Thumb contact point:
The adjustment option makes it possible to
optimise the contact point of the thumb with
the opposite index and middle fingers (for the
tripod grip), or with the index finger only (pinch
and precision grips). The adjustment screw is
located below the CMC joint of the thumb.
Perform the following steps to make the adjust­
ments:
1) Turn off the energy supply to the terminal
device (e.g. button in the charging recept­
acle on the prosthetic socket or switch on
the elbow joint).
2) Separate the terminal device from the pros­
thetic socket.
3) Raise the gaiter on the wrist joint and
expose the adjustment screw.
4) Use a 1.5 mm Allen key for the adjustment
screw of the thumb contact point on the
MCP joint of the thumb.
5) Turning the Allen key clockwise moves the
thumb towards the palm (reducing the dis­
tance).
Turning the Allen key counterclockwise
moves the thumb away from the palm
(increasing the distance).
INFORMATION: The effect of the rota­
tion movement applies for both the
right and left bebionic hands.
The movement of the thumb cannot be
observed while the adjustment is being
made. An adjustment of one turn is suffi­
cient.
6) Mount the terminal device on the prosthetic
socket and, with the energy supply turned
on, check the contact point by closing the
terminal device. If the adjustment of the
contact point was not sufficient, open the
hand fully and perform the adjustment
steps again.
