1. CM-42 Transceiver Module Outline Drawing

1.1. Mechanical

The CM-42 module has no mechanical elements other that the main PCB assembly. All critical

electronic components are shielded using sheet metal lids and LCP frames to prevent

internal/external electromagnetic interference from degrading the module’s performance and to

prevent the module from interfering with other nearby devices. The following figure shows the

outline drawing for the module. The module is plugged into the fixed mating connector and

secured with eight screws to the standoff components.

Exhibit 8: OEM Interface Manual

1.2.1. Electrical Performance

Electrical performance parameters are valid only when the terminating impedance at the

output of the antenna connector exhibits a VSWR of less than 2:1 for all phase angles in

the frequency band of operation. High VSWR loads at the antenna connector adversely

affect current consumption, linearity, and power efficiency of the module and may

prevent operation or cause internal damage.

The RF performance of the CM-42 fully meets the following specifications:

• IS-2000 CDMA Cellular mode – Per EIA/TIA IS-98 specification

• IS-553 AMPS Cellular mode – Per IS-19 specification

Exhibit 8: OEM Interface Manual

1.2.2. Mobile Station Power Class

The CM-42 is able to operate in several modes and different output power levels. Applications may

require output power levels similar to those in a handheld cellular phone or higher levels commonly

required when in rural areas. The table below shows the nominal output power levels of the CM42.

Table 1: Power Consumption

1.3.1.1.1 Sleep Mode (Minimum DC Power consumption)

A power down mode is available in which the module is placed in a low power consumption state

under control of the host application. In this mode, the unit consumes approximately 110 uA of

current as measured from the VCC_5V supply input and 4 uA of current as measured from the

VCC_12V supply input. To activate this mode, the WAKE signal on pin 12 of the system

connector pulled to a logic level 1 which puts the module into the low power state. The module

will stay in the low power state until the WAKE signal is driven low by an external open collector

transistor in the application circuitry. Turning the external open collector transistor off will cause

the WAKE signal to float high and turn the module off. The WAKE line is tied to VCC_5V through

a 220kΩ pull-up resistor so the sink current in the external open collector transistor is minimal.

3. Safety & FCC Requirements

3.1. Warning: FCC RF Exposure Requirements

This module is approved for mobile operations only with respect to CFR 47 part 2.1091

and OEM integrators must seek separate approval to satisfy SAR requirements of

2.1093 for operation as a portable device.

Warning: Antenna Installation

1. At no time is the antenna to be located closer than 23 centimeters to a normally

occupied location.

2. At no time should an antenna system with greater than 1.0 dB gain be used with this

module in any normally occupied area. In an automotive configuration, an antenna

with a 2.5dB gain and a minimum 1.5 dB of cable loss should be used.

3.2. Module Operation

Safe and efficient use of this module requires a properly terminated antenna. DO NOT

operate the module with a damaged or missing antenna, replace a damaged or missing

antenna immediately otherwise damage to the module may result and could violate FCC

regulations. DO NOT operate this device within 8 inches of a person unless proper

shielding from the antenna is installed.

3.3. OEM Labeling

A label must be affixed to the outside of the end product into which the authorized

module is incorporated, with a statement similar to the following:

This device contains TX FCC ID: XXXXXX (where "XXXXXX" is the FCC ID of the

module).

3.4. Posted Facilities

Do not operate this device where posted notices require wireless devices to be turned

off.

3.5. Electronic Devices

Most electronic equipment is shielded from RF signals. However, certain electronic

equipment may not be shielded properly against RF signals.

Pacemakers

The Health Industries Manufacturers Association recommends that a minimum

separation of six (6) inches be maintained between a wireless transmitter and a

pacemaker to avoid potential interference with the pacemaker. These recommendations

are consistent with the independent research and recommendations of Wireless

Technology Research. Persons with Pacemakers should always keep the

antenna/module more than 6 inches from their pacemaker when the module is on; if

Exhibit 8: OEM Interface Manual

you have a reason to suspect that interference is taking place, turn off the module

immediately.

Hearing Aids

Some digital wireless devices may interfere with some hearing aids.

Other Medical Devices

If you use any other type of personal medical device in the presence of this transceiver,

consult the manufacturer of your device to determine if it is adequately shielded from

external RF energy. Your physician may be able to assist you in obtaining this

information.

3.6. Blasting Areas

To avoid interfering with blasting operations, turn your module off when in a “blasting

area” or in areas posted: “Turn off two-way radio”. Obey all signs and instructions.

3.7. Potentially Explosive Atmospheres

Turn your module off when in any area with a potentially explosive atmosphere and

obey all signs and instructions. Sparks in such areas could cause an explosion or fire

resulting in bodily injury or even death.

Areas with a potentially explosive atmosphere are often, but not always, clearly

marked. They include such areas as gasoline stations; below deck on boats; fuel or

chemical storage or transfer facilities; vehicles using liquefied 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.

3.8. 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.

