| Step | Condition | Adjustment | Procedure |
|---|---|---|---|
| 1 | USB No Mod. | Remove the PCB between TP101, TP102 and TP103 from Main PCB. Connect a DC AM Meter to TP (+) and TP (-). Adjust DRIVER for 50 mA reading on the DC AM Meter. | |
| 2 | USB No Mod. | Remove the PCB between TP101, TP102 and TP103 from Main PCB. Connect the DC AM Meter to TP (+) and TP (-). Adjust FINALE for 50 mA reading on the DC AM Meter | |
| 3 | USB 1 mV Mod. | Connect a RF Power Meter to Ant.jack. Connect a RF VTVM, an Oscilloscope and an RF Linear Dectector across an Dummy Load to the RF Power meter. Adjust for maximum reading en the RF VTVM. During this step, set the AF Oscillator so that the output is less than 20 V. Repeat this step two times. | |
| 4 | USB 30 mV Mod. | Adjust XXX for 32.5 V reading on the RF VTVM. | |
| 5 | USB 30 mV Mod. | Adjust MOD Bal so that the carrier leakage at USB and LSB become minimum and almost equal. | |
| 6 | CW No Mod. | Connect a SW between Pin 8 and 9 of ACC connector. When turn on the SW, adjust for 21 Watt reading on the RF Power Meter. | |
| 7 | AM No Mod. | Adjust CW PWR for 10 Watt reading on the RF Power Meter | |
| 8 | AM No Mod. | S-METER | Adjust S-METER so that "9" LCD just light on. |
| 9 | AM 1 kHz 30 mV Mod. | AM MOD | Adjust AM MOD to obtain the 85% negative reading on the Oscilloscope. |
| 10 | AM 1 kHz 1 mV Mod. | RF METER | INDIC: MOD. Adjust RF METER so that "9" LCD just light on. |
| 11 | FM 1 kHz 30 mV Mod. | FM DEV | Adjust for +/- 3 kHz deviation on the FM Linear Detector. |
| 12 | CW No Mod. Vol.: Max. | CW PWR | Connect an AF VTVM across a Dummy Load (8 ohm) between Pin 1 and Pin 2 of ACC connector. When turn on the SW, adjust CW PWR for 0.4 V reading on the AF VTVM. |

| 1 | AM SSG 40dB 1 kHz Mod. | Alignment of sensitivity. Adjust coils for maximum reading on the AF VTVM. | |
| 2 | AM SSG 66dB 1 kHz Mod. | Alignment of Squelch. Set Squelsch to maximum. Adjust VR102 so that the squelch just breaks. | |
| 3 | AM SSG 46dB No Mod. | Alignment of S-meter. Adjust so that "9" LCD just lights on. | |
| 4 | FM SSG 1 mV 1.5 kHz Dev. | Adjust for maximum reading on the AF VTVM. | |
| 5 | AM SSG 1 mV Noise Gen. | Adjust for maximum reading on the AF VTVM. Noise Generator output: 50 Hz SQ wave 2 V P-P. | |
