Safe posture
4 Safe posture
Before changing the operational mode of ALLUXTM using the Application Remote Control or before
adjusting or setting ALLUXTM using this App, the user needs to take a posture which is safe even if
hydraulic resistance changes. This posture is referred to as ‘safe posture’. Explain to the user about
safe posture.
[Request for safe posture]
If ALLUXTM is not in the safe posture when adjusting or setting ALLUXTM, a popup is displayed.
Make sure that the user is in a safe posture, and then tap the “OK” button to reflect the adjustments
or settings. If you tap the “Cancel” button, the adjustments or settings will be cancelled.
■Explain to the user about the safe posture, and ensure that the user
understands it.
■When the user takes the safe posture without applying the body weight
to ALLUXTM, he/she must hold a handrail or sit down.
Flexion/extension resistance may suddenly change, leading to a fall.
CAUTION
[Safe posture]
:State where ALLUXTM is stationary, straight, and vertical and may be
subject to weight loading
:State where ALLUXTM is not subject to weight bearing and the knee may
be flexed and stationary.

In order to conserve power, ALLUXTM is not always in communication mode.
In order to enable the communication mode, you need to perform the following operations.
Once ALLUXTM communication is established using this App, this state lasts until communication is
disconnected.
[Communication mode enabled]
1. For 5 minutes after ALLUXTM is slightly flexed and extended
2. For 5 minutes after you apply your body weight to ALLUXTM
3. For 5 minutes after the charger or the power OFF cap is disconnected from ALLUXTM
With the Application Remote Control, it is possible to turn OFF wireless connection when the user gets
on a plane, etc. To restore wireless connection from that state, the actions such as the one shown below
are required.
1. Disconnect the charger or the power OFF cap form ALLUXTM.
2. "Apply a load on the heel 4 times intermittently" or "Apply a load on the toe 4 times intermittently".
*You can switch to either one you like with the Application Remote Control.
*Just starting this App does not connect to ALLUXTM. Tap the Bluetooth icon on the initial startup screen
(Refer to page 10) to connect to ALLUXTM.
*Just tapping the home button etc. on the smartphone does not disconnect communication with
ALLUXTM and this App keeps working behind the screen. If you tap the icon of this App again, it starts in
the connected state.

10 Calibration
When ALLUXTM is used for the first time or re-aligned or the foot part is replaced, ALLUXTM will need
to be calibrated.
1. Tap the “Calibration” button on the “Basic setting” screen,
a popup is displayed.
2. Have the user lift his/her foot to keep ALLUXTM free from
load.
*Have the user hold a handrail in parallel bars or sit on a
chair to ensure his/her safety.
3. Tap the “OK” button on the popup.
4. The popup closes and the screen returns to the “Basic
setting” screen.
■Calibrate ALLUXTM in the correct posture.
If it is calibrated under load, the user cannot walk normally and may stumble,
possibly resulting in an injury.
■When calibrating, make sure the user is safe.
If the user stands on one foot in an unstable state they may fall.
■Calibrate with definitive components attached and fully tightened.
If alignment adjustments are made, ALLUXTM may not work properly.
■Apply the toe release point setting (see Chapter 11) after calibration.
The setting the Toe Release Point prior to calibration may make normal walking
impossible or unsafe.

12 Adjusting the Stance Flexion Yielding
Factory default setting = 20 (Standard value: 15 ~ 25)
Adjust the yielding resistance so that the user feels balanced when sitting into a chair, or walking
down stairs and slopes. Gradually increase or decrease the value according to the user’s
preference and always ensure they are standing safely prior to making adjustments. It is
recommended to adjust the resistance at a normal temperature (+20˚C/+68˚F).
1. Adjust the resistance so that the user’s weight is applied equally to both feet when the user sits
on a chair.
*If the resistance is low, increase the adjustment value.
*If the resistance is high, decrease the adjustment value.
Adjustment value (min: 0, max: 40):
A stance flexion yielding adjustment value is displayed
and entered in figures.

■When ALLUXTM is used in a low-temperature environment (0˚C/+32˚F or
less), the yielding resistance may be higher. Check the yielding resistance
before starting use in a low-temperature environment. Since ALLUXTM
cannot be easily flexed, the user may fall on stairs or slope.
WARNING
■Do not touch the linkage parts on ALLUXTM when standing up to avoid
potential pinching.
■The yielding resistance, for walking downstairs or slopes, should be adjusted
after completion of all adjustment. If the adjustments have not been made
sufficiently, the user may fall on stairs or slopes.

Since ALLUXTM cannot be easily extended, the user may stumble and then
fall when initiating swing phase.
WARNING
■Check the walking condition in a place, e.g. in parallel bars, where the user's
safety can be ensured.
■The user must walk in such a way that the knee shifts to the swing phase
after it is extended.
Since ALLUXTM cannot shift to the swing phase in flexed state for double
knee motion, the user may stumble and then fall.