3.9. For Vehicles Equipped with an Airbag

An airbag inflates with a great force. Do not place objects including both installed or

portable wireless equipment in the area over the airbag or in the airbag deployment

area. If in-vehicle wireless equipment is improperly installed and the airbag inflates,

serious injury could result.

3.10. Responsible Use

OEM Manufacturers providing telematic devices for vehicular use are encouraged to

incorporate the following CTIA guidance for safe and responsible wireless phone use

into their user’s manuals:

Exhibit 8: OEM Interface Manual

A Guide to Safe and Responsible Wireless Phone Use

TENS OF MILLIONS OF PEOPLE IN THE U.S. TODAY TAKE ADVANTAGE OF

THE UNIQUE COMBINATION OF CONVENIENCE, SAFETY AND VALUE

DELIVERED BY THE WIRELESS TELEPHONE. QUITE SIMPLY, THE

WIRELESS PHONE GIVES PEOPLE THE POWERFUL ABILITY TO

COMMUNICATE BY VOICE--ALMOST ANYWHERE, ANYTIME--WITH THE

BOSS, WITH A CLIENT, WITH THE KIDS, WITH EMERGENCY PERSONNEL

OR EVEN WITH THE POLICE. EACH YEAR, AMERICANS MAKE BILLIONS OF

CALLS FROM THEIR WIRELESS PHONES, AND THE NUMBERS ARE

RAPIDLY GROWING.

But an important responsibility accompanies those benefits, one that every wireless

phone user must uphold. When driving a car, driving is your first responsibility. A

wireless phone can be an invaluable tool, but good judgment must be exercised at all

times 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 head

up, keep your eyes on the road, check your mirrors frequently and watch out for other

drivers. It requires obeying all traffic signs and signals and staying within the speed

limit. 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 call

to wireless phone users everywhere to make safety their first priority when behind the

wheel of a car. Wireless telecommunications is keeping us in touch, simplifying our

lives, 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 should

be 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 valuable

features most phones offer, including automatic redial and memory. Also, work to

memorize the phone keypad so you can use the speed dial function without taking

your attention off the road.

2. When available, use a hands free device. A number of hands free wireless phone

accessories are readily available today. Whether you choose an installed mounted

device for your wireless phone or a speaker phone accessory, take advantage of

these devices if available to you.

3. Position your wireless phone within easy reach. Make sure you place your

wireless phone within easy reach and where you can grab it without removing your

eyes from the road. If you get an incoming call at an inconvenient time, if possible,

let your voice mail answer it for you.

Exhibit 8: OEM Interface Manual

4. Suspend conversations during hazardous driving conditions or situations. Let

the person you are speaking with know you are driving; if necessary, suspend the

call in heavy traffic or hazardous weather conditions. Rain, sleet, snow and ice can

be hazardous, but so is heavy traffic. As a driver, your first responsibility is to pay

attention to the road.

5. Do not take notes or look up phone numbers while driving. If you are reading an

address book or business card, or writing a "to do" list while driving a car, you are

not watching where you are going. It's common sense. Don't get caught in a

dangerous situation because you are reading or writing and not paying attention to

the road or nearby vehicles.

6. Dial sensibly and assess the traffic; if possible, place calls when you are not

moving or before pulling into traffic. Try to plan your calls before you begin your

trip 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 this

simple tip--dial only a few numbers, check the road and your mirrors, then

continue.

7. Do not engage in stressful or emotional conversations that may be distracting.

Stressful or emotional conversations and driving do not mix--they are distracting

and even dangerous when you are behind the wheel of a car. Make people you are

talking with aware you are driving and if necessary, suspend conversations, which

have 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 greatest

tools you can own to protect yourself and your family in dangerous situations--with

your phone at your side, help is only three numbers away. Dial 9-1-1 or other local

emergency number in the case of fire, traffic accident, road hazard or medical

emergency. Remember that it is a free call on your wireless phone!

9. Use your wireless phone to help others in emergencies. Your wireless phone

provides you a perfect opportunity to be a "Good Samaritan" in your community. If

you see an auto accident, crime in progress or other serious emergency where lives

are in danger, call 9-1-1 or other local emergency number, as you would want

others to do for you.

10. Call roadside assistance or a special wireless non-emergency assistance

number when necessary. Certain situations you encounter while driving may

require 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-down

vehicle posing no serious hazard, a broken traffic signal, a minor traffic accident

where no one appears injured or a vehicle you know to be stolen, call roadside

assistance or other special non-emergency wireless number.

Careless, distracted individuals and people driving irresponsibly represent a hazard to

everyone on the road. Since 1984, the Cellular Telecommunications Industry

Association and the wireless industry have conducted educational outreach to inform

wireless phone users of their responsibilities as safe drivers and good citizens. As we

Exhibit 8: OEM Interface Manual

approach a new century, more and more of us will take advantage of the benefits of

wireless telephones. And, as we take to the roads, we all have a responsibility to drive

safely.
