Transmitter:

•One 3V lithium battery: 1/2AA (K5546) and O-ring 2.00 mm x 2.00 mm (K5538)

•Battery storage time (shelf life): Up to three years

•Replacement: Every two years, or more often depending on dive activity

•Life expectancy at 20°C/68°F:

•0 dives/y –> 3 years

•400 dives/y –> 1 year

The following conditions have an effect on the expected battery lifetime:

•The length of the dives

•The conditions in which the unit is operated and stored (e.g. temperature/cold conditions). Below 10°C/50°F the expected battery lifetime is about 50-75% of that at 20°C/68°F

•The use of the backlight and audible alarms

•The use of the compass

•The quality of the battery. (Some lithium batteries may exhaust unexpectedly, which cannot be tested in advance)

•The time the dive computer has been stored until it gets to the customer. (The battery is installed in the unit at the factory)
