9. BATTERY REPLACEMENT
NOTE
It is advisable to contact an authorized Suunto representative for
battery replacement. It is imperative that the change is made in
a proper manner to avoid any leakage of water into the battery
compartment or computer.

is lost. Therefore, the no-fly time shown by the computer should
have reached zero or you must wait for 48 hours, or preferably

remain in the dive computer memory after the battery change. However, the clock
time and time alarm settings are lost. In the MIXED GAS mode, the gas mix settings
