1.7.1 Battery Replacement

The Wristop Computer operates on a three-volt lithium cell Type: CR 2430. The maximum life expectancy is
approximately 12-18 months.
A low battery-warning indicator is activated when 5-15 percent of the battery capacity is still available. When
this occurs we recommend replacement of the battery.
Extreme cold weather will activate the low battery-warning indicator. Though the indicator is activated, the
battery may not need to be replaced due to this condition. In temperatures above 10°C (50°F) and the low
battery warning indicator is activated, the battery will need to be replaced.
To replace the battery:
1. turn the Wristop Computer to view the backside;
2. insert a coin in the coin slot located on the battery compartment cover;
3. turn the coin counterclockwise to the open position marked on the back of the case;
4. remove the battery compartment cover;
5. remove the old cell from the battery compartment and ensure the o-ring and all surfaces are clean, dry and
not damaged. Do not stretch the o-ring;
6. place the new cell into the battery compartment (negative side down, positive side up);
7. ensure that the o-ring is in its place to keep the Wristop Computer waterproof. Place the battery compartment
cover back onto the backside of the Wristop Computer;
8. insert a coin back into the coin slot; and
9. turn the coin clockwise to the close position marked on the back of the case.
