5.2.2 RF Test Mode
When the ASTRO APX 7000XE 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 via 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
on page
after the button press (for example, five tones indicates channel 5).
• Pressing Side Button 1 scrolls through and accesses test environments shown in
page 2:5-3. The test environment is represented by the number of tones emitted by the radio
after the button press (for example, 11 tones indicate AST).
NOTE: Transmit into a load when keying a radio under test.
