User manual
• Batteries must be kept out of the reach of children. Do not leave batteries lying
around, as there is a risk that children or pets may swallow them.
• Batteries must not be dismantled, short-circuited or thrown into ames. Never
attempt to charge non-rechargeable batteries, as this may cause an explosion!

Preparation for mounting
• Check that you can receive a signal before mounting the clock. See "DCF signal reception"
for more information.
Assembly
• The clock is designed to be hung on a wall.
• Use the rear-mounted hook to hang the clock (not shown in the diagram).
Ensure that no existing cables or pipes (including water pipes) are damaged when
drilling mounting holes or securing screws.
• Secure the clock in place using a screw that protrudes a few millimetres from the wall.
• Refer to "Operation" for more information on using and setting up the wall clock.
• Hang the clock on the screw using the hook.
Operation
a) Inserting/replacing the battery
• Remove the used battery (if applicable).
• Before inserting the battery for the rst time, remove the locking pin (4) on the back of the
clock.
• Insert one 1.5 V AA battery (not included) into the battery compartment (5) on the back of the
clock, making sure that the positive (+) and negative (-) poles are correctly aligned.
• Change the battery if the clock fails to keep the time or the hands stop moving.
In principle, it is possible to operate the clock with a rechargeable battery. However,
rechargeable batteries have a lower voltage (rechargeable battery = 1.2 V,
conventional battery = 1.5 V) and a lower capacity, resulting in a shorter battery
life. If you wish to use rechargeable batteries, use special NiMH batteries with a low
self-discharge. For best results, we recommend that you use high-quality alkaline
batteries.
b) DCF signal reception
• To ensure optimal signal reception, do not place the clock next to other electronic devices,
cables, or metal objects. Some electronic devices may interfere with DCF reception.
• When you insert the battery, the clock will attempt to receive a DCF signal. The hands of
the clock will automatically move to 12:00. When a DCF signal is received, the hands will
automatically move to the correct time.
• This synchronisation process normally takes 2–5 minutes. The clock will display the correct
time when the DCF signal has been decoded (this can take up to 5 minutes).
It may take a few minutes for the clock to receive a DCF signal. Do not move the
clock during this time. Do not adjust any controls during this time.
Signal reception may be poor when the clock is placed near to double-glazed
windows, reinforced concrete, coated wallpapers or electronic devices, or when the
clock is placed in a cellar.
The hands will move several times while the time is being set.
If the correct time is still not displayed after 5 to 7 minutes, move the clock to a
different location and restart the DCF signal reception process manually. Press and
hold down the REC button (2) on the back of the clock for 3 seconds. The clock will
attempt to search for a time signal. (See "Manual DCF signal reception".)
Wait 2–5 minutes for the time to be displayed.
