Test Frequencies for Display and Non-Display Radios

The radio channels and test frequencies are listed in Table 4-4. The channels are selected using the
channel selector switch located on top of the radio, as shown in Figure 4-1 on page 4-3. The test
environment and channel spacing for any particular frequency is selected using 'side buttons 1 and 2',
as listed in Table 4-1 on page 4-4 and Table 4-2 on page 4-5. The display radio shows the selected
parameters on the radio display, and sounds the corresponding number of beeps and tones listed in
Table 4-1and Table 4-1. The non-display radio only sounds the beeps and tones.
Note: On UHF LTR models, radios must be in conventional or LTR modes.
