4.2 Battery replacement
The battery capacity is continuously monitored by the electronics of the E2 / D2 and is
indicated by the number of bars (0…5 bars) in the battery symbol.
The batteries should be replaced when no bar is visible and the battery
symbol flashes. The E2 / D2 is still completely functional.
The batteries must be replaced when the additional message "/R
E$WW
" appears. The E2 / D2 is no longer operational.
CAUTION! Observe the battery type and polarity!
Damage can be caused if a different type of batteries is used or the batteries are incor-
rectly inserted during replacement.
ª Use only fresh batteries of the same type (LR6 - AA) when replacing.
