Important safety information
Human exposure to electromagnetic fields
Calculations as per Annex A of EN62311:2008, show that the exposure levels with the supplied micro
stub antenna are within the recommended levels at distances exceeding 10.8cm (900MHz) and 5.58cm
(1800MHz). The T400 user should not be nearer to the antenna than these distances for longer than 6
minutes at any one time. If a higher gain antenna is used, this safe operating distance must be
increased by an appropriate amount.
Battery
Use the supplied Panasonic NiMH batteries. It is possible to use non-rechargeable AA alkaline cells in
special circumstances but replace with the correct batteries as soon as possible. Never leave alkaline
cells in the terminal for an extended period.
Power supply
Do not use any other power supply other than the one supplied with your terminal.
Failure to use either the supplied batteries or charger can damage the terminal and will invalidate the
warranty.
Operating environment
Make sure that no special regulations are in force that impose restrictions on the use of mobiles. Such
restrictions to mobiles would also apply to the T400 terminal.
Electronic devices
Most modern electronic equipment is shielded from radio frequency (RF) signals. However, certain
electronic equipment may not be shielded against the RF signals from your terminal.
Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 20 cm (8 inches) be maintained
between a hand-held wireless phone and a pacemaker. The same restriction should apply to the
antenna of the terminal. If you have any reason to suspect that interference is taking place, switch off
the terminal immediately.
Hearing aids
Some digital wireless phones may interfere with some hearing aids. In the event of such interference,
you may want to consult your service provider.
Other medical devices
Operation of any radio transmitting equipment, including cellular phones, may interfere with the
functionality of inadequately protected medical devices. Consult a physician or the manufacturer of the
medical device to determine if they are adequately shielded from external RF energy or if you have any
questions.
Switch off your terminal in health care facilities when any regulations 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.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor
vehicles (e.g. electronic fuel injection systems, electronic anti-skid (anti-lock) braking systems,
electronic speed control systems, air bag systems).
Check with the manufacturer or its representative regarding your vehicle. You should also consult the
manufacturer of any equipment that has been added to your vehicle.
