Video Cassettes
RCA recommends that RCA cassettes be used with this
unit. The tape in RCA cassettes is of high-quality
fonmuiation, intended for use with multi-speed VHS
video cassette recorders. It has been manufactured to
RCA’s critical specifications for excellent performance
with RCA VCR's. Use of tape not meeting these
specifications could considerably reduce the
performance of your VCR.
Use of poor quality tapes or tapes that have been
damaged or mishandled can contaminate the VCR
heads. This can cause a snow
7
picture or a missing
picture during playback. Because RCA has no control
over the type of tape purchased or rented by consumers,
head cleaning is not covered by RCA's warranty. It is
considered normal maintenance.
Playing a new RCA tape for approximately 30 minutes
often will clean the VCR heads and improve your
picture. If a snowy' picture or missing picture condition
persists, consider the use of a chemical non-abrasive
head cleaning tape (RCA Stock No. AV(K)9W). It is
available from your dealer and many electronic supply
stores. Be sure to follow the directions with the head
cleaning kit carefully. Improper use of a head cleaner
may damage your VCR.
Erase Protection
To prevent erasing a recording you want to keep, remove
the record-protect tab from the back of the cassette as
shown below. Recording is impossible when this tab is
removed. To record again on a cassette that has the tab
removed, simply cover the hole with \inyl tape.
Cassette Playing Times and Speeds
The playing times and counter readings below are
approximate. Also, it is assumed the counter is set to
0000 at the start of the tape.

Recording Speed
This information will help you decide w-hich tape speed
to use when recording.
• SP: Standard Play provides the best picture but the
shortest recording time (2 hours with a T-120 tape),
y^ideo recorded at this speed has the least “picture
noise” (snow) in normal playback. Pre-recorded tapes
use SP for this reason and also because all VHS
recorders have this speed.
• LP: Long Play provides twice the recording time as
SP (4 hours with a T-120 tape). This speed is provided
primarily for playing tapes recorded on older
machines that do not have SLP.
• SLP: Super Long Play provides three times the
recording lime as SP (6 hours with a T-120 tape). SLP
has slightly more “picture noise” than SP in normal
playback (which may not be noticeable). Your VCR's
special effects (search and stop action) are designed for
optimum performance at the SLP speed.
Cassette Care and Storage
Follow these directions for continued high-quality
performance from your cassettes,
• When you are finished with a cassette, rewind it and
remove it from the VCR.
• Never attempt to force open the cassette door.
• Store cassettes vertically in their protective boxes at
norma! room temperatures. Avoid extreme heat and
humidity. E.xtreme heat can warp the cassette or cause
the tape to stretch excessively.
• Be especially careful to keep dust from entering the
cassette and the VCR mechanism. All dust is abrasive
and it will cause excessive wear of both the tape and
the VCR's recording/playback heads.
