Batteries and Rechargeable Batteries
• Batteries/rechargeable batteries must be kept out of the reach of children.
• Do not leave batteries/rechargeable batteries lying around; there is a risk that they could be swallowed by
children or pets. If they are swallowed, consult a doctor immediately.
• Leaking or damaged normal/rechargeable batteries in contact with the skin can cause acid burns; there-
fore, use suitable safety gloves.
• Normal/rechargeable batteries may not be short-circuited, opened or thrown into fi re. There is a risk of
explosion!
• Do not recharge normal, non-rechargeable batteries, risk of explosion! Only charge rechargeable batteries
that are intended for this purpose; use a suitable battery charger.
• Check that the polarity is correct when inserting the battery/rechargeable battery (pay attention to plus/+
and minus/-).
Installation
Please proceed in the following order:
1. Attach the enclosed rubber washer onto the hand shaft.
2. Attach the clock movement from the back through the borehole to the clock-face and align it horizontally
with the suspension bracket facing upwards.
3. Place the washer above the hand shaft and tighten the clock movement with the middle hexagon nut.
In this process, make sure you don't tighten the nut too fi rmly to avoid twisting and damages.
4. Insert the hour hand fi rst and then the minute hand gently to the hand shaft and secure the minute hand
using the small knurled nut. If a second hand is used, the cap nut can be used to cover the hand shaft.
5. Finally insert the second hand into the hand shaft, if used.
6. Align all the hands of the clock to the 12:00 o'clock position.
7. Make sure the hands are aligned parallel to the clock-face so that they don't touch each other during
operation or rub against the clock-face.
8. Attach the pendulum weight onto the pendulum rod.
9. Unfasten the pendulum suspension bracket from the locking mechanism on the housing's rear and mount
the pendulum.

Inserting the Battery/Rechargeable Battery
• Insert a battery of type 1.5 V Mignon/AA into the battery compartment on the back of the casing, while
observing the correct polarity. The correct polarity is indicated in the battery compartment.
• Replacing the battery is necessary when the clock stops or the accuracy of movement decreases.
Setting the time
Set the time by turning the adjustment knob with the clock symbol on the back of the case. The adjustment
knob can be rotated in both directions here.
Maintenance and Cleaning
To clean the clock movement, a dry, soft and clean cloth is suffi cient.
Do not use any chemical cleaning agents, as they can corrode and discolour the plastic casing.
Disposal
a) Product
b) Normal and Rechargeable Batteries
As the end user, you are required by law (Battery Ordinance) to return all used batteries/rechargeable
batteries; disposal of them in the household waste is prohibited.
You can return your used batteries/rechargeable batteries free of charge to the offi cial collection points in
your municipality, in our stores, or anywhere where batteries or rechargeable batteries are sold.
You thereby fulfi l your statutory obligations and contribute to the protection of the environment.

The minute and second hands as well as the pendulum should not exceed the following dimen-
sions and weight:
Minute hand: max. 160 mm / 6 g
Second hand: max. 130 mm / 6g
The pendulum must be able to swing freely.
A rechargeable battery may be used, but due to the lower voltage output (rechargeable battery
= 1.2V, standard battery = 1.5V) and the lower capacity, the service life is shorter.
Electronic devices are recyclable waste materials and must not be disposed of in the household
waste!
Dispose of an unserviceable product in accordance with the relevant statutory regulations.
Remove the battery if there is one inserted and dispose of it separately from the product.
Batteries/rechargeable batteries containing harmful substances are marked with the follow-
ing symbols, to indicate that disposal in the household waste is forbidden. The symbols of the
relevant heavy metals are: Cd = Cadmium, Hg = Mercury, Pb = Lead.
