| Step | Condition | Adjustment | Procedure |
|---|---|---|---|
| 1 | CH: 19, BAND: MID VOL: Max. SQ: Min. MODE: AM | L7, L6 L5, L4 L1 | Connect RF SSG to Ant. jack and AC Voltmeter to Ext. Speacer. Then adjust coils for maximum reading on AC Voltmeter. |
| 2 | VOL: Max. SQ: Min. MODE: AM | L2 L3 | Adjust L2 for maximum output of noise level in LOW BAND CH 1. Then adjust L3 by same way of adjustment for L2 in HIGH BAND CH 40. Ant then adjust L2 by turn CW in LOW BAND CH 1 so that the same noise level of adjustment for L3. |
| 3 | CH: 19, BAND: MID VOL: Max. SQ: Max. MODE: AM | VR2 | Set the output level of RF SSG to 1000uV. Adjust VR2 for 2 V output reading on AC Voltmeter. |
| 4 | CH: 19, BAND: MID VOL: Max. SQ: Min. MODE: AM | VR1 | Set the output level of RF SSG to 100uV. Adjust VR1 so that the needle of built-in signal meter point "S-9". |
| 5 | CH: 19, BAND: MID VOL: Max. SQ: Min. MODE: FM | L801 | Adjus VOL to obtain 2 V output on AC Voltmeter. Set the level of RF SSG to 100uV. Adjust L801 for maximum reading on AC Voltmeter. |

| MIC GAIN | Max. |
| Step | Condition | Adjustment | Procedure |
|---|---|---|---|
| 1 | CH: 19 BAND: MID POWER: Max. AM, No Mod. | L19 L20 L18 | At first, turn down the coar of L18 to end. Connect Oscilloscope to TP2 (lead of R79). Adjust coils for maximum reading on Oscilloscope |
| 2 | CH: 19, BAND: MID POWER: Max. AM, No Mod. | L20 L15 L14 | Connect RF Power meter to Antenna jack. Adjust coils for maximum reading on RF Power Meter. |
| 3 | CH: 1, BAND: LOW CH: 40, BAND: HIGH POWER: Max. AM, No Mod. | L11 | Adjust L11 for minimum difference between the follow conditions of the set: CH: 1, BAND: LOW CH: 40, BAND: HIGH |
| 4 | CH: 19 BAND: MID POWER: Max. AM, No Mod. | VR3 | Adjust VR3 so that the needle of built-in TX Power Meter point Brank sone of "Sig. 9" |
| 5 | CH: 19 BAND: MID POWER: Min. AM, No Mod. | VR501 | Adjust VR501 so that the RF output power level is over 1.5 V and under 4.0 V in every channel. |
| 6 | CH: 1 BAND: MID POWER: Max. FM | VR801 | Connect Deviation Meter to Ant. jack and AF Oscillator to Mic jack. Set AF Oscillator to 30 mV output. Adjust VR801 for 4 kHz deviation. |
| 7 | CH: 19 BAND: MID POWER: Max. AM, No Mod. | VC1 | Connect Frequency Counter to Ant. jack. Adjust VC1 for 27.185000 +/- 20 Hz on Frequency Counter. |
