CHARGING
The device contains a rechargeable lithium polymer battery and can be successfully recharged over 600
times. A QTM-UAR10/QTM-UMR10 takes around 1 hour to fully charge. While charging, the LED will
remain red, and will turn off when charging is complete. The QTM-UAR10/QTM-UMR10 contains
circuitry that is designed to inhibit charging the battery at temperatures below 0°C (32°F) which could
cause irreparable damage to the unit and battery. Should a “frozen” unit be connected to the charge
cable, the unit will monitor the internal temperature and when it is above 0°C, will engage the battery
charge process.
