Backup Power Supply
When used in mobile vehicles (for example public transport), the VideoJet X10 is usually
switched on when the vehicle is started with the ignition key. If the ignition is switched off,
the power supply to the unit is also stopped. To keep the internal clock running when the
engine is off, you can connect the VideoJet X10 directly to the car battery via the BP and GND
contacts. The correct time is crucial for evaluating local recordings.
CAUTION!
!
Connect only batteries with the following specification: 10 to 30 V DC, 50 Ah max.,
12/24 V continuous flow.
