IntroductionRanger RP
Scales with a built-in battery can work independently from the mains for approximately 30 hours in normal operation. A prerequisite for this is that the background
lighting is switched off and that no peripheral devices are connected.
The device automatically switches to battery operation as soon as the mains supply
is
interrupted. When the mains supply is restored, the device automatically switches
back to mains operation.
The

rged (min. 4 hours). The charging period is extended if work is continued during
cha
rging. The battery is protected against overcharging.

e The battery’s charging capacity can be reduced under continuous mains operation.

To maintain the charging capacity, after a maximum of 4 weeks discharge the bat-
completely before recharging it.
