"Protected" cassettes may be re-recorded by simply xing a piece of adhesive tape over the hole where the tab has been
removed. This takes the place of the tab and your machine can then be engaged in the record-mode.
A protected cassette will prevent the Record key from being pressed. If at any time you attempt to record and this key will
not engage, do not force the mechanism or damage will result. Check that a cassette has been loaded and that the
erase-lock tab has not been removed.
MAINTENANCE
Your recorder requires no routine maintenance and under no circumstances should you attempt to lubricate any parts of
the machine. However, parts of the machine, coming into direct contact with the tape, do require periodic cleaning to
ensure continuing good performance.
The tape heads (erase and record/play) may be cleaned using a cotton ball moistened with a drop of isopropyl alcohol or
proprietary tape head cleaner. The pinch-roller and capstan shaft may be cleaned in a similar manner. To gain proper
access to these parts, remove any cassette from the compartment and leave the lid raised. Pressing the PLAY key will
engage the mechanics and move all parts into view. It will be easier to clean the entire surface of the pinch-roller if the
power source is connected (batteries or mains), so that the roller and capstan shaft rotate. It is suggested that a
proprietary Cassette Head Cleaning Cassette be used after manually cleaning the Record/Play head in order to restore
the polish and remove surface lm.
Erase Head
PLAY
Failure to maintain the tape heads in clean condition will result in mu ed reproduction, poor recordings and incomplete
erasure. Failure to maintain the pinch-roller and capstan shaft in clean condition, is likely to cause the tape to entangle
and spill out of the cassette. Do not touch the tape head with any metallic or sharp-pointed object.
