The TUSA
IQ-400
diving computer is a sophisticated
precision instrument. Remember to treat it as such! It
has been designed to withstand the rigors of scuba
diving. It can be installed in a durable thermoplastic
console boot and its display can be protected by a
replaceable display shield.
The user should wash and rinse the unit in fresh
water after every use. Protect it from shocks, extreme
heat or direct sunlight and chemical attack. The
IQ-
400
cannot withstand the impact of heavy objects
like scuba cylinders, nor chemicals like acetone and
alcohols (ethanol, isopropanol).
