• HOW TO CHANGEDTHE CERAMIC FILTERS
This model is used two ceramic filters of CF1 and CF2.
You must used same type of color marked ceramic filters in
order to meet same specifications.
Therefore, the ceramic filter must changed two pieces together
since it’s supply two pieces in one package as a spare parts.

PRECAUTION
1. Clean the following parts with a denatured-alcohol-moistened
swab :record/playback head playback head
pinch roller erase head
rubber belt capstan
2. Demagnetize the record/playback head with a head demagne-
tizer. (Do not bring the head demagnetizer close to the erase
head.)
3. Do not use a magnetized screwdriver for adjustments.
4. After the adjustments, apply suitable locking compound to the
parts adjusted.
5. The adjustments should be performed with the rated power sup-
ply voltage unless otherwise noted.

(Normal speed)
1. Deck A to playback mode.
2. Adjust the RV303 for 2,985 – 3,015Hz reading on digital fre-
quency counter.
3. Frequency difference between the beginning and the end of the
tape should be within 1% (30Hz).
(High speed)
4. Deck B to record mode.
5. Deck A to high speed playback mode.
6. Confirm that the reading of the digital voltmeter becomes 5,500
– 6,500Hz.
7. Frequency difference between the beginning and the end of the
tape should be within 1% (30Hz).
