Important Safety Information

Traffic Safety

  Do not use a hand-held phone while driving a vehicle.  If using a hand-
  held phone, park the vehicle before conversing.

  Always secure the phone in its holder; do not place the phone on the
  passenger seat or where it can break loose in a collision or sudden stop.

  The use of an alert device to operate a vehicle's lights or horn on public
  roads is not permitted.

  Remember, road safety always comes first!

Operating Environment

  Remember to follow any special regulations in force and always switch off
  your phone whenever its use is forbidden, or when it may cause interfer-
  ence or danger.

  Operation of any radio transmitting equipment, including cellular phones,
  may interfere with the functioning of inadequately protected medical
  devices. Consult a physician or the manufacturer of the medical device if
  you have any questions. Other electronic equipment may also be subject to
  interference.

  As with other mobile radio transmitting equipment, users are advised that
  for the satisfactory operation of the equipment and for the safety of
  personnel, it is recommended that the equipment should only be used in
  the normal operating position.

  Users are advised to switch off the phone while at a refueling point
  (service station). Users are reminded of the need to observe restrictions
  on the use of radio equipment in fuel depots (fuel storage and distribu-
  tion areas) chemical plants or where blasting operations are in progress.

  Do not store or carry flammable liquids, gases or explosive materials in
  the same compartment as a cellular phone or any of its parts or accessor-
  ies.

  Only qualified personnel should install or service the phone in a vehicle.
  Faulty installation or service may be dangerous and may invalidate any
  warranty which may apply to the unit.

  Electronic fuel injection systems, electronic anti-lock braking systems,
  electronic cruise control systems and other electronic systems can mal-
  function due to the lack of protection from radio signals. Check regular-
  ly that all cellular phone equipment in your vehicle is mounted and oper-
  ating properly.

  Switch off your cellular phone when in an aircraft.  The use of cellular
  phones in an aircraft may be dangerous to the operation of the aircraft,
  may disrupt the cellular network, and is illegal.

  Failure to observe these instructions may lead to suspension or denial
  of cellular phone services to the offender, or legal action or both.

Emergency Calls

IMPORTANT!

This phone, like any cellular phone, operates using radio signals, cellular
and land-line networks, as well as user-programmed functions which cannot
guarantee connection in all conditions.  Therefore, you should never rely
solely upon any cellular phone for essential communications (e.g., medical
emergencies).

Remember that to make or receive any calls, the phone must be switched on
and in a service area with adequate cellular signal strength.

Emergency calls may not be possible on all cellular phone networks or when
certain networks services and/or phone features are in use. Check with your
local cellular service providers.

To make an emergency call:

1.  If the phone is not on, switch it on by pressing and holding PWR.

2.  Press and hold CLR for several seconds to ready the phone for calls.

3.  Enter the emergency number for your present location (e.g., 911 or
    another official emergency number). Emergency numbers vary by location.

4.  Press SEND.

If certain features are in use (e.g., Keyguard), you may first need to turn
those features off before you can make an emergency call. Consult this doc-
ument and your local cellular service provider.

When making an emergency call, remember to give all the necessary informa-
tion as accurately as possible.  Remember that your cellular phone may be
the only means of communication at the scene of an accident - do not cut
off the call until given permission to do so.

Using This Guide

The cellular phone described in  this guide is approved for use in AMPS
networks.

A number of features included in this guide are called Network Services.
They are special services provided by cellular service providers.  Before
you can take advantage of any of these Network Services, you must subscribe
to the service(s) you require from your home service provider. You can then
activate these functions as described in this guide.

The manual activation commands for various network services are not
presented in this guide (e.g., using * and # characters for activating or
deactivating service).  The phone nevertheless is capable of handling
commands given in that form.  For these commands, please consult with your
service providers.
