Warranty and Service Support 1-2General 4.2After Warranty Period After Warranty period, Motorola continues to support products in two ways. Firstly, Motorolas Radio Parts and Service Group (RPSG) offer a repair service to both end users and dealers at competitive prices. Secondly, RPSG supplies individual parts and modules that can be purchased by dealers who are technically capable of performing fault analysis and repair. To assist in this level of service, a Detailed Service Manual containing level 3 repair information may be purchased separately. 4.3Piece Parts Some replacement parts, spare parts, and/or product information can be ordered directly. If a complete Motorola part number is assigned to the part, it is available from Motorola Radio Parts and Service Group (RPSG). If a generic part is listed or only a part description is listed, the part is not normally available from Motorola. If a parts list is not included, this generally means that no user- serviceable parts are available for that kit or assembly. All orders for parts/information should include the complete Motorola identification number. All part orders should be directed to your local RPSG office. Head Office Motorola G.m.b.H. European Parts Department 65232 Taunusstein Germany 4.4Technical Support Motorola Product Services is available to assist the dealer/distributors in resolving any malfunctions which may be encountered. Initial contact should be by telephone whenever possible. When contacting Motorola Technical Support, be prepared with the product model number and the unit’s serial number. 4.5Associated Documentation Publication NumberDescription 68P64115B15GM1200E Detailed Service Manual (for Level 3 repair only) 68P64117B01Shared Mobile Radio Systems (SMR) using MPT1327 A System Integrators Cookbook 68P02900X57-AData Application Notes for 1200 Series Radios ELN4683A1200 Series Product Manual

Technical Specifications 1-6General 6.3Receiver 6.4Self-Quieting Frequencies Self-quieting frequencies are frequencies that are also generated by the radio and cause internal interference. On these frequencies the interference caused by the self-quieter spur is great enough that a radio will not meet its receiver sensitivity specification. The frequencies are: UHF 403.2, 420, 436.8 and 453.6MHz. VHF 151.2 and 168MHz.

Overview Maintenance2-1 1.0Overview This chapter explains, step by step, how to disassemble and assemble the radio, to transceiver board level. The chapter also contains a list of test equipment required to service the radio. 2.0Disassemble the Radio 2.1Remove the Control Head Figure 2-1 Control Head Removal. 1. Insert a small flat blade screw driver, or similar, in the recess between the control head and the transceiver (to minimise cosmetic damage to the radio cover start from the bottom side). 2. Press until the side of the control head releases and then repeat the operation on the opposite side of the radio. 3. Pull the control head away from the transceiver. 4. Remove the flex from the socket on the control head board. 2.2Remove the Top Cover Figure 2-2 Top Cover Removal. 1. Insert a small flat blade screw driver in the side recess of the radio chassis. 2. Lift the top cover over the chassis. 2 Recess Recess
Disassemble the Radio 2-2Maintenance 2.3Remove the Transceiver Board Figure 2-3 Transceiver Board Removal. 1.Remove the power and antenna connector retaining clips by inserting a small flat blade screw driver between the clip and the top of the chassis wall and gently prying the clip upwards. 2.Remove 13 screws from the transceiver board using a T8 TORX driver. 3.Carefully remove the transceiver board by rotating it out of the chassis: Slowly lift the board on the front edge, the side with the connector that mates with the control head, and pull gently toward the front of the radio. 2.4Disassemble the Control Head 1.To remove the printed circuit board from the control head front housing, first split control head into front and rear housing. In the front housing, insert a small blade screw driver in the side groove near the four protruding tabs of the printed circuit board. Remove the board from the control head front housing. 2.Remove the keypad from the control head housing by lifting up the rubber keypad. Care should be taken not to touch or get other contaminates on the conductive pads on the under side of the keypad or conductive contacts on the printed circuit board. 3.Remove the LCD module fom the LCD frame attached to the PCB.
