This  spec.  sheet  applies  to  PU02A  Chassis  applied  PDP  TV
all models manufactured in TV factory.

(1) Because this is not a hot chassis, it is not necessary to use

an  isolation  transformer.  However,  the  use  of  isolation
transformer will help protect test instrument.

(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of

25 

c

C  ± 5  cC  of  temperature  and  65  %  ± 10  %  of  relative

humidity if there is no specific designation.

(4) The input voltage of the receiver must keep 100 V - 240 V,

50 / 60 Hz.

(5) The receiver must be operated for about 5 minutes prior to

the adjustment when module is in the circumstance of over
15 cC

- In case of keeping module is in the circumstance of 0 cC,

it should be placed in the circumstance of above 15 cC for
