Chapter 2 Radio Power
This chapter provides a detailed circuit description of the power distribution of an ASTRO APX 5000/
APX 6000/ APX 6000XE/ SRX 2200 radio.
2.1
General
In the ASTRO APX 5000/ APX 6000/ APX 6000XE/ SRX 2200 radio, power (B+) is distributed to two
boards: the transceiver (RF) board and the VOCON board
Power for the radio is provided through a battery supplying a nominal 7.5 Vdc directly to the
transceiver. The following battery types and capacities are available:
