11 Battery/Charging

QUIETPRO is powered by a lithium-ion rechargeable battery.

11.1 Battery status

The typical battery capacity for continuous use is 40 hours. Battery capacity depends on a range of factors
such as usage pattern, noise environment, battery condition and temperature. The system allows you to check
the remaining capacity of the batteries. To do so, enter the menu and go to "Get Battery Status", then press
[CONFIRM]. It is also possible to request the battery status using the hot-key access.
TIP Hot-key for battery status: Press and hold [MENU] and [CONFIRM] for 3 seconds.
The battery status is presented by voice messages and indicator lights. The values below are valid for typical
conditions and lower battery capacities can be expected for older/used batteries. Note that for temperatures
below -20°C / -4°F, the battery capacity will be significantly lower than what is stated here.
Green steady light / "Battery level full"
Yellow steady light / "Battery level medium" Typically more than 12 hours left
Red steady light / "Battery level low"
Red blinking light / "Battery level very low" Unit should be charged

11.2 Low Battery Warning

The system will automatically give you a low battery warning when there is approximately 1 hour left of the
expected battery life. The warning will be repeated every 10 minutes. When the low battery warning is
announced, the unit should be charged immediately.

11.3 Automatic shutdown

To avoid full battery discharge, the system will shut down after 4 hours of inactivity (no button pressed).
A warning message will be given 10 minutes before shut down. To avoid automatic shutdown in this case,
press any button. Automatic shutdown can be disabled through the menu system under "Advanced System
Setup" - "Automatic Shutdown Options".

11.4 Charging the battery

Connect the charger to the control unit as showed in the illustration below. It takes approximately 4 hours to
charge a completely discharged battery. A yellow indicator light will be lit during charging and this will change
to green when the battery is fully charged. The unit should be turned off before connecting the charger.
