3. POWER SUPPLY
A main unit can generally be power supplied with a rechargeable battery pack DC2033 in the battery compartment.
The external battery carrier DC2032 , for 6 or 3 type AA batteries, can also be used to increase the usage time of the unit.
Also, in low or high temperatures (below 5°C or above 45°C), where the NiMH batteries do not have full capacity, a main
unit can be continuously power supplied in a power supply holder DC2068 with a mains adapter DC2061
NOTICE! See below concerning the mandatory mains adapter DC2061 , which is included in the package at delivery of the
power supply/holder DC2068 !
When the energy in the battery is low, voice messages announce that it is time to charge the batteries or, when appropriate,
to change batteries.
! The message “ BATTERY LOW ” indicates that the energy in the battery is low and you should charge or change battery
as soon as possible.
! The message “ BATTERY EMPTY ” indicates that the energy in the battery is very close to empty and the unit will
automatically switch off!
