Peak Performance Tips
• Start with an excellent fit—see “Fitting your
headset,” on page 4.
• Set the Zulu 3 Stereo/Mono DIP switch to match
the signal from your audio panel (see “Matching
Stereo/Mono Setting to an Audio Panel” on page 8).
• Keep cell phones at least 12 inches from the
Zulu 3 controller and headset when making calls
to reduce static noise during phone calls.
• To conserve battery life, turn off Bluetooth mode
when not in use.
• You can use auxiliary devices such as a music
player by connecting to the Zulu 3 auxiliary
input jack and a cell phone by connecting via
Bluetooth wireless technology, or through the
3.5mm audio device/iPhone cable provided.
• To ensure peak ANR performance and comfort,
replace the ear seals, head pads, and mic muffs
every 18 months. These are wear items that are
not covered by the Lightspeed warranty and
are available for purchase on our website at
LightspeedAviation.com/Accessories.
• We encourage you to register your headset at our
website, LightspeedAviation.com. In the event
your headset may require service, registration
helps assure quick and efficient processing (see
“Where is my product serial number” on page 17).
• When packing your headset
into its case, close the
sliders and place the mic
over the headband to
avoid chafing the boom.
