Exhibit 8: OEM Interface Manual©1999 Ericsson Inc. Page 4 of 111.1. MechanicalThe DM-20 module has no mechanical elements other that the main PCB assembly. All criticalelectronic components are shielded using sheet metal cans to prevent internal/externalelectromagnetic interference from degrading the module’s performance and to prevent themodule from interfering with other nearby devices. The following figure shows a typicalmounting configuration of the module with the main motherboard assembly. The module isplugged into the fixed mating connector and secured with four screws to the standoffcomponents.

Electrical PerformanceElectrical performance parameters are valid only when the terminating impedance at theoutput of the antenna connector exhibits a VSWR of less than 2:1 for all phase angles inthe frequency band of operation. High VSWR loads at the antenna connector adverselyaffect current consumption, linearity, and power efficiency of the module and mayprevent operation or cause internal damage.The RF performance of the DM-20 fully meets the following specifications:• IS-136 TDMA Cellular mode – Per IS-137 specification•553 AMPS Cellular mode – Per IS-19 specification
Exhibit 8: OEM Interface Manual©1999 Ericsson Inc. Page 6 of 11• CDPD Mode – Per Cellular Digital Packet Data (CDPD) System Specification, Release1.1, 19 January 1995 (CDPD will be supported in a future release of the DM20).1.2.2. Mobile Station Power ClassThe module is able to operate in several modes and different output power levels.Typical applications require output power levels similar to those in a handheld cellularphone (600-mW nominal) which is considered a power class IV unit for dual modeoperation. It is possible to increase the output power level to that of a class I unit (4 Wnominal) during the 5 second analog burst data mode. The table below shows thenominal output power levels (Effective Radiated Power, assuming an antenna systemgain of 1 dBd (3.15 dBi) [2.5 dBd (4.65 dBi) antenna gain with 1.5 dB cable loss)).Mobile Station Nominal Power LevelsMobile Station Power Level (dBW)0 1 2 3 4 5 6 7 8 9 10Class I 6 2 -2 -6 -10 -14 -18 -22 -22 -22 -22Class IV -2 -2 -2 -6 -10 -14 -18 -22 -27±3-32±4-37±5*Note: Output power levels maintained within range of +2 / -4 dB unless otherwisenotedPower levels 8-10 valid for digital mode only1.3.

At no time is the antenna to be located closer than 20 centimeters to a normallyoccupied location.2. At no time should an antenna system with greater than 1.0 dBd (3.15 dBi) gain beused with this module in any normally occupied area. The recommended antennasystem configuration is a standard automotive antenna with 2.5 dBd (4.65 dBi)antenna gain and 1.5 dB cable loss.3.2. Module OperationSafe and efficient use of this module requires a properly terminated antenna. DO NOToperate the module with a damaged or missing antenna, replace a damaged or missingantenna immediately otherwise damage to the module may result and could violateFCC regulations. DO NOT operate this device within 8 inches (20 cm) of a personunless proper shielding from the antenna is installed.3.3. Posted FacilitiesDo not operate this device where posted notices require wireless devices to be turnedoff.3.4. Electronic DevicesMost electronic equipment is shielded from RF signals. However, certain electronicequipment may not be shielded properly against RF signals.PacemakersThe Health Industries Manufacturers Association recommends that a minimumseparation of six (6) inches be maintained between a wireless transmitter and apacemaker to avoid potential interference with the pacemaker. These recommendationsare consistent with the independent research and recommendations of WirelessTechnology Research. Persons with Pacemakers should always keep theantenna/module more than 6 inches from their pacemaker when the module is on; ifyou have a reason to suspect that interference is taking place, turn off the moduleimmediately.

