improper workon two-w ayradios
The elect romagnetic radiation from two-w ay
ra dios can inter fere with the on-board elec‐
tronics if RF transmitte rsare manipulated or

WARNING Risk of accident from incor‐
re ct ope ration of two-w ayradios
If yo u operate two-wa yra dios incor rectly in

could inter fere with the on-board electronics,
e.g.:
Rif th e two-w ayradio is not connec tedto
an exterior antenna
Rif th eex terior antenna is not cor rectly
mounted or is not of low reflection
This could jeopardies the operating saf etyof
