OPERATION
PREPARATION FOR USE
The 492 can be installed in any position that allows air
flow in the bottom and out the rear of the instrument . Feet
on the four corners allow ample clearance even if the
instrument is stacked with other instruments. A fan draws
air in through the bottom and expels air out the back.
Avoid locating the 492 where paper, plastic, or like
material might block the air intake.
The front panel cover for the 492 provides a dust-tight
seal . Use the cover to protect the front panel when storing
or transporting the instrument . The cover is also used to
store accessories and external waveguide mixers . The
cover is removed by first pulling up and in on the two
release latches then pulling up on the cover . The door to
the accessories compartment is unlatched by pressing the
latch to the side and lifting the cover.
The handle of the 492 can be positioned at several
angles to serve as a tilt stand , or it can be positioned at the
top rear of the instrument between the feet and the rear
panel so 492 instruments can be stacked . To position the
handle, press in at both pivot points and rotate the handle
to the desired position .
CAUTION
Removing or replacing the cabinet on the instrument
can be hazardous. The cabinet should only be
removed by qualified service personnel.
