Chapter 1 - Introduction 1-3
• When connecting the communicator to a PC 
or printer, please refer to the User’s Guides of 
those devices for detailed safety instructions.
•The infrared beam of the communicator may 
interfere with the functioning of other 
infrared devices that are not IrDA certified. Do 
not point the infrared beam at anyone’s eye.
•Consult aircraft personnel as to whether you 
may use the communicator interface applica-
tions in an aircraft. However, always switch 
off the phone interface when in an aircraft. 
The use of cellular telephones in an aircraft 
may be dangerous to the operation of the 
aircraft, disrupt the cellular network and is 
illegal.
• Failure to observe these instructions may lead 
to suspension or denial of cellular telephone 
services to the offender, or legal action or 
both.
Emergency calls
The Nokia 9000 Communicator, like any cellular 
phone, operates using radio signals, cellular and 
landline 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 com-
munications (e.g. medical emergencies).
Remember, to make or receive any calls the com-
municator’s phone interface must be switched 
on and in a service area with adequate cellular 
signal strength.
Emergency calls may not be possible on all cellu-
lar phone networks or when certain network 
services and/or phone features are in use. Check 
with local cellular service providers.
Some networks may require that a valid SIM card 
is properly inserted in the communicator.
To make an emergency call: 
If the device cover is open, close the cover.
If the phone interface is not on, switch it on 
(press the   key).
Press and hold the   key for several seconds 
to ready the phone interface for calls. If there 
is an active data or fax call, drop the call first 
by pressing the   key.
Key in the emergency number for your 
present location (e.g., 112 or other official 
emergency number). Emergency numbers 
vary by location.
Press the   key.
If certain features are in use (call barring, fixed 
dialling, closed user group, system lock, keypad 
lock, etc.), you may first need to turn those fea-
tures off before you can make an emergency call. 
Consult this document and your local cellular 
service provider.
When making an emergency call, remember to 
give all the necessary information 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.
