Good manual. It is complete and of high quality, both text and graphics. The schematics are with the original big size, so it can be viewed or printed without any loss of resulution and sharpness.
SECTION 3 ELECTRICAL ADJUSTMENTS
Note : 1. The adjustments should be performed in the order given. (As a general rule the transmitter section (TMR-IF630R) adjustments should be completed before performing the headphones section (MDR-IF630R) adjustment.) 2. The adjustments and measurements should be performed for both L-ch and R-ch unless otherwise indicated. 3. L-ch adjustment should be completed before performing R-ch adjustment. 4. Supply 9 V dc to the transmitter section (TMR-IF630R) and 2.4 V dc to the headphones section (MDR-IF630R) as the power voltage. TRANSMITTER SECTION [ OSCILLATING FREQUENCY ADJUSTMENT ] Connection :
Frequency counter TX BASE board TP11 iL-ch j TP13 iR-ch j
[ RF LEVEL ADJUSTMENT ] Connection :
RF voltmeter TX BASE board TP11 (L-ch) TP13 (R-ch) TP15 (GND)

Adjustment Procedure : No signal state. 1. Connect the RF voltmeter to TP11 (L-ch) and TP13 (R-ch) on the TX BASE board. 2. Adjust with RV51 (L-ch) and RV1 (R-ch) on the TX BASE board so that the reading on the RF voltmeter becomes the specified value. Specified Value : L-ch R-ch RV51 RV1 480 mV ± 2.5 mV 480 mV ± 2.5 mV
