2.1.2. CAUTION FOR AUTO TUNING
PROCEDURE
AutoTuning will start bythe following procedure.
1. Connect the DIN-RFCable.
2. Connect the AC Mains Lead.
3. Turn on the VCR. / Auto Tuning will start. / Auto Tuning searches
for TV stations from VHFminimum to UHFmaximum and
memorizes everytuned program position. Other program
positions are skipped.
Auto Tuning takes five or more minutes to complete its search.
Donot touch the VCR during Auto Tuning.
Auto Tuning will stop halfway, ifthe VCR isoperated or the aerial
lead and/or the mains lead are disconnected.
Incase the VCR stopped during Auto Tuning, the VCR have to be
reset and restarted. See the following item 2.

NOTE
1. Ifthe VCR isturned on with the antenna not connected, all
channelsare skipped. Therefore, firmlyconnect the antenna and
then turn the VCR off and on againto execute Auto tuning.
2. When Auto Tuning iscanceled halfway, Auto Tuning isnot
executed even ifthe VCR isturned off and then turned on again. /
Inthiscase, Auto Tuning have to be restarted bythe following
procedure.
A. Press EJECTand remove the Video cassette.
B. Keep UPand DOWNon the VCR pressed simultaneouslyfor 3
seconds or more during the VCR on. / The channel displayed
on the VCR displaydisappears for amoment then changes to 2.
C. Turn off the VCR and then turn iton. Auto Tuning commences.
