This service manual contains technical information which will allow service personnel to understand and
service this model.
If the circuit is changed or modified, this information will be followed by supplementary service manual to be
filed with original service manual.
Note:
1. Adjustment procedures, Disassembly Procedures and Assembly Procedures for Mechanism Chassis are separate
volume from this service manual. / Please refer to the service manual for Z-Mechanism Chassis. (Order No.
VRD9802005C2)
2. The Model No. is indicated on the Schematic Diagram and Circuit Board Diagrams as follows.

2. GENERAL DESCRIPTIONS
2.1. SERVICE INFORMATION
2.1.1. MICROPROCESSOR RESET
When the Microprocessor IC6001, MAIN C.B.A. and/or Back-up Battery B6001 are replaced, read following
procedure carefully and proceed it.
Reasons:
There is a RAM in the IC6001, which is backing up:
1. TV Tuning Data.
2. PG shifter Adjustment Data
3. Option Setting Data
When IC6001, MAIN C.B.A. and/or Back-up Battery B6001 are replaced, all above listed data become not
available.
These data are backing up by using the power source of:
AC connected: AC Power source
AC Disconnected: Back-up Battery B6001
Method:
Before replacing IC6001, MAIN C.B.A. and/or B6001:
1. Take a note that stored TV broadcasts channels.(Because , its user may store TV broadcasts by manually other than
"Auto Tuning" operation and it is also erased.)
After replacing IC6001, MAIN C.B.A. and/or B6001:
1. Turn on the VCR.
2. Connect a jumper wire between TL7509 and TL7510 for 1 second to reset IC6001.
After resetting IC6001:

http://cxema.ru
1. Store TV broadcasts channels by Auto/Manual Tuning using the On Screen Display according to note which taken before
replacing IC6001, MAIN C.B.A. and/or B6001.
2. Set the Direct Rec function to OFF using On Screen Display if necessary. / (Because, Direct Rec function is set
automatically to ON after resetting IC6001.) / [Direct Rec Function] / OFF: Normally set at this position. / ON: This
settingenables Direct Rec. / AV1 Input(A1) becomes exclusive channel for Direct Rec.
3. Perform the PG SHIFTER ADJUSTMENT. / (Refer to the Electrical Adjustment Procedures.)
Note:
1. It should be performed before tuning.
2. Do not cut off the power source during reset.
