1. Application Object

These instructions are applied to all of the PDP monitor, RF-

02RA.

2. Notes

(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±5°C of temperature and 65±10% of relative humidity if

there is no specific designation.

(4) The input voltage of the receiver must keep 110~240V,

50/60Hz in adjusting.

(5) The receiver must be operated for about 15 minutes prior

to the adjustment.

1) After receiving 100% white pattern, the receiver must be

operate prior to adjustment.(Or white condition in HEAT-

RUN mode)

2) Enter into HEAT-RUN mode

- Select the HEAT-RUN OFF by pressing ADJ Key on

Remote Control for adjustment.

- Press the VOL + Key in HEAT-RUN OFF.

(OSD display HEAT-RUN WHITE and screen display

[ Single color pattern of HEAT-RUN mode uses to check

PANEL.(RED/BLUE/GREEN)

[Caution] If you turn on a still screen more than 20 minutes, a

afterimage may be occur in the black level part of the

screen.

Each PCB Assy must be checked by the Check JIG Set before

whole assembly. (Be careful the POWER PCB Assy not to

damage to PDP Module)

3-2. Connection Diagram for Measuring

Refer to Fig 1.

3-3. Adjustment Method(POWERWELL)

(1) Va Adjusment

1) Connect pin 1 of CN205 to (+) jack of D.M.M.

2) After turning the VR3(Va ADJ), voltage of D.M.M

adjustment as same as Va voltage which on label of

panel right/top.(Deviation : ±0.5V)

(2) Vs Adjustment

1) Connect pin 1 of CN207 to (+) jack of D.M.M.

2) After turning the VR6(Vs ADJ), voltage of D.M.M adjust

as same as Vs voltage which indicated on label of panel

right/top.(Deviation : ±0.5V)

(3) -Vy Adjustment

1) Connect pin 1 of CN208 to (+) jack of D.M.M.

2) After turning the VR5(-Vy ADJ), voltage of D.M.M adjust

as same as -Vy voltage which indicated on label of

panel right/top.(Deviation : ±0.5V)

(4) Vsetup Adjustment

1) Connect pin 5 of CN208 to (+) jack of D.M.M.

2) After turning the VR4(Vsetup ADJ), voltage of D.M.M

adjust as same as Vsetup voltage which indicated on

label of panel right/top.(Deviation : ±0.5V)
