Additional Safety Information
Small Children
Your device and its enhancements may contain small parts. Keep them out of the reach of small children.

Operating Environment

Remember to follow any special regulations in force in any area, and always switch off your device when its use
is prohibited or when it may cause interference or danger. Use the device only in its normal operating positions.
Do not place credit cards or other magnetic storage media near the device, because information stored on
them may be erased.
SELV (Safety Extra Low Voltage) Compliance
Safety status of input/output connections comply to safety extra-low voltage (SELV) requirements.
Warning: To avoid electric shock, do not connect SELV circuits to telephone-network voltage (TNV) cir-
cuits. LAN ports contain SELV circuits, and PSTN ports contain TNV circuits. Some LAN and PSTN ports
both use RJ-45 (8P8C) connectors. Use caution when connecting cables.

Potentially Explosive Environments

Switch off your device when in any area with a potentially explosive atmosphere and obey all signs and instruc-
tions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Switch off
the device at refuelling points such as near gas pumps at service stations. Observe restrictions on the use of
radio equipment in fuel depots, storage, and distribution areas; chemical plants; or where blasting operations
are in progress. Areas with a potentially explosive atmosphere are often but not always clearly marked. They
include below deck on boats, chemical transfer or storage facilities, vehicles using liquefied petroleum gas, and
areas where the air contains chemicals or particles such as grain, dust, or metal powders.
Sensitive Electronic Equipment
The current state of research concludes that operational DECT phones normally do not adversely affect elec-
tronic equipment. Nevertheless, you should take some precautions if you want to operate DECT phones in the
immediate vicinity of such equipment like sensitive laboratory equipment. Always keep a minimum distance of
10 cm (3.94") to the equipment even when the phone is in standby.
Electrical Surges
We recommend the installment of an AC surge arrester in the AC outlet to which this device is connected to
avoid damage to the equipmen t caused by local strikes of lightening or other electrical surges.
