environment. The ambient temperature range should remain between -40°C and
+45°C (-40°F and +113°F) for proper operation. Allow at least 12" (305 mm) of
clearance around the unit to permit an unimpeded access of convection air currents
for adequate heat dissipation. To permit the shortest possible cable length, place the
attenuator as close as possible to the transmitting equipment.

brackets down. Do not operate in any other manner.
The attenuator may stand free or may be secured to a bench or any convenient flat
surface. The front and rear face plates are made of heavier gauge material bent
outward 90° at the bottom to form mounting flanges. At each corner if these flanges
is a 3/8 inch x 15/32 inch elongated hole for use with suitable fasteners up to 3/8
inch. The holes are arranged in a 20-23/32 inch x 4-1/2 inch rectangle (526.3 x 114.3
mm). The front and rear face plates of the attenuator are also bent over on the top
to form convenient carrying handles. The following instructions are for mounting the
unit to a suitable surface.
1. Place the unit on a flat surface.
2. Insert the fasteners, up to 3/8 inch, through the bench and the holes.
3. Secure the bolts with nuts and lock washers.
