Nokia 3620 User Guide

							[ 162 ] Users are advised to switch off the phone when 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 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 liquified petroleum gas (such as propane 
or butane); areas where the air contains chemicals or particles, such as 
grain, dust or metal powders; and any other area where you would normally 
be advised to turn off your vehicle engine.
Ve hicles
Only qualified personnel should service the phone, or install the phone in 
a vehicle. Faulty installation or service may be dangerous and may invalidate 
any warranty which may apply to the unit.
Check regularly that all wireless phone equipment in your vehicle is mounted 
and operating properly.
Do not store or carry flammable liquids, gases or explosive materials in the 
same compartment as the phone, its parts or enhancements.
For vehicles equipped with an air bag, remember that an air bag inflates 
with great force. Do not place objects, including both installed or portable 
wireless equipment in the area over the air bag or in the air bag deployment 
area. If in-vehicle wireless equipment is improperly installed and the air 
bag inflates, serious injury could result.
Using your phone while in the air is prohibited. Switch off your phone 
before boarding an aircraft. The use of wireless telephones in an aircraft 
may be dangerous to the operation of the aircraft, disrupt the wireless 
telephone network and may be illegal.
FCC regulations prohibit using your phone while in the air. Switch off your 
phone before boarding an aircraft. The use of wireless telephones in an 
aircraft may be dangerous to the operation of the aircraft, disrupt the 
wireless telephone network and may be illegal.
Failure to observe these instructions may lead to suspension or denial of 
telephone services to the offender, or legal action or both.

Emergency calls
Note: This phone, like any wireless phone, operates using radio 
signals, wireless, and landline networks as well as user-programed 
functions. Because of this, connections in all conditions cannot be 
guaranteed. Therefore you should never rely solely upon any wireless 
phone for essential communications (for example, medical 
emergencies).
Emergency calls may not be possible on all wireless phone networks or 
when certain network services and/or phone features are in use. Check 
with local service providers.
To make an emergency call:
1If the phone is not on, switch it on. Check for adequate signal strength.
Some networks may require that a valid SIM card is properly inserted 
in the phone.
2Press   as many times as needed (e.g. to exit a call, to exit a menu, 
etc.) to clear the display and ready the phone for calls. 
3Key in the emergency number for your present location (e.g. 911 or 
other official emergency number). Emergency numbers vary by location.
4Press the  key.
If certain features are in use, you may first need to turn those features off 
before you can make an emergency call. Consult this guide 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 wireless 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.

 CERTIFICATION INFORMATION (SAR)
THIS MODEL PHONE MEETS THE GOVERNMENTS REQUIREMENTS FOR 
EXPOSURE TO RADIO WAVES.
Your wireless phone is a radio transmitter and receiver. It is designed and 
manufactured not to exceed the emission limits for exposure to radio 
frequency (RF) energy set by the Federal Communications Commission of 
the U.S. Government. These limits are part of comprehensive guidelines 
and establish permitted levels of RF energy for the general population. The 
guidelines are based on standards that were developed by independent 
scientific organizations through periodic and thorough evaluation of 
scientific studies. The standards include a substantial safety margin 
designed to assure the safety of all persons, regardless of age and health.
The exposure standard for wireless mobile phones employs a unit of 
measurement known as the Specific Absorption Rate, or SAR. The SAR 
limit set by the FCC is 1.6W/kg.* Tests for SAR are conducted using 
standard operating positions accepted by the FCC with the phone 
transmitting at its highest certified power level in all tested frequency 
bands. Although the SAR is determined at the highest certified power 
level, the actual SAR level of the phone while operating can be well below 
the maximum value. This is because the phone is designed to operate at 
multiple power levels so as to use only the power required to reach the 
network. In general, the closer you are to a wireless base station antenna, 
the lower the power output. 
Before a phone model is available for sale to the public, it must be tested 
and certified to the FCC that it does not exceed the limit established by 
the government-adopted requirement for safe exposure. The tests are 
performed in positions and locations (for example, at the ear and worn on 
the body) as required by the FCC for each model. 
						

							[ 165 ]Reference information
The highest SAR value for the Nokia 3620 model phone as reported to the 
FCC when tested for use at the ear is 1.12 W/kg, and when worn on the 
body, as described in this user guide, is 1.28 W/kg. The highest SAR value 
for the Nokia 3660 model phone as reported to the FCC when tested for 
use at the ear is 0.77 W/kg, and when worn on the body, as described in 
this user guide, is 1.13 W/kg. (Body-worn measurements differ among phone 
models, depending upon available accessories and FCC requirements). 
While there may be differences between the SAR levels of various phones 
and at various positions, they all meet the government requirement. 
The FCC has granted an Equipment Authorization for this model phone 
with all reported SAR levels evaluated as in compliance with the FCC 
RF exposure guidelines. SAR information on this model phone is on file 
with the FCC and can be found under the Display Grant section of 
http://www.fcc.gov/oet/fccid
 after searching on FCC ID QFXNHM-10X 
for the Nokia 3620 model and FCC ID QFXNHL-8X for the Nokia 3660 
model.
For body worn operation, this phone has been tested and meets the FCC 
RF exposure guidelines for use with a carry case, belt clip, or holder that 
contains no metal and that positions the handset a minimum of 5/8-inch 
(1.5 cm) from the body. Use of other carry cases, belt clips, or holders may 
not ensure compliance with FCC RF exposure guidelines. If you do not use 
a body-worn accessory and are not holding the phone at the ear, position 
the handset a minimum of 5/8 inch (1.5 cm) from your body when the 
phone is switched on.
*In the United States and Canada, the SAR limit for mobile phones used 
by the public is 1.6 watts/kilogram (W/kg) averaged over one gram of 
tissue. The standard incorporates a substantial margin of safety to give 
additional protection for the public and to account for any variations in 
measurements. SAR values may vary depending on national reporting 
requirements and the network band. For SAR information in other regions 
please look under product information at www.nokia.com/us

Use enhancements safely
A few practical rules for enhancement operation:
Keep all enhancements out of the reach of small children.
When you disconnect the power cord of any enhancement, grasp and 
pull the plug, not the cord.
Check regularly that any vehicle-installed enhancements are 
mounted and are operating properly.
Installation of any complex car enhancements must be made by 
qualified personnel only.
Use only batteries, chargers, and enhancements that have been 
approved by the phone manufacturer. The use of any other types 
could invalidate any approval or warranty applying to the phone 
and could be dangerous.
