BATTERIES

The product uses 2 x CR2032 batteries, one for the watch

and another for the chest belt. Both are already installed.

The battery warnings are:

LOW BATTERY DESCRIPTION

ICON

Continuous ﬂashing: The watch

battery is low. Intermittent ﬂashing:

The watch battery is too low to run the

backlight

VIB * The battery is too low to run the

vibration alert

* Both the watch and vibration battery

is low

* The batteries typically last one year. The vibration feature

consumes battery life at a faster rate than the sound alarm.

We highly recommend that you contact the retailer or our

customer service department if you need to replace them.

To replace the watch battery:

1. Undo the screws and remove the back plate.

2. Using a thin blunt instrument, hook the release catch

and lift the clip.

3. Replace the old battery and then the battery clip.

4. Replace the back plate and screws.
