At the back of this booklet your hearing care profes-
sional can indicate the type of vent used in your hear-
ing aid, if any.
Right/left identification
If you are wearing hearing aids
in both ears, it is easy to tell
them apart. Most models will be
marked with a red Widex logo for
the right ear and a blue logo for
the left ear. The arrow shows the
position of the logo. An alterna-
tive model has a red or a blue
shell, respectively.
