Safety and Precautions Packing for Return for Repair
All electronics assemblies must be
properly packed in ESD protective
packing for transport, to prevent
physical and ESD damage. Use of
non-ESD protective packing for
return for repair or service will
automatically invalidate the
warranty.
Environmental
The temperature and humidity ranges shown
in the specifications for these products must
not be exceeded.
This equipment must not be installed in an
area that is subject to a corrosive atmosphere,
excessive moisture or may allow water or other
liquids to come into contact with the unit or its
external connections.
The filler material used for packing
for return for repair must be
antistatic or static dissipative, as
this may come into contact with
exposed connectors, wiring, or
PCB assemblies. The use of non-
conductive filler material may
cause damage to the electronic
assemblies reducing their
operational life, or even destroying
them, and it will automatically
invalidate the warranty.
The unit must be installed away
from large metallic structures.
Unpacking and Handling
This equipment is heavy. Please
lift and handle with care to avoid
strain or drop injuries. Advice on packing the product for return can
be provided by Application Solutions Limited.
!

The equipment should be unpacked and
inspected immediately on receipt. If damage
has occurred please advise your carrier or
supplier.

Fault Finding and Maintenance
Fault Finding
The most likely failure of the ANT04 is through corrosion of the external connection, and this should be
thoroughly checked if there is any suspicion that the unit is not passing the required strength of RF
signal.
Maintenance
There is no relevant maintenance action to be carried out.
