or humidity (e.g. bathrooms) or those with above-average levels of dust.
Operating temperature and operating humidity: 5 °C to 35 °C,
max. 85 % RH.
Always make sure that:
there is free circulation of air (do not place the device on shelves, on
a carpet, on a bed, or anywhere that obstructs the ventilation slots
and leave at least 10 cm clearance on all sides);

no fire hazards (e.g. burning candles) are placed on or near the
device;
no foreign bodies enter the device;
the device is not subject to major great temperature fluctuations as this
can cause condensation and short-circuits; if the device has been
exposed to strong temperature variations anyway, wait (approx. 2
hours) before turning it on, so it has reached the ambient temperature.
the device is not subjected to excessive shocks or vibrations.
Note on mains disconnection
The ON/OFF-FM/AUX button [2] located on the top of the device does
not fully disconnect the device from the mains. The device still consumes
electricity in standby mode. Disconnecting the device completely involves
removing the power plug from the wall outlet. For this reason, the device
should be positioned such as to enable unobstructed access to the wall
outlet so that the power plug can be pulled out immediately in an
emergency. To avoid the risk of fire, if the device is not going to be used
for an extended period (e.g. during holidays), it should always be
disconnected from the power socket. Always disconnect the device from
the power supply in stormy conditions.

SRW 250 A2 Alarm Clock Radio
Never open the housing of the device! Opening the housing could expose
you a fatal electric shock.
Power cable
Always hold the power cord by the plug. Never pull on the cable itself
and never hold the power cord with wet hands as this may cause a short
circuit or electric shock. Do not place the unit itself or any furniture or other
devices on the power cord and make sure that the cable does not get
trapped. Never tie knots in the cable and do not tie it to other cables. The
power cord should be positioned so that nobody can trip over it or be
obstructed by it. A damaged power cord can cause a fire or electric
shock. Check the power cord from time to time. If it is damaged, contact
the nearest authorised service centre or your dealer for a replacement.
Batteries
Insert the batteries with the correct polarity. Refer to the diagram inside the
battery compartment. Do not attempt to recharge the batteries and do not
throw batteries into a fire. Do not mix battery types (old and new or
carbon and alkaline, etc.). Remove the batteries if the device will not be in
use for an extended period. Improper use could cause explosions or
leaks.
