Pressing a key sends a message to the microprocessor through the output (KEY_INT) line signifying that a key has been pressed. The microprocessor then samples the analog to digital voltages at the keypad row and keypad column, then makes a comparison with a map table to identify the key pressed.

Page 83 Low Band, 800 MHz, PassPort & 900 MHz Theory of Operation: 900 MHz Receiver 7-21 The IF signal applied to pin 3 of U351 is amplified, down-converted, filtered, and demodulated, to produce the recovered audio at pin 27 of U351. This IF IC is electronically programmable, and the amount of filtering (which is dependent on the radio channel spacing) is controlled by the microprocessor.

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”...
Page 93 Maintenance: General Repair Procedures and Techniques To remove a chip component: 1. Use a hot-air hand piece and position the nozzle of the hand piece approximately 1/8” (0.3 cm) above the component to be removed. 2. Begin applying the hot air. Once the solder reflows, remove the component using a pair of tweezers.

Page 95: Replacing The Circuit Board Fuse
Maintenance: Replacing the Circuit Board Fuse Replacing the Circuit Board Fuse In cases where the radio fails to turn on when power is applied, the circuit board fuse should always be checked as a probable cause of the failure. The radio must be disassembled to replace the fuses as described in the Basic Service Manual (see section Table 1-1.
