In case that defective EEPROM of PAL models is replaced, to operate these sets from the initial state MP KEY
must be repaired as well before delivering to the customer.
If MP KEY isn’t repaired the setting of RF OUT channel or LANGUAGE might be different from that for cus-
tormer’s country.
•MP KEY : In case of PAL VCR if holding the REC button on the front panel and the CLEAR button on the
remote control handset for 5 ~ 7 seconds with power being switch all and no tapes,
OK is displayed at FLD for FLD models and LED becomes on for LED CLOCK models.
This is the state that initializing EEPROM is finished.
(In case of PAL VCP if holding the REC button on the front panel and the MENU button on the
remote control handset for 5 ~ 7 seconds with power being off and no tapes, All the LED DOTs
become on. This is the state that initializing EEPROM is finished.)
•MP KEY's function : MP KEY sets EEPROM's data up to the initial state.

1. DETECT NEW EEPROM (OPTION EDIT SCREEN)
- Eeprom EDIT screen automatically appears if replacing Eeprom.
• Setup option data using the cursor Up/Down key of a remote
control.
(Setup upon BOM depending on OPT1~OPT6 model)
• Since an initial remote control is set to LG for LG model, appro-
priately set optional data using the cursor Up/Down key.
2. EEPROM WRITED COMPLETE SCREEN
- Writes data on EEPROM by using REMOCON "OK".
- If completing the option data screen with a menu key, Powering
Off is automatically done and the option edit screen is arranged.
3. PG ADJUST
a) Insert the PAL SP Test Tape and play.
Note - Adjust the distance of X, pressing the Tracking(+) or
Tracking(-) when the “ATR” is blink after the PAL SP Test
Tape is inserted.
b) Press the Auto PG KEY on JIG Remocon(1’st) or Press “REC”
key on set and “CLEAR” key on Remocon.(Then check the blink
“TRK OK” on CLK/LED-TRK is a Initial)
c) Press the Auto PG Key on JIG Remocon again (2’nd) or press
“REC” key on set and “CLEAR” key on Remocon again.(Then
check the blink “PG NG > PG OK” on CLK/LED.)
4. EEPROM INITIAL
- SETUP is displayed in the field if pressing the FRONT REC KEY
with the remocon number "CLEAR" key pressed in the status of
powering Off.
- AUTO SEARCH is done since the initial screen of ACMS is ser-
viced if powering On.
- Check basic operation (PLAY/RECORD...)

• Adjustment Procedure
a) Insert the PAL SP Test Tape and play.
Note - Adjust the distance of X, pressing theTracking(+) or Tracking(-) when the “ATR” is blink after the
PAL SP Test Tape is inserted.
b) Press the Auto PG KEY on JIG Remocon(1’st) or Press “REC” key on set and “CLEAR” key on
Remocon.(Then check the blink “TRK OK” on CLK/LED-TRK is a Initial)
c) Press the Auto PG Key on JIG Remocon again (2’nd) or press “REC” key on set and “CLEAR” key on
Remocon again.(Then check the blink “PG NG > PG OK” on CLK/LED.)
• Check the PG
a) Connect the CH1 of the oscilloscope to the H/SW and CH2 to the Video out for the VCR.
b) Trigger the mixed Video Signal of CH2 to the CH1 H/SW(W501, W502), and then check the distance
(time difference), which is from the selected A(B) Head point of the H/SW(W501, W502) signal to the
starting point of the vertical synchronized signal, to 6.5H ±0.5H (416µs, 1H=64.0µs).
