RCA 390 owner manual Video Cassettes, Is not covered by RCAswarranty. It is considered normal

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'swarranty. 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. AVO09). It is available from your dealer and many electronic supply stores.

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) are dealgned for optimum performance at the SLP speed.

Cassette Care and Storage

Follow these directions for continued high-qualityper- 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/playback heads.
