5. Battery and environmental notes
Keep batteries/rechargeable batteries out of reach of children.
Please observe the correct polarity, when inserting batteries/
rechargeable batteries into the unit.
Do not let batteries/rechargeable batteries lie around openly.
There is a risk of batteries being swallowed by children or pets. In
such a case, seek immediate medical care.
Leaking or damaged batteries/rechargeable batteries might cause
acid burns when getting into contact with skin, therefore, use
suitable protective gloves.
Make sure that batteries/rechargeable batteries are not short-
circuited or thrown into fire. There could be danger of explosion!
Never disassemble batteries/rechargeable batteries!
Batteries may not be re-charged. There could be danger of
explosion!
Remove batteries/rechargeable batteries to prevent damage to the
unit caused by leaky batteries/rechargeable batteries, if you do not
use the unit for longer periods of time (e.g. when storing).
Please note:
The base unit and remote sensor can also be operated with
rechargeable batteries. But due to the lower voltage (rechargeable
battery = 1.2 V, battery = 1.5 V) the range and operating time are
shorter. Furthermore, problems can occur when receiving DCF
time signals due to the lower voltage.
If problems occur when using rechargeable batteries (e.g. low
range, short operating period, poor DCF reception etc.), remove
rechargeable batteries and use common ones. We recommend
you to use high-quality "alkaline batteries" because their operating
life is longer than that of common zinc carbon batteries.

To switch on/off the pre-alarm function, proceed as follows:
• Briefly press the "
" button to display the alarm time.
• Briefly press the "
" button one more time, instead of "AL", "PRE-AL" and
time data will appear (e. g. "15 min" or "-- min", respectively).
• By pressing the " " button you can switch the pre-alarm on. The snow
flake left near the bell icon, indicating the activated pre-alarm, will appear
on the display.
• By pressing the " " button, you can switch the pre-alarm off, "-- min" will
appear on the bottom display line, the snow flake left near the bell icon will
disappear.
• Briefly pressing the "
" button will store the setting, the unit returns to the
normal time mode display.
Please note:
As a matter of course, you can also use the pre-alarm function
together with the "Snooze" function.
The "normal" daily alarm will be triggered again not before the next
day because the pre-alarm function has replaced the alarm clock
function! Do not fall asleep accidentally because there will be no
second alarm at the "normal" alarm time!
Switching the normal alarm off (e. g. during the weekend) will
automatically turn the pre-alarm off.
