PIONEER PDP-4270XD PDP-427XD PDP-4270XA PDP-427XA
ADJUSTMENT- At shipment the unit is adjusted to its best conditions. Normally, it is not necessary to readjust, even if an assembly is replaced. If the adjustment is shifted of if it becomes necessary to readjust because of part replacement , perform the adjustment as described below.
- Any value changed in service mode will be stored in the memory as soon as it is changed. Before readjustment, take not of its original values for reference in case you need to restore the original settings.
- Use a stable AC power supply.
ADJUSTMENT REQUIRED WHEN THE SET IS REPAIRED OR REPLACED.

Among above, which are not followed by (>) symbol need no service adjustments after replacement.
When replacing the Main Assy', be sure to do the final SETUP
ADJUSTMENTS REQUIRED WHEN PART IS REPLACED
For the parts described in the list below, replacement is required
for the whole assembly, not only the defective part. If any part listed
below is identified as defective and needs replacement, replace the
whole assembly and make necessary adjustments after replacement.
The whole assembly must be replaced, because adjustments and data
rewriting for the assembly at the level of production line are required.

HOW TO COPY BACKUP DATA
When the digital assembly is replaced with one for service [Usual Service]
- Copying using Factory Menu
- After the digital assembly is replaced with one for service, be sure to check if 'NO DATA!' is set for "DIG.EEP" on the PANEL INFORMATION.
- If copying of back up data fails in the above procedure, the Red LED lights, and the Blue LED flashes, as warning that no backup data was copied.
- If both 'digital' and 'Sensor Assemblies' are to be replaced, first replace the 'Sensor' assembly, turn the unit ON, and back OFF again, then replace the 'digital assembly'
- Copying using RS-232 commands
- Switch the RS-232C/SR+ setting to RS-232C so that RS-232C commands can be received.
- Turn ON the unit, using the remote control unit by issuing the 'PON' command. Then issue'FAY' command
- Issue the 'BCP' command to transfer the data stored in the EEPROM for back up.
- Turn Power Off
- Plug in the AC cord, press the Power switch ON the unit to set it ON, then enter Standby Mode.
- Turn ON the Power, using remote control unit, then panel Factory mode. [Panel Information > [key Dn] > ETC [key +] > [key 'Set'] > Backup Data:NoOPRT [key >>] > Backup Data :Transfer [key 'Set' (5sec)].
- Turn the Power OFF.
