TROUBLESHOOTING
NOTHING WORKS — NO POWER
1. Verify the outlet is supplying power.
2. Ensure the power cord is not pinched,
frayed, or damaged in any way. Replace the
Power Cord if damaged.
3. Ensure all power cord, T-Cable, Hand
Control Pendant, and Control Box
receptacles and plugs are seated and fully
inserted.
4. Ensure the Staff Control does not have
functions locked out.
5. Plug the Hand Control Pendant directly into
the Control Box. If the bed works, replace
the T-Cable.
6. Replace the Hand Control Pendant with a
known good operating Pendant. If the bed
works, replace the Hand Control Pendant.
7. If the bed still isn’t functional after steps 1-6,
replace the Control Box.
8. New Control Box installation will require
motor Initialization.
NOTE: Service Control Box Motor
Initialization Procedure as well as detailed
troubleshooting and service instruction can

AUDIBLE SYSTEM WARNING (INTERMITTENT BEEP)
NOTE: A function that is faulty or has lost
motor position will cause the Control Box
to beep intermittently when the faulty
function’s Hand Control Pendant button is
depressed. All buttons depressed after the
error function will also be non-functional
and will cause a Control Box beep. If
equipped with a Staff Control, the staff icons
will also ash to indicate a system error.
When the Audible Beeping Error signal is
heard:
1.
On the Hand Control Pendant, simultaneously
press and hold both the HI/LO UP and
HI/LO DOWN buttons (the Control Box
should start beeping) for approximately ve
seconds until beeping stops.
2. Reinitialize the motors by lowering the bed
completely. In the following order, press
the Hand Control Pendant buttons until the
motors stop:
a. HI/LO DOWN
b. HEAD DECK ANGLE DOWN
c.
KNEE AND FOOT DECK ANGLE DOWN
3. This lowering of the motors will reset
the system and should resolve minor
synchronization or position lost issues.
Check the bed functionality.
4. If an audible error beep occurs during reset
lowering of a function or while checking
functionality, the function that initiated the
beep is faulty.
5. After the faulty function initiates the beep,
all other button functions will cause a beep
and become non-functional.
6. To operate and use the other good
functions, perform step 1 again to reset the
system.
7. Reinitialize the motors as in Step 2 but only
lower the motors that did not initiate the
audible error beep.
8. These functions will operate normally until
the faulty function button is pressed again.
