AINA Smart Button

PTT button

A Bluetooth button can be used to control the GroupTalk PTT function on the phone while the phone is still in the pocket.

Typically, the Bluetooth button is used in combination with the standard wired head-set that comes with the phone or with a more professional air-tube head-set.

The benefit of the Bluetooth button is ease of use and the fact that it has a battery that lasts for a year and does not require charging every night.

The AINA Smart Button offers PTT, queue and panic alarm buttons on a user friendly device.
