CAUTION WHEN SERVICING

DX-ZS300 do no have a power transformer and recive ther power supplies from the cassettereceiver and
amplifier through a 11—pin flat cable.

If the cassette receiver and available. follow the procedure below.

Connect the Multi—power supply (LPS-9088) in the manner below.

~FL201 does not light as AC power for FL201

is not supplied.

Connection diagram when using multi power supply (LPS—9088).

~Connect to J1 of the LPS—9088 using multiconversion harness.

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

This set employs laser. Therefore. he sure to follow carefully
the instructlons below when servicing‘

WARNING”

WHEN SERVICING, DO NOT APPROACH THE LASER EXIT -
WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY
TO CONFIRM LASER BEAM EMISSION. BE SURE TO
OBSERVE FROM A DISTANCE OF MORE THAN 300m
FROM THE SURFACE OF THE OBJECTIVE LENS ON THE
OPTICAL PICK-UP BLOCK.

l Caution: Invisible laser radiation when
open and interlocks defeated avoid expo—
sure to beam

I Advarsel: Usynlig Iaserstéling ved abning,
nar sikkerhedsaibrydere er ude at tunktlon.
Undga udsaattelse for strallng.
