3. TRAINING COMPUTER BATTERY
Charging Your Training Computer
The Polar RC3 GPS training computer has an internal, rechargable battery. Use the USB cable included in
the product set to charge the training computer via the USB connector on your computer. If you want to
plug the USB connector to a wall outlet, use a USB power adapter (not included in the product set).
1. Plug the micro USB connector into the USB port of the training
computer.
2. Plug the USB connector into the computer USB port. It is
recommended not to use USB hubs because a USB hub may not
supply enough power for the training computer.
Use a USB 2.0 compliant USB A-to-micro B cable included in the set
package. If you charge from a USB hub, for example, the charging time
might be prolonged.
If you use an AC adapter, make sure that the adapter is marked with
"output 5Vdc 0.5A - 2A max". Only use an AC adapter which is
adequately safety approved (marked with "LPS", "Limited Power
Supply" or "UL listed").
3. The charging animation appears on the display.
When you plug in the training computer for the first time, Windows
searches for drivers automatically. Wait for the driver search to
complete (it takes about one minute). Alternatively you can skip the
search. The charging animation / data transfer is disabled during the
search.
The battery will be 70-80% full after one hour of charging (if the
battery was low). Charging the battery fully takes up to one hour and a
half.
4. When the training computer is fully charged, Charging complete is
displayed. Disconnect the cable.
When you plug the micro USB connector into the USB port of the training computer, be careful not to
scratch the sealing surfaces of the back case. If sealing surface has deep scratches, it will cause loss of
IPx7 grade waterproof level.
After each time of using the USB port of the training computer, check visually that there is no hair, dust
or other dirt on the sealing surface area of the lid/back case. Gently wipe to remove any dirt. Do not use
any sharp tools or equipment for cleaning, which could cause which can cause scratches to the plastic
parts.
