Charging the batteries
You can charge the lithium-ion battery either within the 
instrument itself or by means of the external charger 
recommended by us. Please observe the operating in
-
structions for the charger in this regard.
The handling of batteries, the charging process, and the 
meaning of LEDs and power indicators is described in 
detail in 
Chapter  Operation using batteries, page 3-4.
You should only use the batteries recom-
mended by us and the corresponding char-
ger. Any improper handling of the batteries 
and charger involves an explosion hazard.
