15.0 REPLACE THE BATTERIES
fig. 53
Watch: See fig. 53
All of the watch memory will be erased whenever the battery is changed.
We recommend that you take the watch to a jeweler or service center to replace the battery.
However, if you have the proper tools, you may try the following:
1. With a jewelers Phillips screwdriver remove the 4 screws and case back. Remember to save all watch parts as
you will need to re-install them.
2. Remove the cling film battery cover
3. Fit a stiff pin into the notch of the battery
retainer. Push it out and up to release the
retainer. Take care as this is delicate work. Lift
the spent battery out and recycle.
4. Insert a new CR2032 battery with the +
facing up. Take care to slide the battery up
and over the battery contact. Should you
crush the contact against the side, the watch
will not work and this is not covered by the
warranty.
5. Make sure that the rubber O-ring is still
in place. This O-ring must sit properly to
maintain water resistance. Refit the cling
film over the battery. Lastly, place the case
back to its original position and screw
it down.

fig. 54
Chest Strap: See fig. 54
1. With a coin in the cover slot, turn the small cover
arrow just past the strap arrow and the cover will
pop up for easy removal.
2. Be sure to slip the battery underneath the metal
contact arm.
3. Refit the battery cover, aligning the arrows, and
turn clockwise to close.
Note: If the chest strap fails to initialize [no signal],
reset it.
A. Remove the battery and turn it upside down.
B. With the positive side of the battery facing
down, lay it under the plus and on the minus
contacts inside the battery well. This will reset
the strap.
C. Re-install the battery with the positive side up.
When in Current Time Mode, press and hold ▼ for 5 seconds.
This puts the watch in a power saving mode. The display will
shut down but the time-keeping functions will continue to run.
