3.1.3.1 Charge level and battery replacement
When the spy light is lit next to the power supply port on the radar, this indicates that the
system is powered: if it is not lit, this means that either the cable is not connected
correctly or that the battery needs recharged (less than 10V). The battery has a useful life
of around 12 hours. When the battery runs down the instrument must be switched off,
another battery connected, and the system can be started up again. A battery can be
completely recharged in around 3 hours with the appropriate battery charger (see Fig. 3-8
right). A software message on the PC informs the user of the battery charge level with a
BATT button (see Fig. 3-8 left), which changes color as follows:
¾ Green if the battery is fully charged
¾ Yellow if it is semi-charged
¾ Red if the battery needs recharged

NOTE
The control unit continuously draws current from the battery. To prevent
drain, unplug the battery when the unit is not in use.
