Changing Batteries
Avoid opening the sealed battery cover during the
guarantee period. We recommend that you have the
battery replaced by an authorized Polar Service Center.
They test your Polar FT40 for water resistance after
battery replacement and make a full periodic check.
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 FT40
to polarpersonaltrainer.com to avoid data loss. For more
information see Transfer Data.
• 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.
To change the battery yourself:
Change the sealing ring of the battery cover every time you
change the battery. 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 only. Keep the batteries away from
children. If swallowed, contact a doctor immediately.
Batteries should be disposed of properly according to local
regulations.
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 may decrease the capacity and thus the
lifetime of the battery.
