2-2Maintenance 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. 2.3 Safe Handling of CMOS and LDMOS Devices...

Maintenance2-3 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: lAvoid accidentally getting solder in the connector....

Maintenance2-7 device may have been over-stressed as well. Handle the transceiver board per the procedure for “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...
