P ONE & MEMORY SETUP
Do not set up phone while in an Intrinsically Safe environment.
Before charging or using your handset, you may want to install a SIM card to allow the handset to
connect to a mobile telephone network and make phone calls. You may also want to install a 2
Gigabyte microSD card to increase the amount of the memory available on the device. A SIM card
from a network operator that operates a GSM network will allow phone calls and data transport
around the world. This handset will not operate on CDMA networks.
Remove Silicon Jacket. Insert the SIM Card & optional Micro SD Card
1. Place handset with battery facing up, and loosen the four
battery cover screws by turning them counter-clockwise
with the special Airo screwdriver supplied with your
handset. Do not overly loosen the screws. The screws are
designed to stay in the cover when loose.)
2. Detach the battery cover from your handset.
3. Open the SIM cage by inserting your thumbnail into the
slot and carefully pushing away from you, until you hear
and feel the cage door click, then carefully lift the edge.
4. If you have a MicroSD memory card, open the SD cage
by inserting your thumbnail into the slot and pushing to
the right lightly until you until you hear and feel the cage
door “pop,” then lift the edge. If you do not have an SD
card, skip to step #6 on the next page.

GENERAL SAFETY INFORMATION
Radio Frequency (RF) Energy Emission
Your device is a low power radio transmitter and receiver. When it is ON, it receives and sends RF
signals. In August 1996, the Federal Communications Commissions FCC) adopted RF exposure
guidelines with safely levels for handheld wireless phones. Those guidelines are consistent with the
safety standards previously set by both U.S. and International standards bodies:
• ANSI C95.1 1992) • NCRP Report 86 1986) • ICNIRP 1996)
Those standards were based on comprehensive and periodic evaluations of the relevant scientific
literature. For example, over 120 scientists, engineers, and physicians from universities, government
health agencies, and industry reviewed the available body of research to develop the ANSI Standard
C951). Your device has been equipped with internal shielding to minimize stray emissions of RF energy.
However, using your device can still be limited in the some instances.
When Boarding an Aircraft
•FCC regulations prohibit using your device while in the air. Turn all of your wireless modules off
before taking off.
•Most airline regulations prohibit the on-board use of portable PCs and all other portable
electronic devices that could potentially emit stray RF energy), particularly during take-offs and
landings, to prevent any possible interference with the reception of signals by airborne
electronic navigational devices.
•Always request and obtain prior consent and approval of an authorized airline
representative before using your device aboard an aircraft.
•Always follow the instructions of the airline representative whenever using your device
aboard an aircraft, to prevent any possible interference with airborne electronic equipment.
When Inside ospitals and Other ealth Care Facilities
•Turn the wireless modules off in healthcare facilities when any regulations posted in these areas
instruct you to do so. Hospitals or healthcare facilities may be using equipment that could be
sensitive to external RF energy.
•Always comply with posted prohibitions of the use of RF- emitting devices in hospitals and other
medical facilities. Failure to follow such directives could result in the interference with
medical equipment and/or devices.

Airo Wireless I-Safe™ 28 User Guide ARW-DPU-0001-01) 20
When Around Pacemakers
The Health Industry Manufacturers Association recommends that a minimum separation of six
6”) must be maintained between your device and a pacemaker to avoid potential
interference with the pacemaker. These recommendations are consistent with the independent
research and recommendations of Wireless Technology Research. Never come closer than six
6”) to a person with a heart pacemaker implant when using this device. Failure to do so could
result in interference with the function of the pacemaker.
When Wearing a Pacemaker
•You should ALWAYS keep the device more than six inches from their pacemaker when
the device is turned ON.
•You should not carry the device in a breast pocket.
•If you have any reason to suspect that interference is taking place, turn all of your wireless
modules OFF immediately.
When Wearing earing 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 or call the
customer service line to discuss alternatives).
When Using Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device
to determine if they are adequately shielded from external RF energy.
Your physician may be able to assist you in obtaining this information.
When in Motor Vehicles
•RF signals may affect improperly installed or inadequately shielded electronic systems in motor
vehicles. 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.
•Never use your device while driving an automobile or any other moving vehicle. Always
pull out of traffic and come to a stop in a legally permissible and safe location before
using your device. Failure to do so could result in serious bodily injury traffic accidents.
•Never place your device on the passenger seat or any place else in the car where it can
become a projectile during a collision or stop.
•An air bag inflates with great force. DO NOT place objects, including both installed and
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.
•Talking on your phone while driving is extremely dangerous, and is illegal in some states.
Remember, safety comes first. Check the laws and regulations on the use of phones in the
areas where you drive. Always obey them. If you must use the phone function while
driving, please:
