SECTION 1

GENERAL

ATT (attenuator) selector

If a loud sound is distorted when the transmitter
is connected to an audio output jack other than
the headphones jack, set the ATT selector on the
transmitter to -12 dB. The default setting of the
ATT selector is 0 dB.

Flexible Circuit Board Repairing

• Keep the temperature of soldering iron around 270˚C
during repairing.

• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering
or unsoldering.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

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.
