REPlACINg ThE BATTERy
If the computer is giving erratic information, the computer or
hear rate strap battery may be running low on power (normally
accompanied by the low battery icon, Figure 15). Replace the
batteries whenever the computer malfunctions, or every 6
months. When purchasing new batteries, it is best to take the
old batteries with you. However, this is the generic description
for the proper battery:
CR2032, lithium cell, 3 volts
When the battery is removed, the computer automatically
resets function totals to Zero. After installing a new battery, you
can manually set your totals, but you must note those values
before removing the battery.
Replacing the Battery
Figure 6- Removing battery
cover
To replace the battery
1. Remove the computer from its base.
2. Identify the battery cover, with its deep
slot (a similar battery cover is found on
the back, or skin-side, or the heart rate
strap).
3. Insert a large coin into the slot and rotate
in a counter-clockwise direction about
one-quarter turn (Figure 16).
