CASSETTE CARE

Two common causes of trouble experienced when using cassettes are:—

(a)Tape jamming — Leading to uneven speed in playback, and

(b)Tape tangling — Where the tape wraps itself around vital parts of the mechanism.

To reduce the likelihood of these problems occurring, the following precautions should be observed.

Check that there are no loose layers of tape visible through the cassette centre window (see Fig. 1). Take up any loose layers, using a pencil or hexagonal barrelled ballpoint pen, before inserting the cassette into the machine (see Fig. 2).

If the cassette feels "tight" while performing operation shown in Fig. 2, the tape may be jamming due to "ridges" formed in the winding of the tape (visible through the centre window). These may be removed, in most cases, by fast winding of the cassette from one end to the other and back again.

Use only well-known brands of tape. Avoid use of C-120 cassettes.

Do not expose cassettes to direct sunlight, dust or oil, and do not touch the tape surfaces.

HEAD CLEANING

The tape heads, pinch roller and capstan require periodic cleaning. This removes particles of the metal oxide coating that wear off the tape and accumulate on these parts and impair performance. Switch off the power, press the Stop/Eject Button to open the cassette door, and press the Play Button. Clean the tape heads, pinch roller and capstan with a special tape head cleaner. Avaliable from most HiFi shops.

PREVENTION AGAINST ACCIDENTAL ERASURE

To prevent a recording on a cassette tape being erased accidentally, break off the tab on the rear of the tape, as in the diagram. Now recording on this side

is no longer possible. You can render this protection ineffective by covering the hole with a piece of adhesive tape.

AC CONNECTION

Plug the power cord into an AC outlet having 120V ,60Hz only. Connecting this unit to other power sources may damage the unit.

NOTES:

*The AC polarized to help minimize the possibility of electric shock. If the polarized plug does not fit into a nonpolarized AC outlet,

do not file or cut the wide blade; it is the user`s responsibility to have an electrician replace the obsolete outlet.

*The power cord should be unplugged from the outlet

when the unit is not going to be used for a long period of time.
