Recalibration
•
For T688 Treatment Chair
If there is a loss of feedback from any of the actuators, a ‘position lost’ beep will be heard from the
control box when any button is pressed.
Recalibrate T688 Series
Chair using the nurse’s hand control as follows:
➢
Stage 1
– Clear System Faults
Press
both of the Up and Down arrow buttons
of the chair height function
simultaneously.
If successful a constant beeping will be heard. Hold until the beeping stops
(approximately five seconds).
Note. Both buttons must be activated at
exactly the same time
. If beeping does not start,
repeat until successful.
➢
Stage 2
– Initialise the System (Process 1)
Press
both of the Up and Down arrow buttons
for the Backrest function simultaneously and
hold
until all the actuators have stopped moving. This will drive the Backrest actuator into the
fully retracted (down), the Leg rest actuator into the fully retracted (down) position and the
Height actuator into the fully retracted (down) position. When completed the system will beep
two times to confirm.
Note
. If the system does not beep twice when all of the actuators have stopped, please contact
Fresenius Medical Care or your local representative for further assistance.
If the chair does not respond to
Process 1
, please follow the instructions below
(Process 2)
