BEFORE USING IndiGo
IndiGo has the same safe working load as the bed to which it is fitted.
1. Identify that the bed is equipped with IndiGo by locating the IndiGo emergency stop switch,
the IndiGo cover and/or the IndiGo wheel.
2. Prepare for patient transport according to bed IFU and all applicable safety information
and operating instructions.
USING IndiGo
IndiGo Activation / Deactivation and Brakes
Activate / deactivate IndiGo and brake using the pedals located on each corner of the bed. Operate
the pedals with your feet while wearing suitable shoes. Do not operate the pedals with your hands.
The pedals have three positions as shown in Fig. 2:
IndiGo ACTIVATED: a centered drive wheel
engages the Àoor when IndiGo is activated.
FREE: all four casters are free to rotate and
swivel and IndiGo wheel is lifted off the Àoor.
BRAKE: brakes are applied on all four casters
and IndiGo wheel is lifted off the Àoor.
When activating IndiGo, place the pedal in the
most upright position. The IndiGo wheel will be
lowered to the Àoor and blue lights illuminate to
signify IndiGo is active.
See Fig. 3:
Refer to Light Indications (shown on page 12) to determine when IndiGo is ready
to use.

EMERGENCY STOP SWITCH
The IndiGo Intuitive Drive Assist comes equipped with Emergency Stop Switches located at both the foot
and head ends of the bed.
The emergency stop switch provides a gradual, slow stop rather than an immediate
hard stop.
When the emergency stop switch is activated, an electric brake is applied to reduce momentum and slow
the bed down until stopped. At the same time the blue lights will turn off, and the drive wheel will raise up
from the Àoor.
Emergency Stop Switch Locations
Activate Emergency Stop Switch
ವ When the emergency stop switch is pushed down, the electric brakes
are applied to reduce momentum and slow the bed until stopped.
ವ The blue lights turn off and the drive wheel retracts up
under the bed and off the Àoor.
Once the switch is pushed down, it will stay down, with IndiGo deactivated,
until the emergency stop switch is reset and the brake pedal is cycled to the
free position then back to the activated position.

Maneuverability
IndiGo replaces the bed's ordinary steer lock function with a drive wheel centered under the bed, which
improves the maneuverability and control. The drive wheel effectively minimizes the space needed when
taking corners or full 360° turns. See Fig. 12 and 13
In most cases, it is bene¿cial to keep IndiGo
activated in con¿ned spaces and crowded areas.
Ensure there is space to operate before forward
or reverse movement.
Note that deactivating IndiGo
(pedal in free position), allows for
small positioning adjustments and
sideways movement. See Fig. 14
Drive Assistance
To use IndiGo:
ವ Activate IndiGo (1) using the
pedals on any corner of the bed.
ವ Move bed slightly away from
wall to access to the bed's
power cord (2). See Fig. 15.
ವ Unplug power cord from
the wall.
ವ Push or pull bed gently to begin drive assisted movement.

To fully bene¿t from IndiGo:
ವ Keep a constant pressure while moving on Àat surfaces and up slopes.
ವ Pull gently to decelerate and lean backwards to stop (brake assistance). See Fig. 16
ವ Control speed by a light constant pull
while moving down slopes (brake
assistance). IndiGo will provide brake
assistance. See Fig. 16.
ವ IndiGo may be kept activated in and
out of elevators. Note that temporary
deactivation allows for small positioning
adjustments and sideways movement
if required.
IndiGo reacts to force applied by the user. IndiGo gives progressive assistance
up to a maximum speed of 5km/h (3mph).
Sleep Mode
When IndiGo is activated and the bed is not moved for approximately ¿ve minutes, IndiGo goes into sleep
mode. The wheel lifts off the Àoor and the blue lights turn off.
To re-engage IndiGo, move the brake pedal to the free position and then back up to the activated position.
The drive wheel lowers to the Àoor and the blue lights turn on, indicating IndiGo is now active.
