6. TROUBLESHOOTING
Note
Where not indicated, voltages are measured versus the ground (i.e. the negative pole of the battery ).
Where not indicated, voltages are measured while the unit is switched on.
Where not indicated, the values to be measured can vary by about 2%.
WARNING
Be careful not to short-circuit any contacts while measuring voltages.
Batteries may explode if defective or damaged or disposed of in fire.
Do not short-circuit the batteries!
6.1. The device does not switch on
Check the integrity of the internal battery .
If the device is connected to the battery charger and the battery is disconnected or compromised, the display

Battery failure
If the battery charger is connected:
Check the battery charger:
– Make sure that the connector is fully inserted to the plug.
– Check the cable for visible damage.
Recharge battery
– Connect power cable to the device
– Check that the battery indicator on the display shows the correct charging phase
– When the charging is completed the battery indicator becomes green
6.2. The display remains black
Check that the flat connector of the display is not broken:
