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 o 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.
Medical devices
Operation of any equipment emitting radio frequency signals may interfere with the functionality of
inadequately shielded medical devices. Consult a physician or the manufacturer of the medical device
to determine if they are adequately shielded from external radio frequency (RF) energy or if you have
any other questions concerning this topic. Switch o your device in health care facilities when signs
posted in these areas instruct you to do so. Hospitals or health care facilities may be using equipment
that could be sensitive to external RF energy.

Admin and Installation Guide M900 Important Information
Implanted medical devices
Manufacturers of medical devices recommend that a minimum distance should be maintained
between a wireless device and an implanted medical device, such as pacemakers or cardioverter
defibrillators, to avoid potential interference with the medical device. Persons who have such devices
should:
• Always keep the wireless device more than 100 centimeters (39 inches) from the medical device when the
wireless device is turned on.
• Not carry the wireless device in a breast pocket.
• Hold the wireless device to the ear opposite the medical device to minimize the potential for inter-ference.
• Turn the wireless device o immediately if there is any reason to suspect that interference is taking place.
• Read and follow the directions of the medical device‘s manufacturer.
• If you have any questions about using your wireless device with an implanted medical device, consult your
health care provider.
SELV (Safety Extra Low Voltage) Compliance
Safety status of Input/Output connections comply with SELV requirements.
Potentially explosive environments
Switch o your device when in any area with a potentially explosive atmosphere and obey all signs
and instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or
even death. Switch o 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
aect electronic 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 equipment caused by local strikes of lightening or other electrical
surges.
Cleaning
Use an anti-static cloth. Please avoid water and liquid or solid cleaning products as they might
damage the surface or internal electronics of the base, charger, and handset.

Important safety information
Follow all instructions and warnings in the user manual, and on the equipment to prevent accidents.
WARNING
Fire, electric shock, or other injury may result if you do not observe the following safety precautions:
• Do not use in or near a bathtub, sink, swimming pool, wet basement, or other water.
• Do not use this or any cordless telephone in the vicinity of a gas leak.
• Do not use in environments subject to explosion hazards, such as auto paint shops.
• Do not use near medical equipment or if you have a pacemaker.
• Unplug from wall outlet before cleaning.
• To prevent overheating, do not block slots and openings in the cabinet or the back or bottom of
equipment. Do not place equipment on beds, sofas, rugs, or other surfaces that generate fibers.
• To prevent overheating, do not place near or over a radiator or in a cabinet without
properventilation.
• To reduce the risk of fire, use only 26 AWG or larger UL-listed or CSA-certified telecommunication
line cord.
• Operate using the power source indicated on the marking label. If you are unsure about the type of
power supply to your home or business, consult your power company.
• Do not place objects on the power cord. Do not step on the power cord.
• To prevent exposure to dangerous voltage, do not push objects through cabinet slots.
• To reduce the risk of electric shock, do not disassemble equipment or open parts other than
specified access doors. Opening or removing parts may expose you to dangerous voltage or other
risks. Incorrect reassembly can cause electric shock when equipment is subsequently used.
• Do not overload wall outlets and extension cords.
• Unplug equipment and contact qualified service if any of the following has occurred:
◦Power supply cord or plug has been damaged or frayed.
◦Liquid has been spilled on or in the equipment.
◦Equipment has been exposed to rain or water.
◦Equipment does not work normally even when the operating instructions are followed. Adjust
only those controls referred to in the operating instructions. Improper adjustment of other
controls may result in damage and may require extensive work by an authorized service
center.

◦Equipment has been dropped and damaged.
◦Equipment has exhibited a distinct change in performance.
• Do not put the handset of the telephone next to your ear when the handset is not in normal talk
mode.
• Radio signals transmitted between the handset and base may cause interference with hearing
aids.
• The cord may contain lead, a chemical known to the State of California to cause birth defects or
other reproductive harm. Wash hands after handling.
• Install the product at a minimum distance of 100 cm (39") to persons and animals.
Installation guidelines
Follow all warnings and instructions.
• Do not install equipment near a bath tub, sink, or shower.
• Operate the equipment using only the power source indicated on the marking label. If you are
unsure of the power supply to your home or business, consult with your power company.
• To avoid interference to nearby appliances, do not place base of the phone on or near a television,
VCR, or microwave oven.
• Do not expose the equipment to direct sunlight.
• Do not place equipment on an unstable cart, stand, or table.
• Adjust only those controls referred to in the operating instructions. Improper adjustment of other
controls may result in damage and may require extensive work to restore equipment to normal
operation.
• The location of the device should be close to a continuous power outlet (an AC outlet that does not
have a switch to interrupt power).
• Keep the device away from sources of electrical noise such as motors or fluorescent lighting.
NOTICE
To avoid damage to the equipment, observe the following precautions:
• Do not expose to water, rain, or moisture.
• Place securely on a stable surface.
• To avoid damage during an electrical storm, equipment should be plugged into a surge protector.
Cordless telephone privacy
Cordless telephones are radio devices. Communications between the handset and base of your
cordless telephone are accomplished by means of radio waves which are broadcast over the open
airways. Because of the inherent physical properties of radio waves, your communications can be
received by radio receiving devices other than your own cordless telephone unit. Consequently, any
communications using your cordless telephone may not be private.
