IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only. SERVICE OF HIGH VOLTAGE SYSTEM AND PIC- TURE TUBE When servicing the high voltage system, remove static charge from it by connecting a 10K ohm Resistor in series with an insulated wire(such as a test probe) between picture tube dag and 2nd anode lead. (AC line cord should be disconnected from AC outlet.)
1. Picture tube in this receiver employs integral implosion protection. 2. Replace with tube of the same type number for continued safety. 3. Do not lift picture tube by the neck. 4. Handle the picture tube only when wearing shatterproof goggles and after discharging
the high voltage completely.
X-RAY This receiver is designed so that any X-Ray radiation is kept to an absolute Minimum. Since certain malfunctions or servicing may produce potentially hazardous radiation with prolonged exposure at close range, the followin precautions should be observed:
1. When repairing the circuit, be sure not to increase the high voltage to more than 23.5kV(at
beam 0.1
µ
A) for the set.
2. To keep the set in a normal opeartion , be sure to make it function on 22.0kV
±
1.5kV(at
beam 800
µ
A) in the case of the set. The set has been factory - Adjusted to the above-
mentioned high voltage.
*If there is a possibility that the high voltage fluctuates as a result of the repairs, never
forget to check for such high voltage after the work.
3. Do not substitute a picture tube with unauthorizerd types and/or brands which may
cause excess X-ray radiation.
BEFORE RETURNING THE RECEIVER Before returning the receiver to the user, perform the following safety Checks. 1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not
lodged between the chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers,
cabinet backs, adjustment and compartment covers or shields, isolation resistor- ca- pacity networks, mechanical insulators etc.

ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two different ways: through the I
2
C bus control and in the conventional
analog manner. The adjustments via the I
2
C bus control include preset-only items and variable data.
1. Setting the service mode by the microprocessor.
1. Short JA 122 & JA 124 for 1 second and release to switch to the service mode position, and the
microprocessor is in input mode. (Adjustment through the I
2
C bus control). (Use JWS Key to set as
well).
2. Press the CH DOWN / UP key on the remote controller to get ready to select the mode one by one. 3. Press the CH DOWN / UP key on the remote controller to select the modes reversibly one by one. 4. Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified. 5. Short JA 122 & JA 124 for 1 second and release to switch to the normal mode (OFF) position, and the
microprocessor is in out of the service mode.
2. Factory Presetting.
1. Short JA 122 & JA 124 for 1 second and release to switch to the service mode position and turn on the
main power switch.Initial values are automatically preset, only when a new EEPROM is used (Judge with the first 4 bytes ).
2. The initial data are preset as listed in page 5 & 6. 3. Make sure the data need modify or not (Initial data).
Note: Once the chassis has been assembly together and ready to be POWER ON for the FIRST TIME,
make sure to short JA122 & JA124 to switch to the service mode position first and then turn on the main power switch (See 2-(1) above). Precaution: If haven't done this initiation, it may possibly generate excessive Beam current.
3. For reference please check with memory map
