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.
Note: Heavy use of the electroluminescent backlight, altimeter, and compass will significantly reduce the life of
the battery.
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.
Note: Battery replacement should be performed with extreme care so as to ensure the Wristop Computer
continues to remain waterproof.It is the operator's responsibility to take due care to ensure that the Wristop
Computer remains waterproof.
After every battery replacement, it is necessary to calibrate the magnetic sensor. Details on performing this
process are found in Calibrating the Compass section of this manual.
