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.

Fig. 2

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:

Fig. 3 Refer to Light Indications (shown on page 12) to determine when IndiGo is ready to use.
