The instrument fuse holder is located on the rear panel
(see Figure 2-3) and contains the line -protection fuse. The
following procedure may be used either to verify that the
proper fuse is installed or to install a replacement fuse .
INSTRUMENT COOLING
1. Unplug the power cord from the power -input source
(if plugged in ).
To prevent instrument damage from overheated com
ponents , adequate internal airflow must be maintained at
all times . Before turning on the power , first verify that both
the fan - exhaust holes on the rear panel and the air-intake
holes on the side panel are free from any obstructions to
airflow . After turning on the instrument , verify that the fan
is exhausting air.
2. Press in the fuse -holder cap and release it with a
slight counterclockwise rotation .
3. Pull the cap (with the attached fuse inside) out of
the fuse holder.
