Introduction
Congratulations on the purchase of your new FrontRow To Go sound field system!
Sound field systems can help engage students, improve attentiveness to the teacher,
build learning success, reduce the achievement gap, foster control and orderliness,
improve test scores, and reduce vocal strain and fatigue for teachers. Numerous
studies show that classrooms using sound field enjoy better student comprehension,
increased student participation, better grades and fewer behavioral referrals.
Read this manual carefully to become familiar with your system and to get the most
out of its many features and options.

Setup Tips
IMPORTANT!
Be sure to charge your FrontRow To Go speaker and transmitter units overnight – for
a minimum of 12 hours – before turning the power on and/or using them for the first
time. Failing to do so may reduce battery capacity.
Basic setup tips
First – Identify a front corner of the room – the location from where the teacher
normally teaches.
Second – Take a good look around, paying
close attention to power outlet and other
electronic equipment locations. Ideally, the
speaker should be placed at a 5 ft./1.5m
distance from other electronic equipment,
such as computers or radios.
Third – Determine whether to mount the
speaker on the wall as shown (diagram 1), or
place it on a sturdy surface using the table
stand (diagram 2). In either case, the speaker
3
diagram 1
Setup Tips (cont’d)
should be placed at a height of 3 ft./1m
from the floor, or at a level closest to the
listener‘s ears.
diagram 2
Fourth – Consider whether other
FrontRow To Go, FrontRow Tempo, or
other radio-based sound field systems are
in use in the building, and set transmitter
and receiver channels accordingly. Every
transmitter in a building should be on its
own channel.
If placing the speaker on a table
or surface top,
consider the following:
• Choose a location that provides easy access for the teacher, and is out of
the way of students and main traffic areas. The speaker should be placed at
least 6 ft./1.8m away from where the teacher stands.
4
Setup Tips (cont’d)
• Choose a table or surface top that is sturdy. Make sure the table or cabinet is
structurally solid, sturdy and out of the way of foot traffic.
• Properly mount and securely fasten the table stand onto the bottom of the
speaker. Make sure the stand is fully open and screwed on tightly, and that the
speaker does not wobble when in an upright position.
If mounting on the wall, consider the following:
• The power supply cord needs to reach the wall outlet. Make sure the power
supply is within reach of the speaker in its wall-mounted position.
• The teacher should be able to reach the controls located on top of the speaker
once it’s mounted. Once the volume is set at a comfortable level, the speaker
power switch located on the lower right side of the speaker can be easily accessed
by the teacher. Follow the instructions on page 32 for setting the volume at the
proper level.
• Never mount the speaker upside down, or horizontally. The speaker unit must
be mounted so the controls are located at the top of the unit.

Operating Tips
In the morning –
• Turn transmitter power ’on’ and put microphone on.
• Turn speaker column power ’on’. The speaker should remain plugged into
a wall power outlet during the day – with the power in the ‘on’ position. Turn
power switch to the ‘off’ position at night after each use. The internal battery is
not being used while the speaker is plugged into a wall outlet.
• To operate using the internal battery as a portable system, simply unplug
the speaker before use and plug back in after use. The battery takes 8 hours to
reach a full charge; at full charge, the speaker column battery will last up to 6.5
hours unplugged.
After each use –
• Turn transmitter power ’off’, and place it back onto the charging stand; confirm that the ‘charge’ indicator light illuminates. Transmitters not in use should
always be placed on the charging stand.
• Turn speaker column power ’off’. Leave speaker plugged into wall power outlet, but confirm that the power has been turned ‘off.’
6
Operating Tips (cont’d)
Battery care and maintenance tips –
• To maximize your battery operating time, "cycle" the battery (fully charge and
fully discharge) five times during initial use.
• The speaker battery will last approximately 2 years depending on usage.
• When not in use, leave speaker plugged into wall outlet with power switch in
‘off’ position.
• Keep speaker away from heating units – use/store in a cool dry place.
• When using speaker battery power (unplugged from wall), always remember to
return power switch to ‘off’ position after use.
• Never mount/use speaker horizontally or upside down. Controls should be accessible from top of unit.
• Remember to charge all rechargable batteries overnight before initial use.
• Plan on buying new NiMH batteries for your transmitter every 12 months. Alkaline
batteries can also be used as back-ups, however, the 923C charger will not charge
alkaline batteries. Never attempt to charge alkaline batteries – this will cause
damage to the unit and void the product warranty.
7
Operating Tips (cont’d)
Do not coil the microphone cord – since it also acts as your antenna, coiling
or wrapping the cord around the transmitter will affect its range and may also
reduce its life.
Speak at a normal level – the system is projecting your voice for you!

