Be especially careful in the following conditions:

÷

When the unit is brought from a cold place to a warm place, and there
is a large temperature difference.

÷

When a heater starts operating.

÷

When the unit is brought from an air-conditioned place to a place of
high temperature with high humidity.

÷

When there is a large difference between the internal temperature of
the unit and the ambient temperature, or in conditions where conden-
sation occurs easily.

Cleaning the head section

There are precisely aligned parts around the heads, including the tape guides.
When cleaning, pay special attention so as not to apply shock to them.

Beware of condensation

When water vapor comes into contact with the surface of a cold
material, condensation is produced.
If condensation occurs, correct operation may not be possible, or
the unit may not function correctly.
This is not a malfunction, however, and the unit should be dried-out.
(To do this, turn the ON/STANDBY switch ON and leave the unit as it
is for several hours.)

Maintenance

Demagnetizing the head

When the recording / playback head is magnetized,
the sound quality will deteriorate. In such a case,
demagnetize the head using a commercially avail-
able demagnetizer (head eraser).

Cleaning the heads and peripheral compo-
nents

For maintaining the best condition of the deck and
for longer service life, always keep the heads (re-
cording / playback / erase), capstan and pinch roller
clean. To clean them, perform the following:
1. Open the cassette holder.
2. Using a cotton swab dipped in alcohol, clean the

head (recording / playback / erase), capstan and
pinch roller carefully.
