DEVICE DESCRIPTON
The REAL Immersive System consists of a clinician tablet, head-mounted display (HMD) component, small sensors, large sensor,
sensor charger, router, router battery, HMD controller, power cords, USB cables. Note: Bands sold separately.
Tablet is fitted with a touch screen, a power/lock key that turns the component on or off, and a charger/accessory port.
Head-mounted display (HMD) provides visual feedback of virtual reality applications in concert with the REAL Immersive System
tablet and small and large sensors.
Small and large sensors are equipped with mechanical and electrical components that measure motion and direction in physical
space and then translate that information into a virtual environment.
The sensor charger powers the sensors.
HMD controller (Only to be used in certain troubleshooting and administrative tasks. Not used during patient therapy.)
In the event of EM disturbances, REAL Immersive System may not operate accordingly to what is described in device
description.
The REAL Immersive System is a Type B Applied Part.
The following are frequently used functions:
HMD
• Plug HMD power cord into wall outlet and HMD to charge device.
• Press power button to power on HMD or restart HMD. The power button is on top of the HMD.
HMD Controller
• Buttons on the controller are used to either power on, connect to HMD, access settings, or control volume.

There are no preventive inspection, calibration, and maintenance necessary for the REAL Immersive System besides the
initial set up procedure. During the one-year product lifespan of the REAL Immersive System, the device will continue to
perform safely without any routine maintenance. No such parts within the REAL Immersive System will require inspection
nor maintenance by a service personnel to ensure basic safety during the one-year product lifespan.
Therefore, circuit diagrams and calibration instructions are not provided because service in parts repair are not necessary.
At the end of the one-year product lifespan, the user should dispose of the device through a safe environmentally electronic
waste recycle system.
Supply mains are electrically isolated in ME equipment to maintain basic safety.
INTENDED USE
The REAL Immersive System is an immersive virtual reality and display system that interactively displays and tracks upper-
extremity rehabilitation exercises for adult patients with conditions or symptoms associated with acute pain, cerebral palsy,
stroke, orthopedic, or neurodegenerative disease such as Parkinson’s, dementia, and Alzheimer’s, using a combination of
virtual environments and full presence tracked avatars for visual feedback. These rehabilitation exercises are intended to be
conducted in a seated position in a clinical environment and prescribed and supervised by a medical professional trained in
rehabilitation therapy.
CONTRAINDICATIONS
There are no known contraindications.
WARNINGS/PRECAUTIONS
Damage (mechanical and electrical) may result if the tablet, HMD, sensors, router, router battery, and/or sensor charger are
dropped or struck against another object.
Device is not intended for continued use if dropped from higher than 1 meter.
Do not touch the router and patient at the same time. Patients are not allowed to touch the router at any time.
IFU-133661 Revision 01 draft
During use, the surface of the equipment will not exceed 41 °C.
Do not use sensors near metal including, but not limited to, wheelchairs, walkers, and utility carts.
Headset tracking can be lost or compromised if large objects obscure the HMD.
To avoid risk of electric shock, this equipment must only be connected to a supply mains with protective earth.
At no time should liquid products be allowed near any device component.
Handle the lenses on the HMD carefully to avoid smears or scratches. Wipe lenses with a soft-lens cleaning cloth as needed.
Clean outer and inner plastic components of HMD with 70% or less isopropyl alcohol (IPA) wipe.
Do not use petroleum-based compounds, acids, caustics, or chlorinated solvents to clean or lubricate any parts. Use only water-
based solvents for cleaning.
No modification of this equipment is allowed.
Keep the original box and protective packaging for transporting components between locations or shipping purposes.
Use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment could
result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper
operation.
Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used
no closer than 30 cm (12 inches) to any part of the REAL Immersive System, including cables specified by the manufacturer.
Otherwise, degradation of the performance of this equipment could result.
Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper
operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are
operating normally.
Accessories such as power adapters and cords should not be replaced by the end user and should only be replaced by
Penumbra. Any changes or replacements of accessories will likely impact compliance of REAL Immersive System.
OPERATOR PROFILE
Operators of the REAL Immersive System should be trained in occupational or physical therapy.

Recommended separation distances between
portable and mobile RF communications equipment and REAL Immersive System
REAL Immersive System is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of REAL Immersive System can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and REAL
Immersive System as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m)
can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power
rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.

REAL Immersive System should assure that it is used in such an environment.

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
surveya, should be less than the
compliance level in each frequency
range.b
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which REAL Immersive System is used exceeds
the applicable RF compliance level above, REAL Immersive System should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating REAL
Immersive System.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
