To Edit and Splice Tape
NOTE: It isimpossible to editand spliceone trackof
tape without affecting the second track, therefore re-
cordings to be edited should be iimited to one track
only.
1. Tape recordings may be edited by cutting out
unwanted sections, or by joining selections into another
sequence. Announcements can be inserted between
selections etc. Unused sections of tape can be spliced
together for reuse.
2. For best results cut tape on a slight diagonal,
join ends together with splicing tape on the glossy side
and trim off any excessive width.
Erasing Recorded Material
When the "Record" button is depressed, the
erase head is positioped automatically erasing any pre-
vious recording before a new one is made. Material
no longer needed may be erased without recording by
depressing the "Record" button and turning the 'Yol-
ume" control to the minimum, (or extreme counter-
clockwise position). Only one track is erased at a
time. To erase the second track reverse the reels
and repeat the above operation.
To Use Recorder As a Public Address System
Insert the microphone plug into the "Microphone"
jack. Plug in an extension speaker and depress the
"Record" button. Set the "Tone" and "Volume" con-
trols to the desired level. A recording can be made
at the same time by placing a tape on the unit in the
normal manner.
NOTE: When using the public address feature keep
themicrophone as laraway from thespeakers aspos-
sible to prevent 'Teedback" squeal.
