GTX/LCS 2000™ Mobile Radio Service Manual *6802945C70* 68P02945C70-O Motorola Inc. 8000 West Sunrise Boulevard Fort Lauderdale, Florida 33322-9934
Foreword The information contained in this manual relates to all GTX/LCS 2000™ radios, unless otherwise specified. Safety Information Airbag Warning Statement WARNING VEHICLES EQUIPPED WITH AIR BAGS An air bag inflates with great force. DO NOT place objects, including communication equipment, in the area over the air bag or in the air bag deployment area. If the communication equipment is improperly installed and the air bag inflates, this could cause serious injury. • Installation of vehicle communication equipment should be performed by a professional installer/technician qualified in the requirements for such installations. An air bag’s size, shape and deployment area can vary by vehicle make, model and front compartment configuration (e.g., bench seat vs. bucket seats). • Contact the vehicle manufacturer’s corporate headquarters, if necessary, for specific air bag information for the vehicle make, model and front compartment configuration involved in your communication equipment installation. FCC Safety Information The Federal Communications Commission (FCC), with its action in General Docket 79-144, March 13, 1985, has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC- regulated equipment. Motorola subscribes to the same safety standard for the use of its products. Proper opera- tion of this radio will result in user exposure substantially below FCC recommended limits. • DO NOT hold the radio with the antenna very close to, or touching, exposed parts of the body, especially the face, ears, or eyes, while transmitting. Hold the radio in a vertical position with the microphone two to three inches away from the lips. • DO NOT hold the transmit switch (PTT) on when not actually desiring to transmit. • DO NOT allow children to play with any radio equipment containing a transmitter. • DO NOT operate this equipment near electrical blasting caps or in an explosive atmosphere. Under certain conditions, radios can interfere with blasting operations. When you are in the vicinity of construction work, look for, and observe, signs cautioning against radio transmissions. If radio transmission is prohibited, you must not transmit until out of the area. Furthermore, you must turn off your radio to prevent any accidental transmission. • DO NOT replace or charge batteries in a hazardous atmosphere. Contact sparking may occur while installing or removing batteries and cause an explosion. • Turn the radio off when removing or installing a battery. Anyone intending to use a radio in a hazardous area is advised to become familiar with the subject of intrinsic safety and with Section 70 of the National Fire Code, which is commonly referred to as Article 500 of the National Electric Code. Use of anything but factory supplied components may affect the approval and safety of the radio. Likewise, it is advised that servicing should be performed only by qualified personnel who adhere to the following Factory Mutual (FM) required warning: WARNING Modification of FM approved intrinsically safe radios will negate Factory Mutual Research Corporation (FMRC) approval. Manual Revisions Changes which occur after this manual is printed are described in “FMRs.” These FMRs provide complete infor- mation on changes including pertinent parts listing data. Computer Software Copyrights The Motorola products described in this manual may include copyrighted Motorola computer programs stored in semiconductor memories or other media. Laws in the United States and other countries preserve for Motorola certain exclusive rights for copyrighted computer pro- grams, including the exclusive right to copy or reproduce in any form the copyrighted computer program.

REPLACEMENT PARTS ORDERING ORDERING INFORMATION When ordering replacement parts or equipment information, the complete identification number should be included. This applies to all components, kits, and chassis. If the component part number is not known, the order should include the number of the chassis or kit of which it is a part, and sufficient description of the desired component to identify it. Crystal and channel element orders should specify the crystal or channel element type number, crystal and car- rier frequency, and the model number in which the part is used. Orders for active filters, Vibrasender and Vibrasponder resonant reeds should specify type number and fre- quency, should identify the owner/operator of the communications system in which these items are to be used, and should include any serial numbers stamped on the components being replaced.
