Battery Replacement
We recommend having all the service done by an authorized Polar
Service Center. However, if you wish to change the battery
yourself, please follow these instructions.
Note: If you use your Polar heart rate monitor in water, the
rubber gasket seal that ensures water resistance may have to be
replaced and the unit should be tested for water resistance
every time the seal is broken. If an unauthorized service agent
services the heart rate monitor, or if you change the batteries
yourself, Polar guarantee does not cover damage or
consequential damage that may occur.
You will need the following:
Battery: CR 2430 3V
Dust-free pad that won't scratch the face of the wrist receiver
Small Phillips or standard head screwdriver
1. Put the unit on the clean, dust-free pad, face down.
2. Open the back by removing the four screws with the
screwdriver. Do not turn the unit upside down to remove
the back, doing so will spill out the contents.
3. Remove the back by pressing lightly on one of its corners, the
opposite corner will be raised enough to lift off the cover.
4. Leave the orange-colored gasket in its groove, or, if it is
separated, be careful not to twist it or damage it.
5. Remove the black plastic piezo case by gently inserting the tip
of the screwdriver into the slot at the upper right corner, and
gently pulling it in the direction of the wrist strap without
the buckle.

6. Take off the piezo case,
exposing the battery.
7. Remove the old battery, and
put in the new one with +
side up.
Do not handle the battery with
metal tweezers because this
could short it out.

Also, naturally occurring oils on your fingers will shorten battery
life and could weaken the contact. Make sure your hands are
freshly washed, and handle the battery only from its sides.
8. Replace the black plastic piezo case.
Holding it at a slight angle, insert the piezo case's two 'feet'
into the bottom slots in the metal case that also holds the battery.
Gently press down on the piezo case's top, then with the
screwdriver, push on the tab at the upper right corner while
applying downward pressure at the top to secure the piezo case into
the metal case (you will hear a click). This will lock it into place.
9. Make sure the gasket ring is not
damaged, and is fully in its
groove.
TIP: You'll notice the ring follows
the pattern of the groove. Just line
it up, and let it slip into place.

10. Wipe off finger prints on the module and clean the surface of
the back cover facing the sealing ring with a soft, lint free cloth.
11. Replace the back cover - The Polar text is in the upright position,
in respect to the buckle side of the wrist strap.
12. Replace screws, but do not fully tighten. Insert screws in
opposite corners, slightly tightening each one in a crosshatch
pattern - upper right, lower left, upper left, lower right and so on.
13. Push in the reset button with your screwdriver so that you see
all the characters on the face light up. Then press any other
button and you should see the Time of Day screen.
14. Wearing the Polar Polar coded transmitter, test functions by
activating the receiver, and re-set your settings.
If heart rate measurement does not start or all segments do not
appear to be operating normally, reset the receiver and test again.
If this does not resolve the problem, return the unit to an
authorized Polar Service Center.
