PROGRAMMING SOFT LIIMITS
1
Enter Soft Limit Mode: While holding the “Return” key, press and hold the “Preset 1” key for 6 seconds. Two short
beeps followed by one long beep indicate that you have entered Soft Limit Mode. While in Soft Limit Mode, the chair
will be able to move through its full mechanical range of travel.
2
Position the chair: Press a directional key (up, down, recline, incline) to position the chair at its desired soft limit
position.
3
Set soft limits: While pressing and holding the “Return” key, press the directional key (up, down, recline, incline)
for the direction that you want to limit. Two long audible beeps will indicate successful programming of that soft
limit. Example: To set the lower limit of chair height, press and hold the Return key and the Chair Down arrow
key.
Soft Limits are the software controlled position limits for the hydraulic chair movements. These can be programmed
using the foot switch or any touchpad that controls chair movement. Soft limits are factory set and should only be
adjusted by a technician.
4
Exit Soft Limit Mode: while holding the “Return” key, press and hold the “Preset 1” key for 6 seconds. Three
audible beeps indicate that you have left Soft Limit Mode. Once exited, the chair will operate within the
movement constraints that have been programmed.
If, while in Soft Limit Mode, no keys are pressed for over 60 seconds, the chair will automatically exit Soft Limit Mode,
at which time three audible beeps will sound. Once exited, the chair will operate within the movement constraints
that have been programmed.
