Putting the AC 3200 into operation
Putting the AC 3200 into
operation
Preparing the AC 3200 for use
You can set up the AC 3200 on an even surface or mount it into
a 19" rack.
Setting up the device
To ensure that the AC 3200 cannot slip on the surface on which
it is placed, four self-adhesive soft rubber feet are supplied.
CAUTION! Danger of heat damage to the devices!
During operation, the AC 3200 and the connected
transmitters produce considerable waste heat!
If this heat cannot dissipate, it can cause damage
to the devices!
The devices are equipped with fans to assist
dissipation of generated heat:
왘Make sure that the air vents 쐇on the sides of
the AC 3200 are not covered or blocked and
provide ducts of sufficient size or allow
sufficient space to ensure a free air flow
between the devices.
왘Regularily clean the air vents on the sides of
the AC 3200 with a soft brush.
왘In order to avoid heat accumulation, make sure
to install the AC 3200 as the uppermost device.
왘Never stack more than two devices directly one
above the other!
CAUTION! Risk of staining of surfaces!
Some surfaces have been treated with varnish,
polish or synthetics which might cause stains
when they come into contact with other
synthetics. Despite a thorough testing of the
synthetics used by us, we cannot rule out the
possibility of staining.
왘Do not place the AC 3200 on delicate surfaces.
