Installation of the ATU Assembly into the FLEX -6300
Carefully place the FLEX-6300 ATU assembly in the radio adjacent to the Filter board, aligning up the
copper ringed screw “thru” holes on the ATU board with the female mounting holes (threaded spacers)
on the metal Filter board RF shield. Note that the hole on the center right hand side of the ATU assembly
that does not have a copper ring should have the existing Phillips head screw centered in it when the ATU
assembly is properly seated. Refer to the image below of the ATU assembly being seated in the FLEX-
6300.
Once the ATU assembly is properly seated,
very loosely
install one (1) M3 x 6mm Phillips head screw using
a #2 Phillips screwdriver in the bottom right hand corner mounting hole (facing the front of the FLEX-
6300) as shown below.
Do not tighten the screw at this time
.
