Section 5: Care & Maintenance
50
Overview
The Monitor 3 Air is a robust instrument designed to
withstand the rigors of SCUBA diving. However, you still
need to protect it from shock, extreme heat, chemical
attack, and tampering.
Even though the Monitor 3 Air’s material is tough and
durable, it is susceptible to chemical attack and scratches.
Chemical attack can be in the form of spray propellants,
gasoline fumes in your garage or boat, and alcohol. U.S.
Divers can replace scratched gauge faces. However, small
scratches naturally disappear underwater.
CAUTION: Never use aerosol sprays, including
silicone sprays, on or near the Monitor 3 Air. The
propellants may chemically attack the plastic,
causing the plastic case to crack.
Care Before the Dive
The Monitor 3 Air’s plastic housing is made of a shock
resistant resin. This housing protects the Monitor 3 Air
from the normal bumps that occur when diving. However,
the computer cannot withstand the impact of heavy objects,
such as weight belts or SCUBA cylinders. Impact from
heavy objects is the most common cause of computer
damage. When you set up your dive gear on a boat or the
beach, keep the Monitor 3 Air in its protective case until
you are ready to dive. Never leave the computer exposed
where someone could accidentally step on it or drop
something on it.
Care During the Dive
The most common damage inflicted on a computer while
underwater is scratches to the computer face. Avoid
inserting your hand into rocky holes while wearing the
computer on your wrist (i.e. reaching into a lobster hole to
capture the tasty crustacean!)
CAUTION: Scratches to the computer body or gauge
face are not covered by the Two-Year Limited
