G.10 RF interference
Interference induced from nearby RF transmitters might cause system failures
and in extreme cases permanent damage to the Fleet77/55 equipment. If
problems with interference from HF transmitters are encountered
advisable to mount ferrite clamps on the coax cable in order to provide
suppression of induced RF. The ferrites will have no effect on the differential-
mode signals but increases the impedance in relation to common-mode RFI.
G.10.1 Recommendations
1-5 pcs. hinged clamp cores (e.g. the RFC or SFC series from Kitagawa)
mounted on the antenna cable nearby the ADU.

Typically this will result in the handset error message: "ACU comm. error".
