2.1 CLEANING
The parts of the cassette deck that are in contact
with the tape surface should be cleaned regularly,
otherwise the sound quality will be greatly reduced.
Cleaning of capstans and pinch rollers is particularly
important to avoid wow and flutter.
If the cassette deck is used every day, cleaning
should be performed at least once a month.
The cleaning can be done with cotton wool or a
piece of flannel wrapped around a small stick and
moistened with pure alcohol or methylated spirit.
A kit intended for this purpose, Tandberg Profes-
sional Tape Head Cleaner”’, is available.
NOTE!
Do not use solvents, such as acetone or trichlor-
ethylene, as these may damage the heads.
How to clean
1. Press the EJECT button, and remove the
plastic lid from the cassette compartment.
2. Push the cassette compartment down to
closed position.
3. Clean the record/playback head (A), erase
head (B), tape guide (C), capstans (D) and
pinch rollers (E). Do not use too much
cleaning liquid on the pinch rollers, and dry
them afterwards.
DO NOT USE ANY SHARP OBJECTS WHEN
CLEANING. DO NOT TOUCH THE ADJUST-
MENT SCREWS.
4. Check the surrounding area for dust and de-
posits from the tape. Clean if required.
Cleaning should be performed both before and after
adjustments.
2.2 DEGAUSSING
A marked increase in background noise from the
tape may indicate that the heads or other parts
in the tape path should have the residual magnetism
removed (degaussing).
If required, degaussing should be carried out as
follows. Switch off the deck. Remove the
cassette from the deck. Remove the plastic

gausser slowly past each one of the metal parts
normally in contact with the tape. Take great care
not to let the degausser touch the heads or metal

gausser until it is at least 3 ft from the deck.
Degaussing should be performed both before and
after adjustments.
2.3 LUBRICATION
The capstan motor and the reel motors may
require lubrication from time to time. The
interval between each lubrication should be
at least 3000 hours of operation.
Use the following types of oil:
Capstan motor: ANDEROL 465 from Tenneco
Chemicals, U.S.A., or oil supplied by Tandberg.
Reel motors: NUTO H36 (also called SPINESSO
34) from Esso.
NOTE!
Use only one drop of oil for each motor.