Your physician may be able to assist you in obtaining thisinformation.3.5. Blasting AreasTo avoid interfering with blasting operations, turn your module off when in a “blastingarea” or in areas posted: “Turn off two-way radio”. Obey all signs and instructions.3.6. Potentially Explosive AtmospheresTurn your module off when in any area with a potentially explosive atmosphere andobey all signs and instructions. Sparks in such areas could cause an explosion or fireresulting in bodily injury or even death.Areas with a potentially explosive atmosphere are often, but not always, clearlymarked. They include such areas as gasoline stations; below deck on boats; fuel orchemical storage or transfer facilities; vehicles using liquefied petroleum gas (such aspropane or butane); areas where the air contains chemicals or particles, such as graindust or metal powders; and any other area where you would normally be advised to turnoff your vehicle engine.3.7. VehiclesRF signals may affect improperly installed or inadequately shielded electronic systemsin motor vehicles. Check with the manufacturer or its representative regarding yourvehicle. You should also consult the manufacturer of any equipment that has beenadded to your vehicle.3.8. For Vehicles Equipped with an AirbagAn airbag inflates with a great force. Do not place objects including both installed orportable wireless equipment in the area over the airbag or in the airbag deploymentarea. If in-vehicle wireless equipment is improperly installed and the airbag inflates,serious injury could result.3.9. Responsible UseOEM Manufacturers providing telematic devices for vehicular use are encouraged toincorporate the following CTIA guidance for safe and responsible wireless phone useinto their user’s manuals:A Guide to Safe and Responsible Wireless Phone UseTENS OF MILLIONS OF PEOPLE IN THE U.S. TODAY TAKE ADVANTAGE OFTHE UNIQUE COMBINATION OF CONVENIENCE, SAFETY AND VALUE
Exhibit 8: OEM Interface Manual©1999 Ericsson Inc. Page 10 of 11DELIVERED BY THE WIRELESS TELEPHONE. QUITE SIMPLY, THEWIRELESS PHONE GIVES PEOPLE THE POWERFUL ABILITY TOCOMMUNICATE BY VOICE--ALMOST ANYWHERE, ANYTIME--WITH THEBOSS, WITH A CLIENT, WITH THE KIDS, WITH EMERGENCY PERSONNELOR EVEN WITH THE POLICE. EACH YEAR, AMERICANS MAKE BILLIONS OFCALLS FROM THEIR WIRELESS PHONES, AND THE NUMBERS ARERAPIDLY GROWING.But an important responsibility accompanies those benefits, one that every wirelessphone user must uphold. When driving a car, driving is your first responsibility. Awireless phone can be an invaluable tool, but good judgment must be exercised at alltimes while driving a motor vehicle--whether on the phone or not.The basic lessons are ones we all learned as teenagers. Driving requires alertness,caution and courtesy. It requires a heavy dose of basic common sense---keep your headup, keep your eyes on the road, check your mirrors frequently and watch out for otherdrivers. It requires obeying all traffic signs and signals and staying within the speedlimit. It means using seatbelts and requiring other passengers to do the same.But with wireless phone use, driving safely means a little more. This brochure is a callto wireless phone users everywhere to make safety their first priority when behind thewheel of a car. Wireless telecommunications is keeping us in touch, simplifying ourlives, protecting us in emergencies and providing opportunities to help others in need.When it comes to the use of wireless phones, safety is your most important call.Wireless Phone "Safety Tips"Below are safety tips to follow while driving and using a wireless phone, which shouldbe easy to remember.1. Get to know your wireless phone and its features such as speed dial and redial.Carefully read your instruction manual and learn to take advantage of valuablefeatures most phones offer, including automatic redial and memory. Also, work tomemorize the phone keypad so you can use the speed dial function without takingyour attention off the road.2. When available, use a hands free device. A number of hands free wireless phoneaccessories are readily available today. Whether you choose an installed mounteddevice for your wireless phone or a speaker phone accessory, take advantage ofthese devices if available to you.3. Position your wireless phone within easy reach. Make sure you place yourwireless phone within easy reach and where you can grab it without removing youreyes from the road. If you get an incoming call at an inconvenient time, if possible,let your voice mail answer it for you.4. Suspend conversations during hazardous driving conditions or situations. Letthe person you are speaking with know you are driving; if necessary, suspend thecall in heavy traffic or hazardous weather conditions. Rain, sleet, snow and ice can
Exhibit 8: OEM Interface Manual©1999 Ericsson Inc. Page 11 of 11be hazardous, but so is heavy traffic. As a driver, your first responsibility is to payattention to the road.5. Do not take notes or look up phone numbers while driving. If you are reading anaddress book or business card, or writing a "to do" list while driving a car, you arenot watching where you are going. It's common sense. Don't get caught in adangerous situation because you are reading or writing and not paying attention tothe road or nearby vehicles.6. Dial sensibly and assess the traffic; if possible, place calls when you are notmoving or before pulling into traffic. Try to plan your calls before you begin yourtrip or attempt to coincide your calls with times you may be stopped at a stop sign,red light or otherwise stationary. But if you need to dial while driving, follow thissimple tip--dial only a few numbers, check the road and your mirrors, thencontinue.7. Do not engage in stressful or emotional conversations that may be distracting.Stressful or emotional conversations and driving do not mix--they are distractingand even dangerous when you are behind the wheel of a car. Make people you aretalking with aware you are driving and if necessary, suspend conversations, whichhave the potential to divert your attention from the road.8. Use your wireless phone to call for help. Your wireless phone is one of the greatesttools you can own to protect yourself and your family in dangerous situations--withyour phone at your side, help is only three numbers away. Dial 9-1-1 or other localemergency number in the case of fire, traffic accident, road hazard or medicalemergency. Remember that it is a free call on your wireless phone!9. Use your wireless phone to help others in emergencies. Your wireless phoneprovides you a perfect opportunity to be a "Good Samaritan" in your community. Ifyou see an auto accident, crime in progress or other serious emergency where livesare in danger, call 9-1-1 or other local emergency number, as you would wantothers to do for you.10. Call roadside assistance or a special wireless non-emergency assistancenumber when necessary. Certain situations you encounter while driving mayrequire attention but are not urgent enough to merit a call for emergency services.But you still can use your wireless phone to lend a hand. If you see a broken-downvehicle posing no serious hazard, a broken traffic signal, a minor traffic accidentwhere no one appears injured or a vehicle you know to be stolen, call roadsideassistance or other special non-emergency wireless number.Careless, distracted individuals and people driving irresponsibly represent a hazard toeveryone on the road. Since 1984, the Cellular Telecommunications IndustryAssociation and the wireless industry have conducted educational outreach to informwireless phone users of their responsibilities as safe drivers and good citizens. As weapproach a new century, more and more of us will take advantage of the benefits ofwireless telephones. And, as we take to the roads, we all have a responsibility to drivesafely.
