• Thelow battery indicator is displayed when 10-15% of
thebattery capacity is left.
• Beforebattery change, transfer all data from your FT40
topolarpersonaltrainer.com to avoid data loss. For more
informationsee Transfer Data.
• Excessiveuse of the backlight drains the battery more
rapidly.
• Incold conditions, the low battery indicator may appear,
butwill disappear when the temperature rises.

whenthe low battery indicator is displayed. Any alarms
setprior to the appearance of the low battery indicator
willremain active.

Changethe sealing ring of the battery cover every time you
changethe battery. You can purchase the sealing
ring/batterykits at well-equipped Polar retailers and
authorizedPolar Services. In the USA and Canada, the
additionalsealing rings are available at authorized Polar
