Recommendations and safety
instructions
For safety reasons, never put the handset in the base station
without the battery inserted or without the lid on the battery
compartment as this could cause an electric shock.
To avoid damaging your handset/base, only use certified
rechargeable batteries NiMH 1.2 V 650 mAh, never use
non-rechargeable batteries. Insert the batteries in the
handset/base battery compartment respecting polarity.
Only use the power unit supplied and connect it to the
electricity mains in accordance with the installation
instructions in this user manual and the details on the sticker
regarding voltage, electrical current and frequency. As a
precaution if there is a risk of danger, the power plug can be
pulled out to disconnect the 230 volt power supply.
Therefore the sockets should be near the device and easily
accessible.
Do not install your DECT telephone in a damp environment,
such as a bathroom, washroom, kitchen etc, and not within
1.50 meters of a source of water or outside. This device is
designed for use in temperatures of between 5 °C and 45 °C.
Your DECT telephone has a range of approx. 50 meters
indoors and up to 300 meters outdoors. The range can be
affected by the proximity of metal objects, such as a
television and electrical devices.
Zones without reception may appear owing to elements in
the building. This can cause brief interruptions in the
conversation, caused by faulty transmission. Areas without
reception may appear because of construction peculiarities.
This may cause brief interruptions in conversation, due to
poor transmission.
Certain medical equipment and highly-sensitive machines or
security systems may be affected by the transmission power
of the telephone. In these cases we recommend adhering to
the safety information.
In regions greatly affected by electrical storms we
recommend that you protect your telephone circuit with a
special fixture for excess voltage.
