1 Before Repair

These equipments (SL-HDS10/310),which are the components
of these systems, are supplied with power from the amplifiers
(SE-HD510/310) through the tuners (ST-HD510/310). When
repairing these equipments or checking operation of the
systems, be sure to connect the amplifiers and tuners with it.

7 Measurements and Adjustments

Cautions:

- It is very dangerous to look at or touch the laser
beam. (Laser radiatlon is Invisible.) With the unit
turned "ON" , laser radiation is emitted from the
pickup lens.

- Avoid exposure to the laser beam, especially when
performing adjustments.

These units SL-HD510/310 are designed to operate on
power supplied from the Amplifiers SE-HDSiO/310 through
the Tuners ST-HD510/310.When connecting the unit to
other system components, do not connect to the Amplifiers
SE-HD510/310 directly. Be sure to connect these units
through the Tuner ST-HD510/310.When operating the units
SL-HD510/310 alone for testing and servicing, without
having power supplied from the Amplifiers SE-HDSiO/Sio,
use the following method,

JK401

7.1. Power Supply to This Unit

alone

Apply 10V DC power to the section between TP402 (far side
from rear panel of R441) and earth plate (E401). (As shown in
Fig. 3.)

7.2. To Check Signals

Connect the oscilloscope or the speaker with built-in amplifier
to the section between JK401-®pin (Rch out) and earth plate
(E401) (GND) as well as the section between JK401-® pin
(Lch out) and earth plate (E401) (GND) and check if the signals
are outputting from this unit. (As shown in Fig. 3.)
