Switching and Changing 
the Batteries
Merger LRFdevices are powered by 2 batteries: built-in Battery Pack and 
removable Battery Pack APS3.
1.
If there are two batteries in the device at the same time, two battery 
icons are displayed in the status bar (1 - built-in battery, 2 - removable 
battery). The device battery is displayed in white, inactive – in grey.
2.
When there is no removable battery in the device, only one icon for the 
built-in battery displays in white in the status bar.
3.
When both batteries are fully charged, the device is powered by the 
removable battery. If there is low removable battery level, the device 
will switch to the built-in battery.
4.
Battery charge level is displayed in % above the icon in the status bar 
while charging.
5.
It is possible to replace removable battery with device turned on when 
it is powered by built-in battery (the device will continue to work 
properly).
Attention! When installing a removable battery with a sufficient charge 
level, the device will automatically switch to it.
