Changing Batteries
The FT40 and the WearLink
®
+ transmitter both
have a user changeable battery. To change the
battery yourself, please follow the instructions
carefully as instructed in chapter Change
Batteries Yourself.
Prior to changing the batteries, please note the
following:
• The low battery indicator is displayed when
only 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.
• 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.
• In cold conditions, the low battery indicator
may appear, but will disappear when the
temperature rises.
Change Batteries Yourself
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.
Keep the batteries away from children. If
swallowed, contact a doctor immediately.
Batteries should be properly disposed of
according to local regulations.
When handling a new, fully charged battery,
avoid clasp-like contact, i.e. simultaneous 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
lifetime of the battery.
