Association Procedure
The wireless controllers will only function with the chair they have been “associated” with.
This prevents unwanted movement in locations with more than one chair.
Each wireless controller’s association is preset at the factory. This procedure is only required in
the event of a malfunction, if a new controller is purchased*, or if you are attempting to use the
controller with a chair other than the one it was originally associated with.
* NOTE: The chair’s PC board only stores the last two associated controllers. To ensure proper
operation, Midmark recommends reassociating both controllers (hand & foot) if a new
controller is purchased.)
Association Procedure:
A. Using the wired hand or foot control, press & hold
the Stop & Home buttons simultaneously.
(after two seconds you will hear a single “beep”)
B*. Using the wireless hand control, press & hold
the Stop & Home buttons until you hear three “beeps”.
(One long “beep” indicates the association failed. Unplug unit for
one minute and repeat Steps A & B.)
C. Check for proper operation of wireless hand control.
D. Repeat procedure for wireless foot control.
* Note: Step B must be performed within 3 seconds of Step A.
