9.12 Calibrating the Paddles
kNOWiNG WhEN CaLibRaTiON iS NEEDED
The paddles are pressure-sensitive. When properly calibrated,
the paddles allow the operator to control the speed of the belts.
Applying less pressure should make the belts move slowly, while
depressing the paddle fully should make the belts move as quickly
as possible.
Recalibration of the paddles is needed when you observe any of
the following:
●
there is no difference between a light touch of the paddle and
fully-depressing the switch (the belts should not immediately
begin moving at full speed with only light pressure)
●
if the belts continues to move when the switch has been
released (no pressure)
CaLibRaTiNG ThE PaDDLES
1. If needed, disconnect the interconnect cord. Press the power
switch
. Wait until the lights on the control panel turn off
and the control panel is inactive (about five seconds).
Note:
The calibration procedure cannot begin unless the
interconnect cord is disconnected, the power is OFF, and the
control panel is inactive.
2.
Do not
touch the up/down paddles.
3. Simultaneously press the brake
and mode
buttons
on the control panel (Figure 66).
Note:
If Step 3 is completed properly, the control panel will
illuminate with a red background. The software version is briefly
shown, then the calibration sequence begins. If the background is
not red and the standard screen is displayed, repeat Steps 1-3.
4. Instruction: “Throttle UP 100% Then Press a Key”: Press
and hold the ASCEND part of the paddle fully, then press the
mode or brake button.
5. Instruction: “Throttle DW 100% Then Press a Key”: Press
and hold the DESCEND part of the paddle fully, then press
the mode or brake button.
6. Instruction: “Throttle IDLE 0% Then Press a Key”: Leave
the paddle in the neutral position and press the mode or brake
button.
7. If you completed all steps properly, the display will show
“Calibration OK!” Begin using the chair normally.
iF ThE CaLibRaTiON FaiLS
Repeat Steps 1-7. Do not press the paddles until directed to, and
press in the proper direction. If the paddles cannot be recalibrated,
contact Ferno Technical Support for assistance (page 2).

Paddle Calibration
The paddles cannot be re-calibrated when the
interconnect cord is connected. Disconnect
the interconnect cord and install fresh “AA”
batteries in the control panel if needed.
