The gooseneck should be fitted to the whip antenna stud
and the whip
unfolded to it maximum height. When ever a channel is changed, and
the
next time the 940 is switched to transmit the antenna tuner will
tune
automatically. If using the 940 while
walking in the backpack
configuration it is suggested that while in receive standby
mode the
collapsible antenna be only extended to half height and secured
using
the velcro tab. When a call is received extend
the antenna to full
height before transmission.
