When batteries run low, the power LED flashes red. If the power LED flashes red when you first turn on the headset, Lightspeed recommends that you install fresh batteries before take-off.

Matching Zulu’s Stereo/Mono setting to your audio panel signal For best results, Zulu’s Stereo/Mono DIP switch setting should match the signal from your audio panel. If you are using a stereo audio panel, Zulu should be set to Stereo for the best sound quality.
Some cell phones use proprietary connectors and require an adapter or special cable- call Lightspeed if you need help with your set up. To adjust the volume on a device connected to Zulu’s auxiliary input jack, use the controls on the device itself.
USING A BLUETOOTH DEVICE Note: Different manufacturers use different interfaces and names for the functions described here. See your Bluetooth device documentation for details as needed. Turning Bluetooth mode on and off To turn on Bluetooth mode: With Zulu turned on, press and hold Zulu’s Bluetooth button until you hear a long, high-pitched tone and then Bluetooth indicator LED flashes three quick blue pulses.
3. With Zulu in pairing mode, follow the menu prompts on your Bluetooth phone or device to direct it to look for Bluetooth devices. Note: Zulu’s pairing mode lasts two minutes. If this step takes you longer and the Bluetooth LED is not longer flashing alternating red and blue, start over from Step 1. 4.
ADDITIONAL INFORMATION Setting DIP switches Zulu DIP switches are factory-set to match most audio panels. You may need to adjust the Stereo/Mono DIP switch to match your setup, but in most cases, you can leave the switches set to their factory defaults. See the table on the next page for recommendations on DIP switch settings.

Frequently Asked Questions Why do I hear radio communications in only one ear? You probably have Zulu’s Mono/Stereo DIP switch set to Stereo while your audio panel is transmitting a mono signal. A stereo configuration requires two channels, one for each ear. Audio panels that transmit mono signals send audio through only one channel, so you hear audio in only one ear.
