HOW TO TURN ON/OFF
AND ADJUSTING VOLUME (cont'd):
3. Volume control is located on the side of the device, see
diagram below. To adjust sound volume, hold the device
between your left hand thumb and index/middle fingers as
illustrated in the diagram on the earlier page, turn the knob
with the thumb of your left hand to regulate volume up or
down. Slowly turn the knob to your left to reduce sound
volume, vice versa to increase.
For best results, we suggest start using the device with
volume on low, gradually increase it per your preference.
To regulate sound volume while wearing, you will have to
remove the device from your ear and replace it when done.
Do not set the volume too high. High volume may cause
excessive feedback and pose health risk.
Do not apply much force to hold the Welko™ InfiniEar® ITE
Rechargeable Hearing Amplifier while turning ON/OFF the
device or adjsuting its volume, it may abruptly fall out of
your hand if not in control.
