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 16). 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.

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
