DR1x Squelch Alignment Procedure

DR1x Squelch Alignment Procedure

Internal System Alignment Routine
This uses a programmed routine in the transceiver which simplifies many previously complex discrete component settings and adjustments with digitally-controlled settings via Microphone buttons.
To enter the Alignment mode: Connect the PANEL-UNIT to TX-MAIN-UNIT and RX-MAIN-UNIT.
Press and hold in the [D(X)] and [DISP)] keys while turning the transceiver on.
The transceiver is now in the "Transceiver mode".
Press and hold in the [POWER(LOCK)] key for two seconds.
Press and hold in the [F(MW)] and [GM)] keys while turning the transceiver on.
Press the [POWER(LOCK)] key. "LOCK" will appear in the display.
Press the keys of the Microphone in the following sequence.
[0] . [3] . [4] . [0] . [3] . [4]
Press the [POWER(LOCK)] key.  "UNLOCK" will appear in the display.
The transceiver is now in the "Alignment mode".

Squelch Threshold Level
1. Set the RF signal generator to 440.050 MHz. Set the generator for ±3.5 kHz deviation of a 1 kHz modulation tone, and set the RF output level from the signal generator to -10 dBμV.
2. Set the RX-MAIN-UNIT frequency to 440.050 MHz.
3. Press the [D(X)] key to select "FM".
4. Press the [P1] key of the Microphone to set the alignment menu Item to "Adj 09 SQL/A".
5. Press the [P4] key to save the new setting.
6. Increase the output level of the signal generator up to -3 dBμV.
7. Press the [P3] key to save the new setting.
8. Set the RX-MAIN-UNIT and RF signal generator frequency to 146.050 MHz.
9. Increase the output level of the signal generator up to -10 dBμV.
