1.1.2 Safety Check after Servicing

Examine the area surrounding the repaired location for damage
or deterioration. Observe that screws, parts and wires have been
returned to original positions, Afterwards, perform the following
tests and confirm the specified values in order to verify compli­ance with safety standards.

(1) Insulation resistance test

Confirm the specified insulation resistance or greater be­tween power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear­phone jacks, etc.).
See table 1 below.

(2) Dielectric strength test

Confirm specified dielectric strength or greater between
power cord plug prongs and exposed accessible parts of
the set (RF terminals, antenna terminals, video and audio
input and output terminals, microphone jacks, earphone
jacks, etc.). See Fig.11 below.

(3) Clearance distance

When replacing primary circuit components, confirm spec­ified clearance distance (d), (d') between soldered termi­nals, and between terminals and surrounding metallic
parts. See Fig.11 below.

(4) Leakage current test

Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed ac­cessible parts (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear­phone jacks, etc.).
Measuring Method : (Power ON)
Insert load Z between earth ground/power cord plug
prongs and externally exposed accessible parts. Use an
AC voltmeter to measure across both terminals of load Z.
See Fig.9 and following Fig12.

SPECIFIC SERVICE INSTRUCTIONS

2.1 BEFORE ASSEMBLY AND DISASSEMBLY

2.1.1 Precautions

1. Be sure to disconnect the power supply unit prior to mount­ing and soldering of parts.

2. Prior to removing a component part that needs to disconnect
its connector(s) and its screw(s), first disconnect the wire(s)
from the connector(s), and then remove the screw(s).

3. When connecting/disconnecting wires, pay enough atten­tion not to damage the connectors.

4. Be careful in removing or handling the part to which some
spacer or shield is attached for reinforcement or insulation.

5. When replacing chip parts (especially IC parts), first remove
the solder completely to prevent peeling of the pattern.

protective sheet attached to the transmitting glass. When
replacing the CCD IMAGE SENSOR, do not peel off this
sheet from the new part until immediately before it is
mounted in the OP BLOCK ASSEMBLY.

(3) The orientation of the OP LPF is an important factor for

installation. If there is some marking on the OP LPF, be
sure to note it down before removing and to reassemble it
very carefully as it was referring to the marking.

2.8 TAKE OUT CASSETTE TAPE

In the event that the set enters the emergency mode as it is
loaded with a cassette tape and the cassette tape cannot be
ejected with the EJECT button, manually, take it out of the set
according to the following procedure.

NOTE :

• If the mechanism comes into the unloading mode as the cas­sette tape is not held by hand, it results in tape damage.
(1) Disconnect the set from the power source.
(2) Remove the LOWER CASE ASSEMBLY and TOP OPE

UNIT (see Fig.C1, page 6).

(3) Connect a jumper wire to each pole of the LOADING

MOTOR as shown by the magnified view (Fig. 2-8-1).

BATTERY

(DC1.5V)

(4) While holding down the cassette housing by hand, con-

nect the jumper wires to a battery to run the mechanism
to the EJECT position four unloading. If this unloading
operation is performed as the cassette housing is not
held down by hand, the front lid of the cassette may dam­age the tape when it is ejected.

(5) For taking in the slack of the tape, run the mechanism to

the EJECT position as the front lid of the cassette is left
open, and turn the TAKE-UP GEAR in the forward direc­tion to wind up the tape. After confirming that the tape
has completely been wound up and the supply reel is
idling, take the cassette tape out of the cassette housing.
