Changing Batteries
The FT80 training computer 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.
• 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.
