MTH500 Portable Radio Basic Service Manual - MAINTENANCE
CHAPTER 4
MAINTENANCE
Preventive Maintenance
This portable radio does not require a scheduled preventive maintenance program. How-
ever, periodic visual inspection is recommended. 
Inspection
Inspect the radio’s external surfaces. A detailed inspection of interior circuitry is not 
needed or recommended.
Cleaning
The following procedures describe the recommended cleaning agents and methods to be 
used when cleaning the external and internal surfaces of the radio. External surfaces 
should be cleaned whenever a periodic visual inspection reveals the presence of smudges, 
compound, or grime. Internal surfaces (circuit boards and components) should be cleaned 
only when the radio is disassembled for servicing or repair.
The only recommended agent for cleaning external radio surfaces is a 0.5% solution (one 
teaspoon of detergent per gallon of water) of mild dishwashing detergent in water. The 
internal surfaces should be cleaned only with isopropyl alcohol (70% by volume). 
						

							MAINTENANCE:  Safe Handling of CMOS Devices
28
Safe Handling of CMOS Devices
Complementary metal-oxide semiconductor (CMOS) devices are used in the radio. While 
the attributes of CMOS devices are many, their characteristics make them susceptible to 
damage by electrostatic or high voltage charges. Damage can be latent, resulting in failure 
occurring weeks or months later. Therefore, special precautions must be taken to prevent 
device damage during disassembly, troubleshooting, and repair. The following handling 
precautions are mandatory for CMOS circuits, and are especially important in low humid-
ity conditions.
•All CMOS devices must be stored or transported in conductive material so that all 
exposed leads are shorted together. CMOS devices must not be inserted into conven-
tional plastic “snow” or plastic trays of the type that are used for storage or transporta-
tion of other semiconductor devices.
•All CMOS devices must be placed on a grounded bench surface and the technician 
must also be grounded before handling the devices. This is done most effectively by 
having the technician wear a conductive wrist strap in series with a 100k

 resistor to 
ground.
•Do not wear nylon clothing while handling CMOS circuits.
•Do not insert or remove CMOS devices with power applied. Check all power supplies 
to be used for testing CMOS devices and be certain there are no voltage transients 
present.
•When straightening CMOS device leads, provide ground straps for the apparatus used.
•When soldering, use a grounded soldering iron.
•All power must be turned off in a system before printed circuit boards containing 
CMOS devices are inserted, removed, or soldered.
Level 1 and Level 2 Maintenance
This manual covers Level 1 and Level 2 Maintenance: at Level 1 maintenance you replace 
the radio and/or accessories and send the faulty unified chassis and/or accessories to a 
higher level of maintenance; at level 2 maintenance a faulty kit is replaced. 
Note: For Level 1 maintenance instructions refer to the information given in Chapter 2. 
For Level 2 maintenance also refer to Chapter 2, and the instructions given below.

Removing and Installing Battery Door and Battery
Recommended tools: no tools are required
To remove the battery door from the unit:
 (See Figure 2)
1.Place the unit facing down on the work area.
2.Press the battery door  release button, slide the door towards the bottom of the unit 
and lift it up from the unit.
To remove the battery:
(See Figure 3)
1.Press the battery fastening bridge toward the upper side of the unit.
2.Simultaneously, using other hand, release the battery from its chamber.
To install the battery:
1.Locate the battery so that the lower part (coloured silver) is touching the lower wall 
of the battery chamber.
2.Carefully press the battery down until it snaps into location.
To install the battery door:
1.Position the door on the unit over the battery so that the door release button is just 
above the battery fastening bridge.
2.Slide the door upward until the door snaps into location.
3.Verify that the door is aligned with the handset back housing.
