1. Avoid Abuse to the Power Supply
To reduce risk of electric shock, unplug
the power supply from outlet before
attempting any maintenance or cleaning.
Turning off controls will not reduce this risk.
DO NOT disassemble the power supply.
Return the apparatus to FrontRow for
qualified service and repair if service
or repair is required. Incorrect reassembly
may result in a risk of electric shock
or fire.
DO NOT expose the power supply to
rain, snow, water, gas, oil, etc.
DO NOT operate the power supply
if it has received a sharp blow, been
dropped, or otherwise damaged in any
way; return the apparatus to FrontRow
for qualified service and repair.
DO NOT block or cover the apparatus
and impede ventilation.
2. Proper Use of the Power Supply
and Wiring
An extension cord should not be used
unless absolutely necessary. Use of
improper extension cord could result
in a risk of fire and electric shock. The
cord MUST be plugged into a grounded
outlet. Make sure it is properly wired, in
good electrical condition, and wire size
is large enough for AC ampere rating of
the power supply or charger as specified by
FrontRow. AWG = American Wire Gauge.
To reduce risk of damage to plug and
cord when disconnecting the power
supply or charger, ALWAYS pull on plug
- NEVER on cord.
Locate cord so that it will not be
stepped on, tripped over, or otherwise
subject to damage or stress. DO NOT
lay extension cord on charger.
DO NOT operate the power supply
with damaged cord or plug - replace
them immediately.

1Installation
Before you begin your installation
Make sure you've got everything you need to set up your FrontRow Symbio system.
By taking a few minutes to prepare, you'll help ensure the actual set-up is as quick and
problem-free as possible.
General safety precautions
• Do not install or use the receiver near water or heat sources
• Clean only with a dry cloth
• Do not block any ventilation openings
• Protect all cables from wear and damage from foot traffic, doors, and other hazards
• Use only accessories specified by FrontRow
• Refer servicing to qualified service personnel
• Wear safety goggles when using power tools
• Follow all safety guidelines when using ladders
• Observe your local building, electrical, and fire codes when installing any
electrical equipment
Does your system meet the classroom requirements?
Check the table below to confirm that your classroom is set up properly for the
Frontrow Symbio system you have. In most cases one ceiling sensor will be suf-
ficient. However, some classrooms may require one or more additional sensors for
optimal room coverage. While other classroom configurations may work with your
Frontrow Pro Symbio system, we can only support those listed below.

Are your existing speakers a feedback risk?
It's very important to assess the position of existing speakers — and move them if necessary — to
avoid creating acoustic feedback. Confirm before your begin that your speakers are positioned
according to these guidelines:
a Installing ceiling speakers?
Install speakers only over the area where students are sitting — not the entire room.
Avoid installing speakers directly in front of the white board — this not only covers an
area not used by students but increases the chance of feedback.
Each speaker fully covers
one-fourth of student
listening area
Avoid covering area in
front of white board
Install speakers in ceil-
ing tiles centered over
one-fourth of the stu-
dent listening area
Correct
✔
Inadequate coverage of
student listening area
Too much coverage in
front of white board
(feedback risk)
Incorrect
✘

b Installing IR speakers?
Install speakers only over the area where students are sitting — not the entire room.
Speakers should only be placed on the side walls of the classroom.
Walls should have a space approximately 10in wide by 5in tall (25 x 13cm) to solidly mount the
wall bracket.
Avoid installing speakers directly in front of the white board — this not only covers an area not
used by students – but increases the chance of feedback.

SENSOR & SENSOR CABLE
The sensor and sensor cable are critical elements in the system and the most
sensitive to electrical noise.
a. DO NOT shorten OR lengthen the sensor cable. Its factory-specified length is
critical to the performance of the system.
b. DO NOT use a splitter with the sensor cable.
c. DO NOT use a different cable.
d. DO NOT alter the RCA connectors on the cable.
e. AVOID routing the sensor cable next to other cables or electrical systems (e.g.,
other electrical conduit, Ethernet cable, video cable, fluorescent light ballast, etc.).
Leave at least 6 in. (15cm) space around the sensor cable.
f. Excess cable can be coiled, tied and placed safely in a plenum space. DO NOT
place the sensor coil near other cables or electrical systems (e.g., other electrical
conduit, Ethernet cable, video cable, fluorescent light ballast, etc.).
g. Route the sensor cable AWAY from speaker wires as far as practical. We
recommend leaving at least 6 in. (15cm) between the two whenever possible.
h. Local regulations may require plenum-rated cable if used in a plenum space.
Sensor cable supplied with your system is plenum rated.
4 Plan Your Sensor Installation
(Skip this section if FrontRow IR speakers have been installed previously)
Sensor Mounting
Assessing the individual characteristics of the environment is critical to achieving the
best performance. Poor coverage planning can dramatically reduce the performance
of the system.
a. DO NOT mount the ceiling sensor or wall sensors in direct sunlight as it will greatly
reduce performance.
b. The ceiling sensor must have a clear view of the coverage area and must be
mounted parallel to the floor to function optimally (figure 1). If drop lights are used
in the room, wall sensors may be a better option. Or, a drop mount* may be used to
lower the ceiling sensor.

Plan Your Sensor Installation (cont.)
Interference and IR Coverage
The FrontRow Symbio system uses infrared light to transmit the voice signal from the microphone
to the sensor in the ceiling/wall sensors. Proper placement of the sensors is critical for optimal
system performance.
a. Adjacent classrooms that use FrontRow infrared systems can interfere with each other if the
rooms are separated by windows. The windows allow the infrared light to “escape” from the
classroom only to be picked up by the sensors in the adjacent classroom, causing interference
and “cross talk”. Be sure to recommend window coverings to the greatest extent practical
when using the system.
b. Direct sunlight can reduce system performance. Be sure to recommend window coverings to
the greatest extent practical when using the system.
c. Infrared light has better reflection off of white and glossy surfaces. The ceiling sensor can be
placed to help provide coverage in areas where the signal may be weak due to insufficient
infrared reflection.

Installing one ceiling sensor
Mentally divide the room into quarters and locate the center of the room as shown.
Use a piece of tape to mark a spot on the ceiling in the center of the room.
NOTE: The sensor must be able to "see" the entire room — do not block the sensor
with projector mounts, lighting, hanging art, or other obstructions. If the teacher can
see the sensor from all parts of the room, you've probably chosen a good spot.

Installing two ceiling sensors
Mentally divide the room into half and locate the center of each half as shown.
Use a piece of tape to mark the spots in each half of the room.
NOTE: The sensor must be able to "see" the entire room — do not block the sensor
with projector mounts, lighting, hanging art, or other obstructions. If the teacher can
see the sensor from all parts of the room, you've probably chosen a good spot.

2. Positioning wall sensors
Installing 2 wall sensors
Use a piece of tape to mark a spot for each sensor as shown below. One near the back corner,
one near the front corner.
The sensors should be positioned on the side walls relative to whiteboard/main
lecture area at right angles to the board.
Be sure they are in a position such that the teacher can see at least one sensor from all
parts of the room.

IMPORTANT!
DO NOT ALTER THE IR SENSOR CABLE
Read the FrontRow Installer Guide thoroughly
before installing sensor cable. The cable has
been rigorously tested and qualified to work
with your FrontRow IR sensors.
• Do NOT shorten
• Do NOT alter or replace the RCA connectors
• Do NOT "splice" or split the cable
• Do NOT use a "Y" adaptor
• Do NOT use any other type of cable
Altering the cable in any way will result in
decreased performance of your system and will
void your Manufacturer's Limited Warranty.
