Certain SL30, SL40 and GNS 480 units may generate spurious emissions when transmitting. When they exist with a particular unit, it is unlikely that the pilot will be aware of the condition. Nevertheless, affected units are to be returned to Garmin for calibration that provides a permanent correction for this condition.
We issue a Flight Design Service Bulletin. Please note that SB lists the incorrect allen wrench size for removing the radio. The SB states 2.5mm, but it’s actually 3/32”
