4-4 Performance Checks: Radio Test Mode
NOTE: Once your radio is in a particular test mode, you must turn off the radio and turn it back on
again to access the other test mode.
4.2.2 RF Test Mode
When the SSE 5000 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 press of the one-dot side button advances to the next test channel. (Refer to Table 4-3 .)
• Each press of the two-dot side button scrolls through and accesses the test environments
shown in Table 4-4 .
