SAFETY MTP700/MTP750 Portable Radios / Basic Service Manual Facilities To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.
MTP700/MTP750 Portable Radios / Basic Service Manual SAFETY Operational Warnings For Vehicles With An Air Bag Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air bags inflate with great force. If a portable radio is placed in the air bag deployment area and the air bag inflates, the radio may be propelled with great force and cause serious injury to occupants of the vehicle.
• Do not disassemble an FMRC Approved Product in any way that exposes the internal circuits of the unit. Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability and FM Approval labeling. Radios will not be “upgraded” to this capability and labeled in the field. A modification changes the unit’s hardware from its original design configuration.
FMRC Approved model. Do Not Substitute Options or Accessories The Motorola communications equipment certified by Factory Mutual is tested as a system and consists of the FM Approved portable, FM Approved battery, and FM Approved accessories or options, or both.
SCOPE & WARRANTY INFORMATION Scope Of This Manual This manual contains information necessary to identify and troubleshoot the MTP700/MTP750 Dim- etra Portable Radio at the board level. It also contains information on radio assembling, disassem- bling, and maintenance. Depending on the radio application, these radios are designed to work with Motorola’s Dimetra system or other TETRA compliant systems.
In instances where the product is covered under a "return for replacement" or "return for repair" war- ranty, a check of the product should be performed prior to shipping the unit back to Motorola. This is to ensure that the product has been correctly programmed or has not been subjected to damage outside the terms of the warranty.
Accessory Division (AAD). If no part number is assigned, the part is not normally available from Motorola. If a parts list is not included, this generally means that no user-serviceable parts are avail- able for that kit or assembly.
Aftermarket and Accessory Division (AAD). If no part number is assigned, 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.

Page 54
6 - 2 MTP700/MTP750 Portable Radios / Basic Service Manual MAINTENANCE Cleaning External Plastic Surfaces Apply the 0.5% detergent-water solution sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. Use a soft, absorbent, lintless cloth or tis- sue to remove the solution and dry the radio.
• Ground the working surface of the service bench to protect the CMOS device. We recommend using the Motorola Static Protection Assembly (part number 0180386A82), which includes a wrist strap, two ground cords, a table mat, and a floor mat.
When damaged parts are replaced, identical parts should be used. If the identical replacement part is not locally available, check the parts list for the proper Motorola part number and order the part from the nearest Motorola Radio Support Center. For details, please refer to relevant Support Depots on page 1-3 to 1-5.
