This is Flex PC running over audiometry software. Hold Left, Center or Right on the bar, or use your hotkeys, and the monitors in the booth reward. Change the stimulus, volume and lights, or tap the gear to set your own hotkeys.
Left, center and right
Click the big buttons or use your hotkeys. Hold to reinforce for as long as you press, or use timed activation.
The whole remote
Choose Video, Toy, Lights Only or Custom, change the volume, mute, start Distract and switch the lights.
Always ready
Hotkeys keep working while your audiometry software is in front. Pause them with one click, and fade the bar with the slider.
Camera View
With the optional Flex Cam, see the booth on your screen and record a session with one click.
Hands on the keyboard, eyes on the patient.
No remote to reach for between presentations, so reinforcement lands the moment the child turns. Setting up takes a few minutes.
