Helmet Mount
Align the speaker hole in the mount with the hole in
the helmet. You may need to enlarge the hole in
the helmet to allow sound to pass.
Use the tie wraps to attach the mount to the
helmet, keeping the speaker hole in the mount
aligned with the open space in the helmet.
Your N3’s speaker hole must be aligned with the
speaker hole in the mount. Failure to do so may
result in inaudible alarms. Ensure that the pressure
sensor and speaker holes on the back of N3 are not
obstructed by items such as adhesive Velcro™.
Slide the N3 into the mount.
The mount fits in a recess as shown.
Using the
Flip LCD
function on the
Display Opt
menu,
your N3 can be oriented with the buttons in either
direction, on either side of your helmet.
From the main menu, use the top and bottom
buttons to scroll to
Display Opt
. Press the middle
button to select
Display Opt
, then use the top and
bottom buttons to scroll to
Flip
. Press the middle
button and the screen will flip upside down.
