NOTE:

VIDEO HEAD CLEANING

VIDEO HEAD CLOGGING

The video heads are the means by which the TV/VCR reads the picture from the tape during playback. In the unlikely event that the heads become dirty enough to be clogged, no picture will be played back. This can easily be deter- mined if, during playback of a known good tape, there is good sound, but no picture (picture is extremely snowy). If this is the case, use a high quality head cleaning system or have them cleaned professionally.

VIDEO HEAD CLEANING

Video head cleaning is needed when the playback picture becomes unclear. This signifies that the heads are getting dirty and can occur when playing poor quality or damaged tapes. If the heads require cleaning, use a equivalent high quality chemical non-abrasive (wet) head cleaning tape or have them cleaned professionally. If playing a head cleaning tape in the VCR once does not improve the picture, play it several times before requesting service.

DO NOT ATTEMPT TO CLEAN THE VIDEO HEADS OR SERVICE THE UNIT BY REMOVING THE REAR COVER.

Video heads may eventually wear out and should be replaced when they fail to produce clear pictures.

To help prevent video head clogging, use only good quality VHS tapes. Discard worn out tapes.

NOTES

Auto Clock Setting

Notes for Canadian customers regarding the clock feature of the TV-20F243:

The XDS signals are carried only by certain broadcast television stations (for example, the signal is carried by most Public Broadcasting Service stations). You must be able to receive a station carrying the XDS signal to use the Auto Clock Setting to set your TV/VCR’s internal clock. If you live in an area that does not broadcast XDS signals, you must set the clock manually. Please see page 16 for instructions on how to manually set your TV/VCR’s clock.

Special note for residents of Newfoundland:

The Auto Clock Setting cannot be used to set the TV/VCR’s internal clock to Newfoundland time. The time zone command does not include a setting for the Newfoundland time zone. Trying to use the Auto Clock Setting in the Newfoundland time zone could result in an incorrect time setting or no setting at all. Please set your TV/VCR’s clock using the Manual Clock Setting.
