IMPOTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service peronnel only.
SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE 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 dis-
charging the high voltage completely.
X-RAY This receiver is designed so that any X-Ray radiation is kept to an ab- solute minimum. Since certain malfunctions or servicing many pro- duce potentially hazardous radiation with prolonged exposure at close range, the following precautions should be observed: 1. When repairing the circuit, be sure not to increase the high voltage to more than
33.0 kV (at beam 0
µ
A) for the set.
2. To keep the set in a normal operation, be sure to make it function on 29.5
±
1.5kV
(at beam 1.7 mA) 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 repairs, never forget to check for such high voltage after the work.
3. Do not substitute a picture tube with unauthorized 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 the 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, iso- lation resistor- capacity networks, mechanical insulators etc.

ADJUSTMENT PRECAUTION
The model is a mixture of the adjustment items of I
2
C BUS-CONTROL and the existing analog adjustment. Moreo-
ver, since the adjustment with I
2
C BUS-CONTROL is composed of the items which are set with the initial values
(preset values) alone and the data variable items, refer to the following.
1) Setting method to the microcomputer service mode
1When the TP1001/1002 are short-circuited, enter into the service mode (I
2
C BUS CONTROL adjustment
mode).
2The modes can be sequentially selected with the CH DOWN key of R/C.(or button of set behind door.) 3The modes can be sequentially selected in the reversed order of 2with the CH UP key of R/C. (or button of
set behind door.)
4The data can be converted with the VOLUME UP/DOWN key of R/C. (or button of set behind door.) 5When the short circuit between the TP1001/1002 is cut off, it will be released from the service mode.
2) Initial value (preset value) setting
1When the MAIN POWER switch set at the service mode side is turned on, the initial value will be automatically
set only on the new E
2
PROM (discriminated with the head 4 bytes).
2The initial data is set as shown in the attached sheets. 3Take care that there are the items which need be changed and the items in which the initial values continue
set. Instruct that it must set at the service mode side as shown in Item 2-1and the MAIN POWER switch must be turned on when the lamp is first turned on after the chassis is assembled. Take care that the beam current may excessively flow if the lamp is turned on unless E
2
PROM is initialized.
3) Since the E
2
PROM memory is submitted with the attached sheets for reference, use it.
