QUICK USE GUIDE
WARNING!
When your A1’s battery reaches the end of its lifetime, it is recommended to be replaced by an authorized
SCUBAPRO service center.
To locate your nearest service center, visit http://www.scubapro.com/where-to-buy
Do not open your A1 or try to replace the battery yourself!
Opening the housing or the metal caseback of your A1 will void your warranty.
Changing the battery must be done with particular care in order to prevent water from seeping into the dive computer.
The A1’s warranty does not cover damages due to the improper placement
of the battery, or the incorrect closing of the caseback.
Your A1 is powered by a CR2450 battery
❚Your A1 is powered by a non-rechargeable coin cell battery.
❚Always check the battery level before each dive.
❚If the battery warning appears, have the battery replaced.
