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.
5.1.16. 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 personalinjury 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.
5.1.17. 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.
5.1.18. MODEL NO. IDENTIFICATION MARK
Use Marks shown in the chart below to distinguish the different models included in this Service
Manual.
