When used in mobile vehicles (for example public transport), the VideoJet X20 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 X20 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.
1. Connect the + (plus) line on the car battery to the BP terminal on the orange terminal block.
2. Connect the – (minus) line on the car battery to the GND terminal on the orange terminal block.
3. Now check that the connections are secure.
