The
IQ-400
should be serviced every two years or after 300 dives (whichever
comes first) by an authorized dealer. This service will include a general opera-
tional check and battery replacement. The service requires special tools and
training. Therefore, it is advisable to contact an authorized TUSA dealer for
biennial service. Do not attempt to do any servicing that you are not trained
for.
The
IQ-400
will display a battery symbol as a warning when the power gets
too low. When this happens, the
IQ-400
should not be used until the battery
has been replaced (see also chapter 3.2.1 /Battery warning).
5.1 Maintenance
If left without care for an extended period, a thin film (often invisible to the
eye) will cover the unit. Much like the buildup on the glass of an aquarium,
this film is the result of organic contaminates found in both salt and fresh
water. Suntan oil,silicone spray and grease will speed up this process. As a
result of this buildup, moisture will be trapped next to the contacts and will
not allow your
IQ-400
to operate properly.
The water contacts can be cleaned with a soft pencil eraser.
IMPORTANT:
The
IQ-400
should be soaked, then thoroughly rinsed with
fresh water after each dive.
If the unit is mounted in a console boot, the entire console should be soaked in
fresh water and then rinsed. Make sure that all salt crystals and sand particles
have been flushed out of the console.
At the end of a dive trip, the
IQ-400
should be rinsed thoroughly and then
dried with a soft towel. If the unit is mounted into a console boot, the comput-
er unit will need to be removed from the console and cleaned before storage.
IMPORTANT:
When removing the computer from the console, check the bat-
tery compartment for possible moisture or water. This is easily done through
the transparent lid covering the compartment. DO NOT use the
IQ-400
if you
detect any moisture or water inside.
