [PF3] key in the panel test mode.The adjustment items, the frequency and signalling, otherthan the maximum deviation and sensitivity, return to the val-ues that were effective for the test frequency channel andtest signalling channel before entering the panel tuningmode.
