functions are:
• Switching between 1st
and 2nd Mode
• Enable and disable
Standing Mode
• Change swing phase
dynamics
Communication
between the C-Leg and
the remote must be
established before any
of the functions can be
activated. Communication
is established by holding
down the '3' key until
the C-Leg vibrates.
Communication between the C-Leg and remote will
end after a short period of time in order to save
battery power.
Switching between 1st and 2nd Mode
After communication has been established, hold down
the '2' button until the C-Leg beeps twice to signal that
the knee is in 2nd Mode. To change back to 1st Mode,
communication must be established by holding down
the '3' button and then the '1' button is held down
until the knee beeps once to signify that the knee is
in 1st Mode. NOTE: It isn't possible to switch into 3rd
Mode with the remote control. Third Mode must be
activated manually by bouncing on the heel.
Enable and disable Standing Mode
Standing Mode allows the C-Leg user to lock the knee
against flexion at an angle between 7 and 70 degrees of
knee flexion.
Standing Mode must be enabled using the remote
before the user can utilize this feature. Once Standing
Mode has been enabled in the C-Leg it will stay enabled
until it is disabled via the remote. After establishing
communication with the C-Leg by holding down the
'3' button, Standing Mode is enabled by holding down
the '1' and '2' buttons until the C-Leg beeps three times
and is disabled by holding down the '1' and '2' buttons
until the C-Leg beeps one time. In addition, the knee
must be in full flexion in order to enable or disable
Standing Mode.
Once Standing Mode has been enabled through the
remote, the C-Leg user will activate this function in the
following manner:
Flex and hold the knee for 1 second. The knee must be
flexed between 7 and 70 degrees and it is best to flex the
knee just past the desired 'locked' angle. After holding
the knee for 1 second, slightly extend the knee to the
desired angle of knee flexion and hold the knee for 0.8
seconds. The C-Leg will vibrate and the flexion valve will
close to block flexion of the knee.
To deactivate Standing Mode, the C-Leg user can either
extend the knee quickly or extend the knee within 7

degrees of full extension.
Change swing phase dynamics
The final remote function is the ability to change the
swing phase dynamics. The remote allows the C-Leg user
to make changes to the swing flexion resistances set by
the prosthetist. There are three possible settings that the
remote can toggle through:
• Standard - This is the swing flexion setting
programmed by the prosthetist.
• Comfort - This lowers the dynamic factor by one
and increases the knee angle threshold by 5 from the
Standard setting.
• Dynamic - This increases the dynamic factor by one
and lowers the knee angle threshold by 5 from the
standard setting.
The C-Leg user can toggle between these three settings
using the remote. After activating communication with
the C-Leg, holding down a combination of the '1' and
'3' buttons will go to a lower swing phase adjustment
and holding down a combination of the '2' and '3'
buttons will go to a higher swing phase adjustment.
The following beeps will sound when the changes have
been made:
• Comfort (lowest) - 1 beep
• Standard (medium) - 2 beeps
• Dynamic (high) - 3 beeps
