Performance Checks: Display Radio Test Mode (Dual-Display Version) Sec 1: 5-5
5.2.2 RF Test Mode
When the ASTRO APX 7000 radio is operating in its normal environment, the radio's microcomputer
controls the RF channel selection, transmitter key-up, and receiver muting, according to the
customer codeplug configuration. However, when the unit is on the bench for testing, alignment, or
repair, it must be removed from its normal environment using a special routine, called RF TEST
MODE.
While in RF test mode:
• Each additional press of Side Button 2 advances to the next test channel. (Refer to Table 5-3.)
•Pressing Side Button 1 scrolls through and accesses the test environments shown in
Table 5-4.
NOTE: Transmit into a load when keying a radio under test.
