Please heed the points listed below during servicing and inspection.

Heed the cautions!Spots requiring particular attention when servicing, such

as the cabinet, parts, chassis, etc., have cautions indicated

on labels or seals. Be sure to heed these cautions and the

cautions indicated in the handling instructions.

Caution concerning electric shock!(1) An AC voltage is impressed on this set, so touching in-

ternal metal parts when the set is energized could

cause electric shock. Take care to avoid electric shock,

by for example using an isolating transformer and

gloves when servicing while the set is energized, un-

plugging the power cord when replacing parts, etc.

(2)There are high voltage parts inside. Handle with extra

care when the set is energized.

C ti i di bl d

Inspect for safety after servicing!Check that all screws, parts and wires removed or discon-

nected for servicing have been put back in their original po-

sitions, inspect that no parts around the area that has been

serviced have been negatively affected, conduct an insu-

lation check on the external metal connectors and between

the blades of the power plug, and otherwise check that

safety is ensured.

(Insulation check procedure)

Unplug the power cord from the power outlet, disconnect

the antenna, plugs, etc., and turn the power switch on. Us-

ing a 500V insulation resistance tester, check that the in-

sulation resistance between the terminals of the power

plug and the externally exposed metal parts (antenna ter-

minal, headphones terminal, microphone terminal, input

terminal, etc.) is 1Mor greater. If it is less, the set must

be inspected and repaired

SAFETY PRECAUTIONSThe following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECKBefore returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis

resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the

power cord is less than 460 kohms, the unit is defective.

LASER RADIATIONDo not stare into beam or view directly with optical instruments, class 3A laser product.
