Alignment
CTCSS TX Deviation
1. Rotate the DIAL knob to select the display to “B0206,”
then activate the CTCSS encoder with a “100 Hz” tone,
and set the transmit power level to “LOW.”
2. Press the [F/W] key, then press the [MR/MW(SKIP)]
key to set the alignment parameter to “A5 CTC.xxx
A5 CTC.xxx

the display, press the PTT switch to activate the trans-
mitter (with no microphone input), adjust the DIAL
knob so that the deviation meter reading is 0.7 kHz
(±0.05 kHz).

To close the alignment mode
1. Turn the power off by rotating the [VOL/PWR] knob
fully counter clockwise.
2. The next time the transceiver is turned on, press and
hold in the [VFO(PRI)] key turning the radio on. Once
the radio is on, release the key.
normal operation may resume.
