2. Remove t h e 4 screws located at t h e rear of t h e case and
the 1 located at b o t t o m w i t h a © screwdriver. Carefully
slide t h e body f o r w a r d f r o m the case.
3. To install the body in the case, place the case horizon-
tally a n d slide the body into t h e case using the rails
located at t h e b o t t o m of the case. Then, place the body
vertically a n d engage the case front edge into the front
panel groove.
4. Temporarily insert the case retaining s c r e w s a n d t h e n
t i g h t e n t h e m evenly.
5. Install the C H 3 a n d C H 4 POSITION knobs.

A voltage of 1 6 k V is applied t o the CRT socket a n d
anode c a p . Before r e m o v i n g t h e case, turn the p o w e r
off a n d pull o u t the p o w e r plug. After r e m o v i n g t h e case,

REMOVING/INSTALLING CRT
1. W h e n servicing CRT, d o n o t loosen t h e CRT band. Only
remove the CRT retaining screws, then slide the CRT
b a c k w a r d a n d raise t h e socket. The CRT can be remov-
ed easily.
2. Insert the CRT f r o m t h e socket side until the CRT c o m e s

A high tension voltage is remained at the anode of the
CRT. Before r e m o v i n g the CRT, connect the anode to
the g r o u n d via a 1 0 0
kil
load for 5 seconds to discharge
the voltage.
TROUBLESHOOTING
1. Confirm that t h e voltage selector is set to t h e correct
position.
2. If one of the m o d e LEDs does n o t light, the unit will n o t
operate correctly. W h e n using the unit, c o n f i r m t h a t t h e
LED lights up.
3. To service the unit effectively, isolate the failure first.
Then, remove the case a n d check t h e w i r i n g , P.C.B,
pattern and parts.
4. A l o w voltage p o w e r supply will affect the circuitry.
Do not use the l o w voltage p o w e r supply for checking.
