Adjusting the AFT
The adjustable Frequency Tuning (AFT) knob is located directly behind the volume
control. The AFT dial operates independently from the volume control and enables
the user to adjust the sound frequencies to his/her individual levels.
1. Place the Walker's Power Muff
QUADS™ on your head, with red
volume control on right ear and
the blue volume control on left
ear, adjust the padded
headband to create a
comfortable fit.
2. Turn on the power to your Power
Muff QUADS™ and adjust the
volume to a comfortable level.
3. To increase the higher frequency
sounds in your right ear, rotate
the AFT control forward (toward
your nose).
4. To increase the higher frequency
sounds in your left ear, rotate
the AFT control backward
(toward the back of your head).
That's it! A custom adjustment
any time, every time. No matter
where you are or how you are
using your Power Muff QUADS™,
with the improved AFT control,
you're sure to have the custom
sound that meets your needs.
