							Appendix B  Warranty, Service Support, and 
Replacement Parts
B.1 Scope of Manual
This manual is intended for use by service technicians familiar with similar types of equipment. It 
contains service information required for the equipment described and is current as of the printing 
date. Changes which occur after the printing date may be incorporated by a complete Manual revision 
or alternatively as additions.
B.2 Warranty
Motorola offers long term support for its products. This support includes full exchange and/or repair of 
the product during the warranty period, and service/ repair or spare parts support out of warranty. Any 
“return for exchange” or “return for repair” by an authorized Motorola Dealer must be accompanied by 
a Warranty Claim Form. Warranty Claim Forms are obtained by contacting an Authorized Motorola 
Dealer.
B.2.1 Warranty Period and Return Instructions
The terms and conditions of warranty are defined fully in the Motorola Dealer, Distributor, or Reseller 
contract. These conditions may change from time to time and the following notes are for guidance 
purposes only.
In instances where the product is covered under a “return for replacement” or “return for repair” 
warranty, 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.
B.2.2 After Warranty Period
After the Warranty period, Motorola continues to support its products in two ways. 
1.Motorolas Managed Technical Services (MTS) offers a repair service to both end users and 
dealers at competitive prices. 
2.MTS supplies individual parts and modules that can be purchased by dealers who are technically 
capable of performing fault analysis and repair. Note:
Before operating or testing these units, please read the Product Safety and RF Exposure
Compliance section in the front of this manual.
Note:
Only Motorola Service Centers or Approved Motorola Service Dealers can perform these
functions. Any tampering by non-authorized Motorola Service Centers voids the warranty of
your radio. To find out more about Motorola and its approved Service Centers, please visit

							B-2Warranty, Service Support, and Replacement Parts: Warranty
B.2.3 Piece 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’s Managed 
Technical Services (MTS). If no part number is assigned, the part is not normally available from 
Motorola. If the part number is appended with an asterisk, the part is serviceable by Motorola Depot 
only. 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. Request 
for help in identification of non-referenced spare parts should be directed to the Motorola’s local area 
representation. 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. 
Orders for replacement parts which are listed in the “Parts List” section of this manual, should be 
placed directly on Motorola’s local distribution organization or via Motorola Online (Extranet). 
						

							Appendix C  Repair Procedures and Techniques – 
General
Any rework or repair on Environmentally Preferred Products must be done using the appropriate 
lead-free solder wire and solder paste as stated in the following tables:
Parts Replacement and Substitution
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 Communications parts center listed in the “Piece Parts” section of this manual. Note
Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit
boards - examples shown below) were developed and assembled using environmentally
preferred components and solder assembly techniques that meet or exceed compliance
to the European Union’s ROHS and WEEE directives (Waste Electrical and Electronic
Equipment (WEEE) Directive 2002/96/EC and Restriction of Hazardous Substances
(ROHS) Directive 2002/95/EC). To maintain product compliance and reliability, use only
the Motorola specified parts in this manual.
For the identification of lead (Pb) free assemblies, all EPP products will carry the EPP
Marking, shown below, on the printed circuit board (PCB). This marking provides
information to those performing assembly, servicing and recycling operation on this
product, adhering to the JEDEC standard #97. The EPP Marking takes the form of a
label or marking on the PCB.

							C-2Repair Procedures and Techniques – General 
Rigid Circuit Boards
This family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not 
accessible, some special considerations are required when soldering and unsoldering components. 
The printed-through holes may interconnect multiple layers of the printed circuit. Therefore, exercise 
care to avoid pulling the plated circuit out of the hole.
When soldering near the connector pins: 
• Avoid accidentally getting solder in the connector. 
• Be careful not to form solder bridges between the connector pins. 
• Examine your work closely for shorts due to solder bridges.
Chip Components
Use the RLN4062 Hot-Air Repair Station for chip component replacement. Adjust the temperature 
control to 390 °C (735 °F), and adjust the airflow to a minimum setting. Airflow can vary due to 
component density.
•To remove a chip component: 
1.Use a hot-air hand piece and position the nozzle of the hand piece approximately 0.3 cm 
(1/8) above the component to be removed. 
2.Begin applying the hot air. Once the solder reflows, remove the component using a pair 
of tweezers. 
3.Using a solder wick and a soldering iron or a power desoldering station, remove the 
excess solder from the pads.
•To replace a chip component using a soldering iron: 
1.Select the appropriate micro-tipped soldering iron and apply fresh solder to one of the 
solder pads. 
2.Using a pair of tweezers, position the new chip component in place while heating the 
fresh solder. 
3.Once solder wicks onto the new component, remove the heat from the solder. 
4.Heat the remaining pad with the soldering iron and apply solder until it wicks to the 
component. If necessary, touch up the first side. All solder joints should be smooth and 
shiny.
•To replace a chip component using hot air:
1.Use the hot-air hand piece and reflow the solder on the solder pads to smooth it. 
2.Apply a drop of solder paste flux to each pad. 
3.Using a pair of tweezers, position the new component in place. 
4.Position the hot-air hand piece approximately 0.3 cm (1/8) above the component and 
begin applying heat. 
5.Once the solder wicks to the component, remove the heat and inspect the repair. All 
joints should be smooth and shiny. 
						

							Repair Procedures and Techniques – General C-3
Shields
Removing and replacing shields is recommended to be done with the Air Blower, 
BOSCH GHG 603 or equivalent.
•To remove the shield: 
1.Place the circuit board in the circuit board holder. 
2.Add solder paste flux around the base of the shield. 
3.Position the heat-focus head onto the shield. 
4.Turn on the heater and wait until the shield lifts off the circuit board. 
5.Once the shield is off, turn off the heat, and grab the part with a pair of tweezers.
6.Remove the circuit board from the circuit board holder.
•To replace the shield: 
1.Add solder to the shield if necessary, using a micro-tipped soldering iron. 
2.Next, rub the soldering iron tip along the edge of the shield to smooth out any excess 
solder. Use solder wick and a soldering iron to remove excess solder from the solder 
pads on the circuit board. 
3.Place the circuit board back in the circuit board holder. 
4.Place the shield on the circuit board using a pair of tweezers. 
5.Position the heat-focus head over the shield. 
6.Turn on the heater and wait for the solder to reflow.
7.Once complete, turn off the heat, raise the heat-focus head and wait approximately one 
minute for the part to cool. 
8.Remove the circuit board and inspect the repair. No cleaning should be necessary.
