7. CARE AND MAINTENANCE
The Polar E40 heart rate monitor is a high-tech instrument and
should be treated with care. The suggestions below will help
fulfill the guarantee obligations, and allow you to enjoy the
product for many years to come.
Taking Care of the Polar Heart Rate Monitor
• Clean the transmitter regularly after use with a mild soap
and water solution. Dry it carefully with a soft towel. Keep
the wrist unit clean and wipe off any moisture. Never use
alcohol or any abrasive material such as steel wool or
cleaning chemicals.
• Do not dry the transmitter in any other way than with a
towel. Mishandling may damage the electrodes.
• Never store the transmitter wet. Sweat and moisture can
keep the electrodes wet and the transmitter activated;
shortening the battery life span.
• Store the heart rate monitor in a cool and dry place. Do not
store it in any kind of non-breathing material, such as a
plastic bag or a sports bag.
• Do not bend or stretch the transmitter. This may damage the
electrodes.
• Keep the 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, for example by leaving it in a car.
Service
During the two-year guarantee/warranty period we recommend
that you have service done by an authorized Polar Service
Center. The warranty does not cover damage or consequential
damage caused by service not authorized by Polar Electro.
Transmitter Battery
The estimated average battery life span of the transmitter is
2500 hours of use. If you suspect that the transmitter battery
has run out, contact your authorized Polar Service Center for a
replacement transmitter. Polar recycles used transmitters.
Wrist Unit Battery
The estimated average battery life span of the wrist unit is
mentioned in chapter 10 Technical Specifications. Please note
that excessive use of alarm signals drains the battery more
rapidly. The battery symbol indicates that the battery should
be replaced. Avoid opening the sealed battery cover during the
guarantee period. We recommend that you have the battery
replaced by an authorized Polar Service Center. At the same
time a full periodic check of the Polar heart rate monitor will be
done. If you choose to change the battery yourself, follow these
instructions.
Note: To ensure the maximum lifespan of the battery cover,
open it only when you need to change the battery. We
recommend that you change the sealing ring of the battery
cover every time you change the battery. Additional sealing
rings are available at authorized Polar Service Centers only.
