Congratulations on the purchase of your new FrontRow To Go™ active learning
system!

You may have heard the term ‘sound field’ used to describe technology that improves
classroom acoustics. Your FrontRow system fits under this category, but we call it
an ‘active learning system’ because the benefits affect much more than just sound.

Active learning 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 active learning 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.

Understanding Active Learning and its Benefits

IMPORTANT!

Be sure to charge your FrontRow ToGo 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

diagram 1

1 Setup Tips

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.

Fourth – Consider whether other
FrontRow ToGo, FrontRow Tempo, or
other radio-based active learning 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. See diagrams on
pages 40-41 for guidance.

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.

diagram 2

5

• 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.

Setup Tips (cont’d)

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 5
hours unplugged.

After each use –

• Turn transmitter power ’off’, and place it back onto the charging stand; con-
firm that the ‘charge’ indicator light illuminates. Transmitters not in use should
always be placed on the charging stand.

• Turn speaker column power ’of

f’. Leave speaker plugged into wall power out-

let, but confirm that the power has been turned ‘off.’

Battery care and maintenance tips –

• 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 acces

-

sible 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 925C charger will not charge
alkaline batteries. Never attempt to charge alkaline batteries – this will cause
damage to the unit and void the product warranty.

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!

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.

OptiVoice is a 3-position switch that
automatically adjusts the sound quality
of the primary speaker’s voice. It allows
teachers to shape the sound of their voice
and helps to ensure maxium speech clar­ity in low, medium and high noise levels.

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.

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 elec trical products,
MUST be treated with respec t. 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 elec tric
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

ELECTRICAL WARNINGS:

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 illustra­ tion below. Improper connection
can result in a risk of an electric shock.

This battery the receiver is for use on a
nominal 120 volt circuit (common
household current), and has a ground­ ing plug as illustrated. A temporary
adapter may be used, USA only, to
connect this plug to a two-pole recep­ tacle, as shown, if properly grounded
outlet is not available. The temporary
adapter should be used only until a
properly grounded outlet can be
installed by a qualified electrician.

55

DANGER - Before using adapter as illus­trated, be certain that center screw of outlet
plate is grounded. The green colored rigid
ear or lug extending from adapter MUST be
connected to a properly grounded outlet

- make certain it is grounded. If necessar y,
replace original outlet cover plate screw with
a longer screw that will secure adapter ear or
lug to outlet cover plate and make ground
connection to grounded outlet.

2. Avoid Abuse to the Receiver

o To reduce risk of electric shock, unplug
the receiver from outlet before
attempting any maintenance or clean­ ing. Turning off controls will not reduce
this risk.

o DO NOT disassemble the receiver.
Return the apparatus to Phonic Ear
Front Row for qualified service and
repair if service or repair is required.

Incorrect reassembly may result in a
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
Front Row 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 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
and an adaptor! The cord MUST be

plugged into a grounded outlet. Make
sure it is properly wired, in good elec­ trical 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 other­ wise 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.
