6.  CARE AND MAINTENANCE
Your Polar heart rate monitor is a high-tech instrument and should 
be treated with care. The suggestions below will help you fulfi ll the 
guarantee obligations.
Store your heart rate monitor in a cool, dry place. Do not store it 
in any kind of non-breathing material, such as a plastic bag or a 
sports bag if it is wet.
Service
During the two-year guarantee/warranty period, we recommend 
that your product is serviced by an authorized Polar Service Center 
only. The warranty does not cover damage or consequential damage 
caused by any service not authorized by Polar Electro. 
Taking Care of Your Polar Heart Rate Monitor
  • Keep your unit clean. Clean it with a mild soap and water 
    solution. Dry it carefully with a soft towel. Never use alcohol or 
    any abrasive material such as steel wool or cleaning chemicals. 
  • Never store the transmitter when it is wet. Sweat and moisture  
    can keep its electrodes wet and the transmitter activated, 
    which shorten the lifespan of the battery.
  • Keep your heart rate monitor out of extreme cold and heat. The  
    operating temperature is 14°F to 122°F / -10°C to +50°C.
  • Do not expose the heart rate monitor to direct sunlight for 
    extended periods, eg. by leaving it in a car.
  • Do not bend or stretch the transmitter. This may damage the 
 electrodes.
  • Do not dry the transmitter in any other way than with a towel. 
    Mishandling may damage the electrodes.
Transmitter Battery
The estimated average battery lifespan of the transmitter is 
2500 hours of use. If you suspect that the transmitter battery has 
discharged, contact your authorized Polar Service Center for a 
replacement transmitter. Polar recycles used transmitters. 
Wrist Unit Battery
The estimated average battery lifespan of the wrist unit is two years 
with normal use (1h/day, 7 days a week). The 
 indicates a low 
battery and that the battery should be replaced. Please note that 
excessive use of the alarm signal and the backlight (FS2c/FS3c) 
will drain the battery more rapidly. Do not open the wrist unit 
yourself. To ensure the water resistance properties and the use of 
qualifi ed components, the wrist unit battery should be replaced by 
an authorized Polar Service Center only. At the same time, a full 
periodic check of the Polar heart rate monitor will be done.
Note: 
  • In cold conditions, the low battery indicator may appear, 
    but the indicator is deactivated when you return to a normal 
 temperature.
  • Water resistance cannot be guaranteed after unauthorized 
 service.
  • The sounds and the backlight (FS2c/FS3c) are disabled when 
    the battery is low, in order to optimize the battery lifespan.
