Safety Devices:
Footrest obstruction sensor
swivel seat cut-off switch
Final limits
Warranty: Five years on drive train (motor and gear)
Two years on all component parts
Notes:
• The call/send controls (transmitters) use infrared signals.
There are two infrared sensors located on the chassis
access cover. There is a combination of 4 different fre-
quencies the transmitters can be set to (both transmitters
must be set to the same frequency).
• There is a half second delay after a control button is
pressed before the lift starts to move. After the lift stops,
the up/down controls are disabled for 3 seconds.

Caution!
The control board is sensitive to static charge. To avoid
damage, touch a metal surface on the lift to discharge
yourself of static charge. never touch the chips on the
control board.
Always disconnect the 115 VAC power when working
on the lift.
Remote Control (Transmitter) Frequencies
The standard wireless remote controls (transmitters) use
infrared signals. one button on the transmitter is up and
other button is doWn. There are two infrared sensors
(receivers) located on the chassis access cover.
a combination of 4 different transmitter frequencies allow
for more than one lift in a single home. The two transmit-
ters must be set to the same frequency (for each lift). For
example 1 to 1, 2 to 2, etc.
To change a frequency:
ensure the infrared receivers (in chassis cover) are con-
nected to the control board. use the seat control to move
the lift away from the end of the track. Take the back off of
J1 control Board

the transmitters and set the red jumpers (in each transmit-
ter) to the same code. change the corresponding code in
the control board J1 (see chart). press and hold the yellow
"learn" button on the control board, then press and hold
one of the up/down buttons on one of the transmitters. The
controller board should beep and the lift start to move after
you release the transmitter button when the frequency has
been successfully changed.
note that if the lift is on an upper or lower limit switch, the
frequency may not be able to be changed.
To access the controller board the footrest support and
shroud must be removed. The footrest plug can be tempo-
rarily jumpered out while changing frequencies.

When the lift is commanded to run, the controller board
will immediately sound a single beep and the lift will pause
momentarily before moving.
If the lift is commanded to stop by releasing a control
switch/button, the lift will decelerate to a stop in 1.5 seconds.
however, if the switch/button is pressed again, before the
lift has reached a complete stop, the lift will immediately
start to accelerate.
The lift has a fixed acceleration rate of 3.0 seconds.
The priority of the input signal to the lift for a direction com-
mand is dependant on which input was received first.
