4.3.3 Audio
Audio levels for the PS Series have already been set and should not need to be
changed. Deviation can be checked by pressing the FUNCTION key until the
appropriate LCD screen is reached (see Figure 4-6).
Figure 4-6.
When the LCD display is in DEVIATION mode, the maximum deviation should
occasionally reach 100% (indicated by the thick bar). If the 100% level is never
reached or exceeds 100%, the level needs to be adjusted.
The output level from the audio source should be adjusted to give a peak
deviation of 75 kHZ (as described above).
If the correct deviation cannot be obtained, the audio gain can be raised or
lowered by pressing the FUNCTION key until the appropriate LCD screen is
reached (see Figure 4-7).
Figure 4-7. Audio Gain can be adjusted through the LCD display
When the AUDIO GAIN screen appears, the value may be raised by pressing the
RAISE key or lowered by pressing the LOWER key until the desired deviation is
reached. The Deviation Screen is displayed through the FUNCTION key.
