Short Vents Long Vents
Micro Moulds use tube-shaped vents, as in traditional ear
Moulds, but the length is shorter than standard vents. There-
fore, the Micro Mould vent effect is much larger compared to
a standard vent with the same diameter. Genie prescribes the
vent size, when Micro Mould is selected.
Check the Micro Mould vent size under Acoustics in Fitting
step. For further information about selecting vent sizes and
effective vent sizes please refer to the Genie helpfiles under
Acoustics.

Canal RITE Moulds use tube-shaped vents just like Micro Moulds.
However, the vent is a little longer. Still, the canal’s vent effect
is a little larger compared to a standard vent with the same
diameter. Genie prescribes the vent size (from X Large to No
Vent) when Micro Mould is selected.
To reflect the actual diameter select the vent size for long
vents, e.g. Large (long).

Attaching the Micro Mould
When fitting Oticon Acto RITE hearing devices with Micro
Moulds follow the instructions below:
Find the correct Receiver unit length and attach it to the
instrument (see Selecting and Fitting Receiver Units).
1. Carefully insert the Receiver into the Micro Mould and
push until you hear/feel a click.
2. When inserting the Receiver into a modified Micro Mould
with a longer canal, use the Mould tool to snap the Receiver
more deeply into the Mould, as illustrated on the following
page.
3. The Mould can rotate axially to ensure maximum comfort.
Before placing the Mould in the ear, turn the Mould until
the up indicator points upwards.
