Alignment
CTCSS TX Deviation
1. Tune the frequency to 146.050 MHz, then activate the
CTCSS encoder with a “100 Hz” tone, and set the trans-
mit power level to “LOW.”
2. Press the [ F/W
] key, then press the [
MR
(
SKIP
)] key to
set the alignment parameter to “
A5 CTC.xxx
.”
3. With in five second of appearing the “
A5 CTC.xxx
” on
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).
S-meter Sensitivity
1. Tune the frequency to 146.050 MHz.
2. Inject a 146.050 MHz signal at a level of –5 dBµV (with
1 kHz modulation @±3.5 kHz deviation) from the RF
signal generator.
3. Press the [ F/W
] key, then press the [
MR
(
SKIP
)] key to
set the alignment parameter to “
A6 SM U
/
D
.”
4. With in five second of appearing the “ A6 SM U / D ” on
the display, press the [
(
MHz
)] key.
5. Increase the RF signal generator output level to +23
dBµV.
6. Press the [ F/W
] key to recall the alignment parameter
to “
A6 SM U
/
D
.”
7. With in five second of appearing the “ A6 SM U / D ” on
the display, press the [
(
MHz
)] key.
Squelch Sensitivity
1. Tune the frequency to 146.050 MHz.
2. Inject a 146.050 MHz signal at a level of –12 dBµV (with
1 kHz modulation @±3.5 kHz deviation) from the RF
signal generator.
3. Press the [ F/W
] key, then press the [
MR
(
SKIP
)] key to
set the alignment parameter to “
A7 SQL U
/
D
.”
4. With in five second of appearing the “
A7 SQL U
/
D
” on
the display, press the [
(
MHz
)] key.
5. Increase the RF signal generator output level to –3
dBµV.
6. Press the [ F/W
] key to recall the alignment parameter
to “
A7 SQL U
/
D
.”
7. With in five second of appearing the “
A7 SQL U
/
D
” on
the display, press the [
(
MHz
)] key.
DC Voltmeter
1. Set the power supply voltage to 9.9 V.
2. Press the [
F/W
] key, then press the [
MR
(
SKIP
)] key to
set the alignment parameter to “ A8 BAT RV .”
3. With in five second of appearing the “
A8 BAT RV
” on
the display, press the [ REV
(
HOME
)] key.
To close the alignment mote
, just turn the power
off by rotating the
VOL
knob fully counter clockwise. The next
time the transceiver is turned on, normal operation may resume.
