POST-INSTALLATION ADJUSTMENTS
After installation, the A711L may require adjustment of some functions to compensate for airframe
and equipment specific issues, and to suit user tastes. Locations of these adjustments are as shown
in section 2.14. All are 20-turn miniature trimpots, except as noted. “MUSIC” input may be for any
entertainment audio feed, such as CD, tuner, etc.
Note, back adjustments (alerting) are NOT normally field adjusted, unless required. The 37
Pin connector (not required for this test) above these adjustments may be removed to
facilitate the adjustment of these alerting pots. Be extremely careful of any adjustments to
these settings, as incorrect levels will be highly problematic in the airframe. These are
normally bench adjustments.
