Section 5: Care & Maintenance
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
