18. General Handling
Do not store the computer in hot and/or humid environments. The
pressure transducer is sensitive to both heat and humidity. If
impaired, it may cause display of incorrect altitude or depth data.
The IQ-850’s Liquid Crystal Display may darken if left in a hot
environment (such as on a car’s dashboard). It will return to normal
once allowed to cool; however, extensive exposure to heat may
shorten LCD life.
Other than for battery replacement, following the procedures outlined
in this manual, the IQ-850 is not to be disassembled by anyone other
than TUSA or its authorized dealers. Unauthorized disassembly will
violate the warranty.
If the IQ-850 does not appear to be functioning properly, in any
manner, do not use it to dive. Return it to your authorized TUSA
dealer for repair.
Rinse the IQ-850 thoroughly in fresh water following every dive.
Do not use cleansers, chemicals, or solvents to clean the IQ-850.
Use a soft cloth to gently wipe dirt or water stains from the screen.
Store the IQ-850 in a clean, dry location. After diving, wipe the
computer dry and store it in a location separate from other damp
items.
17. Units of Measurement
You can change the units of measurement between imperial/metric
for water depth and temperature of the IQ-850.
In DIVESET mode press and hold down both the B and C button for
six or more seconds. The computer will beep/vibrate once to notify you
that the units have changed.
Always verify the units of measure are correct before starting to
dive.
