Periodically check the SWR of the antennas and if this changes over time. Problems could occur more
often in poor weather conditions – rain, snow, strong wind etc.
b) Periodically (more often in a dusty environment, but at least once per year) clean the air filter
without opening the amplifier.
W A R N I N G
The air filter may be too dusty - be careful how you
clean it so that you DO NOT INHALE (BREATHE IN)
neither spill the dust over! Wrap it, for instance, in a
wet cloth before cleaning!
ACOM 700S has one air filter that is accessible from the rear - see Fig. 2.1. The filter is contained in an
externally mounted plastic enclosure. The cover of the enclosure, together with the filter itself, is
removed by gently pulling it away from the amplifier. Carefully clean the filter and cover from dust,
wash it with tap water and leave it to dry up before you mount it back.
Also clean (as much as possible from the outside, without opening the amplifier) all ventilation
apertures on the cover and the chassis, including the ones on the bottom. Finally put the filter back in
the filter enclosure cover and click the cover back in place.
C A U T I O N
Do not use solvents for cleaning – they can be dangerous to you,
as well as to the coating or the amplifier plastic parts.
In case of need, clean up the amplifier outside surfaces without opening it. Use a soft piece of cotton
cloth, slightly moistened with clean water.
7-2. Replacement of fuses
W A R N I N G HIGH VOLTAGE!
If replacement of fuses is necessary, first pull out the
amplifier mains plug from the mains outlet and wait for at
least 3 minutes!
The main fuses of the amplifier are located on the rear panel – Fig. 2-1.
The fuses must be of the fast type, European size 5x20mm, rated for 250VAC and rated as follows:
C A U T I O N
The fuses must be rated for a current corresponding to your
mains nominal voltage: 10A for operation from 200-240VAC.
Upon customer request:16А for operation from 100-120VAC
mains voltage. Use only standard fuses!
C A U T I O N
Never replace any fuses inside the amplifier without special
instructions from your dealer! Blown internal fuses can be a
symptom of a more serious problem, which should be resolved
beforehand. Unauthorized replacement of inside fuses infringes
the warranty conditions!
