Ejecting the cassette tape and then reinserting it will reset the tracking to the
Neutral position.
5.1.19. BLACK SCREWS ON THE CHASSIS
Black Screws are used on the Mechanism Chassis to identify screws that require
adjustment.
5.1.20. HOW TO RESET ALL COMBINATION VCR MEMORY FUNCTIONS
To reset (clear) the select language, channel auto set and set clock functions to
their initial power on condition (power on, no cassette inserted), hold down the
PLAY/REPEAT and FF buttons of VCR operation panel on the unit together for more
than 5 seconds.
Power will shut off.
5.1.21. HOW TO CONFIRM AUTO CLOCK SET FEATURE
1. Connect an RF cable from the output of one unit to the input of the test unit.
2. Select corresponding RF channels.
3. Playback a recording of P.B.S. channel including clock set data and confirm this
feature.
5.1.22. VARIABLE VOLTAGE ISOLATION TRANSFORMER
An Isolation Transformer should always be used during the servicing of
Combination VCR whose chassis is not isolated from the AC power line. Use a
transformer of adequate power rating as this protects the technician from accidents
resulting in personal injury from electrical shocks. It will also protect Combination
VCR from being damaged by accidental shorting that may occur during servicing.
Also, when troubleshooting the above type of Power Supply Circuit, a variable
isolation transformer is required in order to increase the input voltage slowly.
5.1.23. SPECIAL NOTE
All integrated circuits and many other semiconductor devices are electrostatically
sensitive and therefore require the special handling techniques described under the
"ELECTROSTATICALLY SENSITIVE (ES) DEVICES" section of this service manual.
