ELECTRICAL ADJUSTMENT
3.1 PRECAUTION
The following adjustment procedures are not only necessary
after replacement of consumable mechanical parts or board
assemblies, but are also provided as references to be referred
to when servicing the electrical circuitry.
In case of trouble with the electrical circuitry, always begin a
service by identifying the defective points by using the measuring instruments as described in the following electrical adjustment procedures. After this, proceed to the repair, replacement and/or adjustment. If the required measuring instruments are not available in the field, do not change the
adjustment parts (variable resistor, etc.) carelessly.
3.1.1 Required test equipments
• Color (colour) television or monitor
• Oscilloscope: wide-band, dual-trace, triggered delayed
sweep
• Frequency counter
• Audio level meter
• Signal generator: RF / IF sweep / marker
• Signal generator: stairstep, color (colour) bar [NTSC]
• Recording tape
• Digit-key remote controller(provided)

3.1.4 Switch settings and standard precautions
The SW settings of the VCR and the standard precautions
for the electrical adjustments are as follows.
When using the Jig RCU, set its custom code to match
•
the custom code of the VCR.

3.1.5 EVR Adjustment
Some of the electrical adjustments require the adjustment
performed by the EVR system. The Main board assembly
have EEPROMs for storing the EVR adjustment data and user
setups.
Notes:
•
In the EVR adjustment mode, the value is varied with
the channel buttons (+, –). The adjusted data is stored
when the setting mode changes (from PB to STOP,
when the tape speed is changed, etc.). Take care to
identify the current mode of each adjustment item
when making an adjustment.
•
When changing the address setting in the EVR adjustment mode, use the Jig RCU or the remote controller
having numeric keypad with which a numeric code can
be directly input.
The remote control code of the Jig RCU corresponds
to each of the digit keys on the remote controller as
follows.
Digit-key 0 1 2 3 4 5 6 7 8 9
Code 20 21 22 23 24 25 26 27 28 29
•
As the counter indication and remaining tape indication are not displayed FDP during the EVR adjustment
mode, check them on the TV monitor screen.
•
When performing the EVR adjustment, confirm that the
FDP indication is changed to the EVR mode, as shown
below.
