DO NOT use your CENS® ProFlex earpieces without either the
electronic or passive module being fitted.
Once the devices are switched on, you will be able to hear sound
as normal; however, when a loud sound is detected the device
will automatically reduce the volume to a safe and comfortable
level. After the loud sound has passed the volume is automatically
returned to normal.
(Please note: There may be a up to 5 second delay followed by an
activation melody after the devices are switched on before the
amplified sound is heard.)
