battery interface allows the batteries to be hot-swapped
on the fly. When battery 1 voltage level is sensed to be
between 7.5vdc to 8.2vdc, the sensor will automatically
switch over to battery 2 without the loss of a single
observation. A third battery (not supplied) could then
replace battery 1, and the process would reverse.
When external power is applied, it has precedence
over the batteries, but will not charge the batteries.
Detailed information on the battery
LED s, batteries, and
battery charger can be found in Chapter 2 Interfacing,
Chapter 3 Installation, and Chapter 5 Safety.
