1.2 Operation And Maintainance Advice
Battery Operation
If and ´bAt´ are shown in the secondary display the battery has been
used up and needs to be replaced. The device will, however, operate
correctly for a certain amount of time. If ´bAt´ is shown in the upper display the
voltage is too low to operate the device; the battery has been completely used up.
Please note: We recommend to take out battery if device is not used for a
longer period of time!
Mains Operation With Power Supply
Warning:
When using a power supply please note that operating voltage
has to be 10.5 to 12 V DC.
Do not apply overvoltage!! Cheap 12V-power supplies often have excessive
no-load voltage.
We, therefore, recommend using regulated voltage power supplies.
Trouble-free operation is guaranteed by our power supply.
Prior to connecting the power supply to the mains make sure that the operating
voltage stated at the power supply is identical to the mains voltage.
