Talking in Noise (Push-to-talk/PTT)

STOP: Until you have passed your Earpiece Fit Test you should

not use the communication functions in noise.

The center POWER button is used to turn the device on and to communicate. The push-to-talk works like a

walkie-talkie would - you must push the button each time for the duration you need to talk, and release to

hear anyone else who is also using a device. When pressed, the amulet will light up and you will hear a short

ascending “bi-dip” audio prompt: this means you are connected and that other team members can hear you.

You don’t need to shout or raise your voice. Everyone wearing the amulet on your radio band will hear you.

When you release, a short descending “bi-dip” can be heard: only you can hear this and is designed to let you

know your message has been sent.

If you hear a very short negative “beep” audio prompt: you and another user are trying to communicate at the

same time. Wait and try again.

NOTE: if you have a poor t, all team communication will be aected. Speak normally: speaking very quietly

will also aect sound quality.

TIP: You can use other communication devices (such as radio or mobile phone) without removing your SonX –

as long as you don’t touch the device to the SonX earpiece. Touching the sensitive membrane on the outside

of the earpiece could trigger the device to engage impulse clipping and temporarily block sound completely.
