Hidden Menu procedures.
SQL and S-Meter Adjustments
1) Turn the receiver off.
2) Press and hold [F] and [SCAN] keys; while holding them in, press and hold the [PWR] switch until the radio powers on. You are now in the alignment mode.
3) Set the receiver to 145.10000 MHz, with 100 kHz frequency steps.
4) Connect the RF Signal Generator to the antenna jack.
5) Press the [M/S] button to select the main VFO which should be tuned to 145.10000.
FM-N Mode Squelch Level Adjustment (Main Band)
1) Set the receiver to the FM-N mode.
2) Press the [SCAN] button to select “Set M-SQL THRESH (FM)”.
3) Tune the signal generator to the same as the radio with +/- 3.5 kHz deviation @ 1 kHz tone modulation, and set the output level for –5dBu at the antenna jack, then press the [ENT] button.
4) Press the [SCAN] button to select “Set M-SQL TIGHT (FM)”.
5) Tune the signal generator to same frequency as radio with +/- 3.5 kHz deviation @ 1kHz tone modulation, and set the output level for +10 dBu, then press the [ENT] button.
AM Mode Squelch Level Adjustment (Main Band)
1) Set the receiver to AM mode.
2) Press the [SCAN] button to select “Set M-S THRESH (AM)”.
3) Tune the signal generator to the same as the receiver with 400 Hz tone modulation, and set the output level for –5 dBu then press the [ENT] button.
4) Press the [SCAN] button to select “Set M-S TIGHT (AM)”.
5) Tune the SG to the same as radio with 400 Hz tone modulation and set the output for +10dBu then press the [ENT] button.
FM-N Mode S-Meter Adjustment (Main Band)
1) Set the rcvr to the FM-N mode.
2) Press the [SCAN] button to select “Set MAIN S-METER 1”.
3) Tune the SG to the same as radio with +/- 3.5 kHz deviation @ 1 kHz tone modulation and set the output level for –5 dBu the press the [ENT] button.
4) Set the radio to the AM mode.
5) Press the [SCAN] button to select “Set MAIN-S METER 5”.
6) Tune the SG to the same as radio with 400 Hz tone modulation and set the output level to +20 dBu then press the [ENT] button.
FM-W Mode Squelch Level Adjustment (Main Band)
1) Set the radio to WFM mode.
2) Press the [SCAN] button to select “Set M-S THRESH (WFM)”.
3) Tune the SG to the same as radio with +/-22.5 kHz deviation @ 1kHz tone modulation and set the output level to +5 dBu then press the [ENT] button.
4) Press the [SCAN] button to select “Set M-S TIGHT (WFM)”.
5) Tune the SG to the same as radio with +/-22.5 kHz deviation @ 1kHz tone modulation and set the output level for +15 dBu then press the [ENT] button.
FM-W Mode S-Meter Adjustment (Main Band)
1) Set the radio to the WFM mode.
2) Press the [SCAN] button to select “Set M.S-METER 1 (WFM)”.
3) Tune the SG to the same as radio with +/-22.5 kHz deviation @ 1 kHz tone modulation and set the output level for +8 dBu then press the [ENT] button.
4) Press the [SCAN] button to select “Set M.S-METER 5 (WFM)”.
5) Tune the SG to the same as radio with +/-22.5 kHz deviation @ 1kHz tone modulation and set the output level for +30 dBu and press the [ENT] button.
Press the [M/S] button to select the SUB vfo band
FM-N Mode Squelch Level Adjustment (SUB Band)
1) Set the radio to 145.10000 MHz with 100 kHz steps.
2) Set to FM-N mode.
3) Press the [SCAN] button to select “Set S-SQL THRESH (FM)”.
4) Tune the SG to same as radio with +/-3.5 kHz deviation @ 1 kHz tone modulation and set the output level to –3dBu and press the [ENT] button.
5) Press the [SCAN] button to select “Set S-SQL TIGHT (FM)”.
6) Tune the SQ to the same as radio with +/-3.5kHz deviation @ 1kHz tone modulation and set the output level to +10 dBu then press the [ENT] button.
AM Mode Squelch Level Adjustment (Sub Band)
1) Set the radio to the AM mode.
2) Press the [SCAN] button to select “Set SUB S THRESH (AM)”.
3) Tune the SG to the same as radio with 400 Hz tone modulation and set the output level to –3 dBu then press the [ENT] button.
4) Press the [SCAN] button on the panel to select “Set SUB S TIGHT (AM)”.
5) Tune the SG to same as radio with 400 Hz tone modulation and set the output to +10 dBu then press the [ENT] button.
FM-N Mode S-Meter Adjustment (SUB Band)