Using Your System (cont’d)
Follow steps 1 or 2 below to adjust
FM volume setting to proper level. Two
people are needed to set the volume
level. It is difficult to hear your own voice
and make adjustments to it.
NOTE: The average volume setting is
in the 3 position (see photo), but may
change depending on room acoustics and noise level.
1. With a sound level meter - Take a level reading in the center of the room during
normal classroom activity, and another reading of the teacher's amplified voice (without
the class activity). The level of the teacher's voice should be set between 10 -15 decibels
above room noise level.
2. Without a sound level meter - First, ask someone other than yourself (if you are the
teacher) to listen to the amplified voice and make volume adjustments. An ideal volume
level is achieved when the listener can hear the amplified voice at a comfortable level and
the volume level from the speaker and teacher’s mouth is comparable. If you can hear
yourself through the loudspeakers, the volume setting may be too high and should be
decreased.

Using Your System (cont’d)
1. Set OptiVoice switch according to
room noise level. Medium position is the
recommended setting for average noise
levels.
Low: Use in low-noise situations and for
most natural voice reproduction.
Medium: Best setting for average classrooms where low-medium noise levels are present.
High: Use in high noise levels. Helps to ensure top comprehension during critical tasks
such as test-taking or hearing impaired instruction.
NOTE: With each increase in level, there is an increase of approximately 3dB in gain
(volume). This may require a decrease in the receiver volume setting to avoid potential
microphone/speaker feedback.

PRECAUTIONS & SAFETY
RECOMMENDATIONS
Follow Manufacturers' Recommendations
Before using the receiver, read all instructions
and caution markings on the receiver and in
this user guide.
ELECTRICAL WARNINGS:
DANGER! RISK OF ELECTRICAL AND
FIRE HAZARD. MAY RESULT IN DEATH,
SERIOUS INJURY, SHOCK OR BURNS.
TO HELP REDUCE THIS RISK:
This receiver, like all electrical products,
MUST be treated with respect. Follow these
instructions to reduce electrical hazard risk.
1. PROPER GROUNDING AND
AC POWER CONNECTION
o The receiver MUST be grounded to
reduce risk of electric shock. The
receiver is equipped with an electric
cord having an equipment grounding
conductor and a grounding plug.
The plug MUST be plugged into an
outlet that is properly installed and
GROUNDED in accordance with all
local codes and ordinances. If you
ever feel even a slight shock from this
or any electrical appliance, stop, walk
away. Turn off electricity to outlet, and
have it inspected by an electrician.
You may have a dangerous,
improperly wired outlet.
o DANGER - NEVER alter AC power
cord or plug provided - if it will not
fit in the outlet, have proper outlet
installed by a qualified electrician
or proceed as shown in the illustration below. Improper connection
can result in a risk of an electric shock.
2. Avoid Abuse to the Receiver
o To reduce risk of electric shock, unplug
the receiver from outlet before
attempting any maintenance or cleaning. Turning off controls will not reduce
this risk.
o DO NOT disassemble the receiver.
Return the apparatus to Phonic Ear
FrontRow for qualified service and
repair if service or repair is required.
Incorrect reassembly may result in a
56
ELECTRICAL WARNINGS: (cont'd)
risk of electric shock or fire.
o DO NOT expose the receiver to rain,
snow, water, gas, oil, etc.
o DO NOT operate the receiver if it has
received a sharp blow, been dropped,
or otherwise damaged in any way;
return the apparatus to Phonic Ear
FrontRow for qualified service and
repair.
o DO NOT block or cover the apparatus
and impeded ventilation.
3. Proper Use of The receiver and Wiring
o Always use the supplied power cord.
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. If extension cord must be
used, use ONLY a grounded, 3-wire
type cord. NEVER use a 2-wire cord
57
and an adaptor! 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 receiver as specified below.
AWG = American Wire Gauge
o To reduce risk of damage to plug
and cord when disconnecting the
receiver, ALWAYS pull on plug NEVER on cord.
o 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 battery or
the receiver. DO NOT operate the
receiver with damaged cord or plug replace them immediately.
o Allow continued easy access to the
power cord thus allowing continued
easy interruption of main supply to
the system by removing the plug from
the main wall socket.
