1. Unless otherwise stated, resistances are in Ohms (k = 1000), and capacitances are in picofarads (pF) or microfarads (µF). 2. DC voltages are measured from point indicated to chassis ground using a Motorola DC multimeter or equivalent. Transmitter measurements should be made with a 1.2 µH choke in series with the voltage probe to prevent circuit loading. - Page 22 MAINTENANCE CH ACT Channel Activity Indicator Signal (Fast Squelch) CH KP ID Control Head Keypad ID (Data) Lines CH REQUEST Control Head Request from Control Head *P Clock Signal CNTLVLTG PA Power Control Voltage CNTR AUDIO Audio Lines of the Controller COL x Keypad Matrix Column x Chip Select Line PCIC / FRACN...
