4.1 Control End
The stretcher has height-control push buttons and a manual over-
ride handle for non-powered operation.
NOTE: The stretcher is ready for use whenever the battery is charged,
and automatically goes into Sleep Mode when not in use to preserve
the battery. Pressing either up and down button will bring the
stretcher out of sleep mode.
STRETCHER HEIGHT-CONTROL / LEG-CONTROL
Stretcher height-control / leg-control buttons are located on the
foot-end of the stretcher (Figure 1).
The arrow above the horizontal line on the button denotes the
movement of the trolley (up or down) when out of the vehicle and
the button is pressed.
The arrow below the horizontal line on the button denotes the
movement of legs (raise or lower) when loaded onto into the
loading arm, prior to loading/unloading in and out of the vehicle.
EXTEND: Extends the legs (raise the stretcher when on the
ground / lower the legs when stretcher is on the loading arm)
RETRACT: Retracts the legs (lower the stretcher when on the
ground / raise the legs when the stretcher is on the loading arm)
The buttons can also be used to set the load height of the stretcher.
Hold both height-control buttons (A) together for 5 seconds to
set the automatic loading height stop position for a designated
ambulance. See "Set the Loading Height" on page 34.
RELEASE BUTTON (B)
This button unlocks the stretcher from VIPER Loading System.
This function operates only when unloading the stretcher from
ambulance.
MANUAL OVERRIDE RELEASE HANDLE (C)
This handle overrides the stretcher's powered actuator system
allowing operators to be able to raise or lower the stretcher
manually and load/unload the stretcher into/out of the vehicle if
for whatever reason the stretcher battery is depleted and unable
to recharge the battery. To use the manual override system, see
"Manual Override" section on page 26. Use additional trained
helpers as needed. See "Using Additional Help" on page 7.
