1.8.1 Battery Replacement of the Wristop Computer
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 may 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
activated, the battery will need to be replaced.
Note: Heavy use of the electroluminescent backlight, the heart rate function, altimeter, and compass will significantly
reduce the life of the battery.
To replace the battery:
1. flip over 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 place to keep the Wristop Computer waterproof and place the battery compartment cover
back onto the backside of the Wristop Computer;
8. insert a coin back into the coin slot; and
