Prior to changing the battery, please note the following:
• The low battery indicator is displayed when 10-15% of the battery capacity is left.
• Before battery change, transfer all data from your RCX5 to polarpersonaltrainer.com to avoid data loss. For
more information, see Transfer Data (page 26).
• Excessive use of the backlight drains the battery more rapidly.
• In cold conditions, the low battery indicator may appear, but will disappear when the temperature rises.
• The backlight and sound are automatically turned off when the low battery indicator is displayed. Any
alarms set prior to the appearance of the low battery indicator will remain active.
Keep the batteries away from children. If swallowed, contact a doctor immediately. Batteries should be disposed of
properly according to local regulations.
Change Batteries Yourself
To change the batteries of the training computer and transmitter yourself, carefully follow the instructions
below:
When changing the battery, make sure the sealing ring is not damaged, in which case you should replace
it with a new one. You can purchase the sealing ring/battery kits at well-equipped Polar retailers and
authorized Polar Services. In the USA and Canada, the additional sealing rings are available at authorized
Polar Service Centers. In the USA the sealing ring/battery kits are also available at www.shoppolar.com.
When handling a new, fully charged battery, avoid clasp-like contact, i.e. simultaneously from both sides,
with metal or electrically conducting tools, like tweezers. This may short circuit the battery, causing it to
discharge more rapidly. Typically, short circuiting does not damage the battery, but it may decrease the
capacity and the lifetime of the battery.
1. Open the battery cover with a coin by turning it
from CLOSE to OPEN.
2.
• When changing wrist unit battery (2a),
remove the battery cover and lift the battery
out carefully with a suitable sized small rigid
stick or bar, for instance, a toothpick or small
screwdriver. However, prefer a non-metal tool
for wrenching the battery out. Be careful not
to damage the metal sound element (*) or the
grooves. Insert a new battery with the positive
(+) side outwards.
• When changing transmitter battery (2b),
place the battery inside the cover with the
positive (+) side facing the cover.
3. Replace the old sealing ring with a new one (if
available), fitting it snugly in the cover groove to
ensure water resistance.
4. Put the cover back on and turn it clockwise to
CLOSE.
5. Re-enter the basic settings if you changed the
wrist unit batteries.
