Preparation
xNotes on cassettes
• Any standard cassette can be used, but the optional Sony leaderless cassette DC-60 or DC-90 is
recommended. The use of a TYPE
II
(High position) or TYPE
IV
(metal) cassette is not advisable.
• Choose a cassette of suitable length. The recording time on each side of these cassettes is as follows:
Sony DC-60 approx. 30 minutes (4.8 cm/s)
Sony DC-90 approx. 45 minutes (4.8 cm/s)
• The use of cassettes whose running time is longer than 90 minutes (total time) are not advisable.
• The letter A on the Sony cassette is embossed to help you distinguish that side of the cassette in a
dimly lit area.
To prevent accidental erasure
When the unit is operated in the recording mode, any previous recordings will be automatically
erased. For this reason, cassettes incorporate a safety device to prevent any accidental erasure.
When the small tabs at the rear of a cassette are broken off, an interlock on the unit will be activated,
preventing recording.*
To protect the recording on side A, break off the tab of that side.
To protect the recording on side B, break off the tab of that side.
To reuse a cassette for recording after the tabs have been removed, simply cover each slot with a small
piece of plastic tape. Do not stick any material on any other part of the cassette except the circled part,
as illustrated below.
* When the cassette is loaded for telephone recording with the tabs broken off and the TEL REC
button is pressed, the beep tone is heard and the TEL REC button does not operate.
When the cassette is loaded for dictating with the tabs broken off and the function selector is set to
DICT, recording cannot be made and the beep tone is heard.
