Safety

General Safety

The modem is designed for and intended to be used in fixed and mobile applications. “Fixed” means that the device is physically

secured at one location and is not able to be easily moved to another location. “Mobile” means that the device is designed to be

used in other than fixed locations.

Caution: Maintain a separation distance of at least 20 cm (8 inches) between the transmitter’s antenna

and the body of the user or nearby persons. The Modem is not designed for or intended to be used in

portable applications within 20 cm. (8 inches) of the body of the user.

RF Interference Issues

It is important to follow any special regulations regarding the use of radio equipment due in particular to the possibility of radio

frequency, RF, interference. Please follow the safety advice given below carefully.

●Switch OFF your MultiModem when in an aircraft. The use of cellular telephones in an aircraft may endanger the

operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe this instruction may lead to

suspension or denial of cellular telephone services to the offender, or legal action or both.

●Switch OFF your MultiModem when around gasoline or diesel-fuel pumps and before filling your vehicle with fuel.

●Switch OFF your MultiModem in hospitals and any other place where medical equipment may be in use.

●Respect restrictions on the use of radio equipment in fuel depots, chemical plants or where blasting operations are in

progress.

●There may be a hazard associated with the operation of your MultiModem close to inadequately protected personal

medical devices such as hearing aids and pacemakers. Consult the manufacturers of the medical device to determine

if it is adequately protected.

●Operation of your MultiModem close to other electronic equipment may also cause interference if the equipment is

inadequately protected. Observe any warning signs and manufacturers’ recommendations.

Vehicle Safety

●Do not use your MultiModem while driving.

●Respect national regulations on the use of cellular telephones in vehicles. Road safety always comes first.

●If incorrectly installed in a vehicle, the operation of MultiModem telephone could interfere with the correct functioning of

vehicle electronics. To avoid such problems, be sure that qualified personnel have performed the installation.

Verification of the protection of vehicle electronics should be part of the installation.

●The use of an alert device to operate a vehicle’s lights or horn on public roads is not permitted.

Maintenance of the Cellular MultiModem

Your cellular MultiModem is the product of advanced engineering, design, and craftsmanship and should be treated with care.

The suggestions below will help you to enjoy this product for many years.

●Do not expose the MultiModem to any extreme environment where the temperature or humidity is high.

●Do not attempt to disassemble the MultiModem. There are no user serviceable parts inside.

●Do not expose the MultiModem to water, rain, or spilled beverages. It is not waterproof.

●Do not abuse your MultiModem by dropping, knocking, or violently shaking it. Rough handling can damage it.

●Do not place the MultiModem alongside computer discs, credit or travel cards, or other magnetic media. The

information contained on discs or cards may be affected by the phone.

●The use of accessories not authorized by Multi-Tech or not compliant with Multi-Tech’s accessory specifications may

invalidate the warranty of the MultiModem.

●In the unlikely event of a fault in the MultiModem, contact Multi-Tech Technical Support.

Handling Precautions

All devices must be handled with certain precautions to avoid damage due to the accumulation of static charge. Although input

protection circuitry has been incorporated into the devices to minimize the effect of this static build up, proper precautions should

be taken to avoid exposure to electrostatic discharge during handling and mounting.

Cellular Information

Antenna System for Cellular Devices

The cellular performance is completely dependent on the implementation and antenna design. The integration of the antenna

system into the product is a critical part of the design process; therefore, it is essential to consider it early so the performance is

not compromised. If changes are made to the certified antenna system of the MultiModem, then recertification will be required

by specific network carriers such as Sprint. The Antenna System is defined as the UFL connection point from the MultiModem

to the specified cable specifications and specified antenna specifications.

PTCRB Requirements for the Antenna

There cannot be any alteration to the authorized antenna system. The antenna system must maintain the same specifications.

The antenna must be the same type, with similar in-band and out-of-band radiation patterns.

FCC Requirements for the Antenna

The antenna gain, including cable loss, for the radio you are incorporating into your product design must not exceed the

requirements at 850 MHz and 1900 MHz as specified by the FCC grant for mobile operations and fixed mounted operations as

defined in 2.1091 and 1.1307 of the FCC rules for satisfying RF exposure compliance. The antenna used for transmitting must

be installed to provide a separation distance of at least 20cm from all persons and must not transmit simultaneously with any

other antenna transmitters. User and installers must be provided with antenna installation instructions and transmitter operating

conditions to satisfying RF exposure compliance.

Chapter 2 – Installation

Connect the Antenna, Serial and Power Cables

1. Connect a suitable antenna to the ANT connector on the back of the unit, refer to Cellular Information in Chapter 1 for

antenna specifications.

2. Connect a serial cable to the RS232 connector on the back of the unit and connect the other end of the cable to the

serial port on your PC.

3. Depending on the power source, connect either the power supply module with the appropriate blade or a customer-

supplied DC power cable. If you are using the power supply module, remove the protective shipping cover. Attach the

appropriate interchangeable blade piece to the power supply module.

4. Screw-on the power lead from the power supply module to the power connection on the modem. Now, plug the power

supply into your power source.

For customer-supplied DC Power

●Screw-on a customer-supplied DC power cable to the power connector on the modem.

●Then attach the two wires at the other end of the DC power cable to a DC fuse/terminal block.

●Connect the red wire to the "+" (positive) terminal and the black wire to the "–" (negative) terminal. Be sure the

GND connection is correct.

Warning: Over-voltage protection is provided on the device. To ensure complete protection, you may want to add

additional filtering to the DC input.

Note: For automotive application: according to the type of application, you can use permanent “+” or key-switched “+”

source. Connect the power supply to its source (for example, in a mobile situation, to the vehicle’s DC

fuse/terminal block).

Powering Down and Hardware Resetting a MTCBA-C1X Modem

It is recommended to follow the following shutdown sequence, when possible, prior to a hardware

reset or turning off of power to the modem.

The shutdown sequence informs the network that the mobile station is going offline, and saves

critical data to the module‘s non-volatile memory (flash).

AT+CFUN=0 (issue this command)

+WIND:10 (Wait for this response from the modem)

Modem is now ready to be powered off or reset.

If you do not see the +WIND:10 response, you may need to activate the unsolicited message by

using the command AT+WUSLMSK=00020000,0

Chapter 2 - Installation

10 Multi-Tech Systems, Inc. MultiModem CDMA User Guide

Optional Mounting

Before you mount your modem to a permanent surface, ensure that you have a strong enough (average) signal, refer to Verify

Signal Strength in Chapter 3.

Once you have verified that you have a good signal, you can panel mount your modem with the screws spaced according to

the measurement shown below.

Note: Use, for example, two 6-3 self-tapping screws 5/8” in length to mount the unit.
