Fit
The Zulu H-Mod ANR kit is optimized to deliver
clarity and quieting with comfort. Contrary to most
in-helmet passive systems, this ANR kit does not
need signicant pressure to ensure quieting.
For adjustments in tting, you should refer to the
helmet dealer who provided the certied installation
of your Zulu H-Mod ANR kit. The tting instructions
for each helmet will vary considerably.

Battery Installation
The standard Zulu H-Mod requires two
AA batteries (included). Use alkaline batteries
for best performance.
A. Open the controller battery/DIP switch door
by either pressing down on the circle icon or
by pulling open the door along the notched
edges. Insert two AA batteries with the correct
polarity positioning.
B. The LED ashes GREEN when charged batteries
are in use and the power is on.
C. When batteries begin to run low the power LED
ashes RED. If the LED ashes RED during ight
the headset will continue to operate for 5–10
more hours. Install new batteries as soon as
possible at any indication of low batteries.
Battery Types
Use two AA alkaline or lithium batteries. Lithium
batteries may provide improved battery life in
colder temperatures. We do not recommend using
rechargeable batteries or mixing battery types
and brands.
Battery Life
A set of batteries can provide up to 40 hours
of power. However, heavy Bluetooth® wireless
technology usage can signicantly reduce battery
life. Under quiet conditions Zulu H-Mod will auto
shut o approximately ve minutes after the helmet
is removed from your head.

Matching Stereo/Mono Setting to an Audio Panel
The Stereo/Mono DIP switch setting should match
the signal from your audio panel. Zulu H-Mod is
shipped in Mono (the “on” position) so you only
need to change the setting if you use a stereo panel.
STEREO should be used for a stereo panel and
MONO for a mono panel. Incorrect settings result
in communications being heard in only one ear or
weakly in both. This switch does not aect auxiliary
devices, so you can enjoy auxiliary audio in stereo
regardless of how the Stereo/Mono DIP switch is set.
Front Row Center™
Front Row Center is a built-in feature that gives you
a theater-like experience, enhancing stereo sound
reproduction so that audio seems to come from all
around you, not just from your right and left.
