RCA 390 - Manual (Page 11)

Video Cassettes
RCA recommends that RCA cassettes be used with this
unit. The tape in RCA cassettes is of high-quality formula­
tion, intended for use with multi-speed VHS video cas­
sette 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 dam­
aged or mishandled can contaminate the VCR heads.
This can cause a snowy picture or a missing picture dur­
ing 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 clean­
ing tape (RCA Stock No. AV009). It is available from your
dealer and many electronic supply stores.
Erase Protection
To prevent erasing a recording you want to keep, remove
the safety tab from the back of the cassette as shown in
the illustration. Recording is impossible when this tab is
removed. To record again on a cassette that has the tab
removed, simply cover the hole with vinyl tape.

Recording Speed
This information will help you decide which tape speed to
use when recording.
• SP: Standard Play uses the most tape. Video 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 uses one-half as much tape as SP. This
speed is provided primarily for playing tapes recorded
on older machines that do not have SLP.
• SLP: Super Long Play uses one-third as much tape as
SP, SLP has slightly more "picture noise" than LP in
normal playback (which may not be noticeable). Your
VCR's special effects (search, stop action, slow
motion, and frame advance) ere designed for optimum
performance at the SLP speed.
To prevent erasure,
break off the tab To record again, cover
the hole with vinyl
tape
Cassette Care and Storage
Follow these directions for continued high-quality per­
formance 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
normal room temperatures. Avoid extreme heat and
humidity. Extreme 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/ptayback heads.
