SV91M Operating & Maintenance Instructions

SECTION 5: OPERATION
WARNING!
STRONG MAGNETIC FIELDS ARE GENERATED.
REMOVE WATCHES BEFORE USE
ENSURE THAT THE FAN OPERATES CORRECTLY DURING
USE.(AFTER INITIAL WARM UP PERIOD). OPERATING PERIODS
IN EXCESS OF SPECIFIED DURATION WILL RESULT IN EXTERIOR
SURFACES BECOMING VERY HOT.
The SV91M degausser has been designed for simplicity of operation in that it consists
basically of a flat bed over which the magnetic media is passed. Control is via a single
on/off switch and indicator.
The illuminating on/off power switch is of the latching push button type which energises the
degaussing coil. The media to be erased should be held away from the degausser whilst it
is switched on. When switched on, the degauss indicator will also illuminate.
The media to be erased should be brought slowly towards the degausser's top surface.
Place the media on the top surface against the guide at the right or left hand edge. Slide
the media across the degausser in a slow and deliberate movement taking approximately
three seconds to traverse the top face.
5.1 Cassettes and Cartridges
Cassettes and cartridges must be turned through 90 degrees and a second pass made, the
media must be turned over and the process repeated, making a total of four passes to
ensure complete erasure.
5.2 Reels and Pancakes
The media in reel or pancake form to be erased should be brought slowly towards the top
surface. The media should be placed on the surface and rotated slowly and evenly taking
approximately five seconds to complete a revolution; then remove the media slowly from
the degausser before switching off. Reels with tape wider than 1/2" should be turned over
then subjected to a second pass.
It is recommended that the degausser is switched off between media erasure as this will
reduce the internal heating and increase the operation time.
