BEFORE USING IndiGo
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:

CARE AND PREVENTIVE MAINTENANCE
Actions To Be Completed By Caregiver Daily Weekly
Check that the IndiGo cover is undamaged ¥
Check that IndiGo is activated when pedal is in its most upward position ¥
Check the emergency stop assemblies for signs of damage ¥
Check that applicable IndiGo labeling is present and legible ¥
If the result of any of these tests is unsatisfactory, do not use IndiGo. Contact Arjo
or an Arjo-approved service agent.
General
• Examine the IndiGo for obvious signs of damage.
• Exercise the unit’s operation, including the emergency stop switches. If any abnormalities
are observed, refer to the Troubleshooting chapter.
• Examine the IndiGo cables for cuts, abrasions, kinks or other deterioration. Contact Arjo
if damage is observed. Refer to Contact information in the back of this manual.
• Examine the IndiGo drive wheel and tire assembly for damage. If abnormalities are observed,
replace the Drive Wheel Assembly. Refer to Drive Wheel Replacement procedures in the Servicing
chapter to replace.
• Visually inspect the gas spring for excessive oil on shaft. Ensure the gas spring maintains downward
force on the drive wheel when IndiGo is engaged. If excessive oil is present on the shaft or the gas
spring does not maintain downward force when IndiGo is engaged, replace the gas spring. Refer to
Gas Spring Replacement procedure in the Service Manual.
• Check all accessible nuts, bolts and other fasteners to ensure they are present and correctly
tightened.
• Check that IndiGo does not interfere with the scale function through the bed’s full range of motion.

FCC COMPLIANCE STATEMENT:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1)This device may not cause harmful interference, and
(2)This device must accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy, and if it is not installed and used in accordance with the
instruction manual, it may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which case
the user will be required to correct the interference at his own expense.
REQUIREMENTS FOR CANADA:
This device complies with Industry Canada license exempt RSS standard(s). Operation is subject to
the following two conditions: (1) this device may not cause interference, and (2) this device must accept
any interference, including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire
de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si
le brouillage est susceptible d'en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type
and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential
radio interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec
une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada.
Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut
choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.)
ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.

ELECTRICAL MAGNETIC COMPATIBILITY INFORMATION
Product has been tested for compliance with current regulatory standards regarding its capacity to block
EMI (electromagnetic interference) from external sources.
Some procedures can help reduce electromagnetic interferences:
• Ensure that other devices in patient-monitoring and/or life-support areas comply to accepted
emissions standards.
