MAINTENANCE
1.0 Introduction
This chapter of the manual describes:
• preventive maintenance
• safe handling of CMOS devices
• repair procedures and techniques
2.0 Preventive Maintenance
The radios do not require a scheduled preventive maintenance program; however, periodic visual 
inspection and cleaning is recommended.
2.1 Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches 
are functional. It is not recommended to inspect the interior electronic circuitry.
2.2 Cleaning
The following procedures describe the recommended cleaning agents and the methods to be 
used when cleaning the external and internal surfaces of the radio. External surfaces include the 
front cover, housing assembly, and battery case. These surfaces should be cleaned whenever a 
periodic visual inspection reveals the presence of smudges, grease, and/or grime.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild 
dishwashing detergent in water. The only factory recommended liquid for cleaning the printed 
circuit boards and their components is isopropyl alcohol (100% by volume).
1.Cleaning External Plastic Surfaces
The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-
bristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or 
tissue should be used to remove the solution and dry the radio. Make sure that no water 
remains entrapped near the connectors, cracks, or crevices.
2.Cleaning Internal Circuit Boards and Components
Isopropyl alcohol may be applied with a stiff, non-metallic, short-bristled brush to dislodge 
embedded or caked materials located in hard-to-reach areas. The brush stroke should 
direct the dislodged material out and away from the inside of the radio. Make sure that 
controls or tunable components are not soaked with alcohol. Do not use high-pressure 
air to hasten the drying process since this could cause the liquid to collect in unwanted 
places. Upon completion of the cleaning process, use a soft, absorbent, lintless cloth to 
dry the area. Do not brush or apply any isopropyl alcohol to the frame, front cover, or 
back cover. NOTE
Internal surfaces should be cleaned only when the radio is disassembled for servicing or
repair.
CAUTION: The effects of certain chemicals and their vapors can have harmful results on 
certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided.

							2-2MAINTENANCE
3.0 Safe Handling of CMOS and LDMOS
Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios. 
CMOS characteristics make them susceptible to damage by electrostatic or high voltage 
charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, 
special precautions must be taken to prevent device damage during disassembly, 
troubleshooting, and repair. 
Handling precautions are mandatory for CMOS circuits and are especially important in low 
humidity conditions. DO NOT attempt to disassemble the radio without first referring to the CMOS 
CAUTION paragraph in the Disassembly and Reassembly section of the manual. 
4.0 General Repair Procedures and Techniques
Parts Replacement and Substitution
When damaged parts are replaced, identical parts should be used. If the identical replacement 
component is not locally available, check the parts list for the proper Motorola part number and 
order the component from the nearest Motorola Communications parts center listed in the “Piece 
Parts” section of this manual.
Rigid Circuit Boards
The 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 through-plated holes may interconnect multiple layers of the printed circuit. 
Therefore, care should be exercised to avoid pulling the plated circuit out of the hole.
When soldering near the 18-pin and 40-pin connectors: 
• avoid accidentally getting solder in the connector. 
• be careful not to form solder bridges between the connector pins 
• closely examine your work for shorts due to solder bridges. NOTE
Always use a fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage). 
						

							General Repair Procedures and Techniques2-3
Chip Components
Use either the RLN4062 Hot-Air Repair Station or the Motorola 0180381B45 Repair Station for 
chip component replacement. When using the 0180381B45 Repair Station, select the TJ-65 mini-
thermojet hand piece. On either unit, adjust the temperature control to 370 °C (700 °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. 
						

							2-4MAINTENANCE
Shields
Removing and replacing shields will be done with the R1070 station with the temperature control 
set to approximately 215°C (415°F) [230°C (445°F) maximum].
•To remove the shield: 
1.Place the circuit board in the R1070 circuit board holder. 
2.Select the proper heat focus head and attach it to the heater chimney. 
3.Add solder paste flux around the base of the shield. 
4.Position the shield under the heat-focus head. 
5.Lower the vacuum tip and attach it to the shield by turning on the vacuum pump. 
6.Lower the focus head until it is approximately 0.3 cm (1/8”) above the shield. 
7.Turn on the heater and wait until the shield lifts off the circuit board. 
8.Once the shield is off, turn off the heat, grab the part with a pair of tweezers, and turn off 
the vacuum pump. 
9.Remove the circuit board from the R1070 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 R1070 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 and lower it to approximately 0.3 cm (1/8”) 
above 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.
