5.4.8 Troubleshooting
If a connection cannot be made after several attempts, there
may be interference from other sources.
The following can be tried for successful connection using
all types of dongle:
1) Turn off all other bebionic devices that use dongles as they
work on the same frequency and will disrupt communications
if activated.
2) Move the hand closer to the dongle, avoiding any
obstacles in between to make the direct line of sight link
shorter.
3) Turn the hand off, close the be program and
remove the dongle. Then, restart be,
re-insert the dongle and turn the hand on.
5.5 Operating Modes
5.5.1 Overview
The main screen below is where the configuration of the
bebionic hands takes place. It is advised that the user
understands each of the available functions before the hand
is configured.
5.5.2 Control Strategy
The hands can be controlled by either using one or two
electrodes, this is dependent on the user’s ability to use
their muscles to produce the required signals. The number
of electrodes used has an effect on which operating modes
can be used. The following clarifies this:
Dual (Site) Electrodes
Modes 4 & 5
Single (Site) Electrode
Modes 0, 1, 2 & 3
5.5.3 Open / Close Strategy
The signals to open and close the hands can be reversed if
the user requires.
Single Site Control
Select either Electrode A or
Electrode B to control the hand.
Dual Site Control
Electrodes A, B:
Electrode A opens the hand
Electrode B closes the hand
Electrodes B, A:
Electrode B opens the hand
Electrode A closes the hand
Once the hand has been read successfully, the bebionic
main form will change to highlight its current configuration.
To read the current hand configuration, click the ‘
Read from
Hand
’ button and a progress form should appear, indicating
the status of the communications. This will only take a
few seconds, and the form will automatically close if it is
successful.
5.4.7 Hand Configuration
When the hand has been successfully connected, the
buttons ‘Send to Hand’ and ‘Read from Hand’ will be
enabled to allow the hand configuration to be read.
