1.3 Radio Model Information
The model number and serial number are located on a label attached to the back of your radio. You 
can determine the RF output power, frequency band, protocols, and physical packages. The example 
below shows one mobile radio model number and its specific characteristics.

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. After completing 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.

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 20-pin and 40-pin connectors:

“Safe Handling of CMOS and LDMOS Devices”, Section 2.3.
2. If removing the transceiver board, the thermal pad material under the two Final stage devices 
(Q1402 and Q1403) on the radio chassis has been pulled up such that the radio chassis is 
exposed through the thermal pad, then the defective thermal pads must be removed and 
replaced. This is only true for the case when the Final stage...
