2. GENERAL DESCRIPTIONS
2.1. SERVICE INFORMATION

http://cxema.ru
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:
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.
