Power Requirements

Your IL30/IL40 is powered by a 9V

battery (not included). Install a 9V
battery in the battery compartment
prior to operation.

NOTE: Insert the battery with the
(+) side going between the guard
posts in the battery compartment.
The (-) side (larger of the two con-
nectors on the battery) must be on
the top. Installing the battery im-
properly will cause damage to the
unit and will void all warranties. Please make specific note to
the installation of the battery.

Important: Before replacing the battery, make sure to
disconnect the IL30/IL40 from the telephone.


1. Unplug the handset cord from your

telephone base. Insert this cord into
the jack mar ked “HANDSET”
located at the front of the IL30/IL40

2. Plug one side of the short phone

cord (included) into the jack marked
“BASE” on the back of the Amplifier.

3. Plug the other side into the telephone

base (See Figure 2).

4. Set the Compatibility Switch to the “N” setting. This

setting provides compatibility for most telephones. (See Figure 1)

5. Pick up the handset. If you hear a dial tone, your IL30/IL40

Amplifier is installed properly.

If you do not hear a dial tone or the person you are calling
cannot hear you, consult the Troubleshooting Guide on page 5.

 Volume Control

You can adjust the volume level by using the Volume Control

Slide located on the top of the unit (left control).  Pushing the slide
up increases the volume.

 Tone Control

You can adjust the tone by using the Tone Control Switch lo-

cated on the top of the unit (right control). The Tone Control shapes
the sound by increasing the bass or the treble. The Tone Control
Switch has five (5) positions. Adjust the Tone Control until you find
a position that provides the clearest sound.

 Boost Switch (for IL40 only)

If you require additional amplification at any point in your conver-

sation, for IL40 only simply press & hold the Boost Button located on
the top of the unit. When the Boost Button is pressed, the micro-
phone in the handset is muted. This eliminates background noise
and feedback. Release the Boost Button when you want to speak.
The other party cannot hear you when the Boost Button is pressed.
Simply press & hold the Boost Button again, when you want
additional amplification.

 Battery Indicator

The battery indicator light comes on each time you pick up the

handset to indicate the battery level is ok. If the indicator light does
not come on, the battery must be replaced.

Important: Before replacing the battery, make sure to
disconnect the IL30/IL40 from the telephone

If after installing your IL40/IL30 Amplifier, you do not have a

dial tone or the person you called cannot hear you, take the
following steps:

1. Check that all connections are plugged in properly

2. Make sure a new battery is installed.

3. Either disconnect the unit or use another phone and check that

your phone service is working properly.

4. Change the compatibility setting dial located on the bottom of

the unit. (See Figure 1 Page 3)

Telephone Compatibility

Because not all telephone handsets are wired in a standard

way, we have provided a 12-position compatibility switch to
accommodate compatibility with a variety of different telephones.

If you do not hear a dial tone or the handset microphone does

not work at the “N” setting, you will need to adjust the switch until
you find the correct compatibility setting for your phone.

To adjust the compatibility switch:

1. Press & hold the “on-hook” switch on your telephone or place

the handset in the cradle.

2. Adjust the switch by turning it one “click” to the next setting.

3. Release the “on-hook” switch or pick up the handset and listen

for a dial tone.

Continue this process until you hear a dial tone and the micro-

phone is functional. Once you have located the proper setting,
make a note of it in the event it is changed accidentally or you use
your IL40/IL30 on a different phone.

NOTE: The IL30/IL40 cannot be used on any telephone where
the keypad is located in the handset.

Regulatory Compliance

Part 68 of FCC Rules Information

This equipment complies with Part 68 of the FCC rules and

the requirements adopted by the ACTA. On the bottom of this equip-
ment is a label that contains, among other information, a product
identifier in the format US:AAAEQ##TXXXX. If requested, this
number must be provided to the telephone company. A plug and
jack used to connect this IL30/IL40 to the premises wiring
and telephone network must comply with the applicable FCC Part
68 rules and requirements adopted by the ACTA. A compliant tele-
phone cord and modular plug, RJ11C USOC, is provided with this
product. It is designed to be connected to a compatible modular
jack that is also compliant. See installation instructions for details.
The REN is used to determine the number of devices that may be
connected to a telephone line. Excessive RENs on a telephone
line may result in the devices not ringing in response to an incoming
call. In most, but not all areas, the sum of RENs should not exceed
five (5.0). To be certain of the number of devices that may be
connected to a line, as determined by the total RENs, contact the
local telephone company. For products approved after July 23,
2001, the REN for this product is part of the product identifier that
has the format US:AAAEQ##TXXXX. The digits represented by
## are the REN without a decimal point (e.g., 03 is a REN of 0.3).
For earlier products, the REN is separately shown on the label. If
this telephone equipment, the  IL30/IL40 amplifier, causes harm
to the telephone network, the telephone company will notify you
in advance that temporary discontinuance of service may be re-
quired. But if advance notice isn’t practical, the telephone com-
pany will notify the customer as soon as possible. Also, you will be
advised of your right to file a complaint with the FCC if you believe
it is necessary. The telephone company may make changes in
its facilities, equipment, operations or procedures that could af-

 This telephone

equipment is not intended to be repaired and it contains no repairable
parts. Opening the equipment or any attempt to perform repairs will
void the warranty. For service or repairs, call 1-800-965-9043.
Connection to party line service is subject to state tariffs. Contact
the state public utility commission, public service commission or
corporation commission for information.


 If your home has specially wired alarm equipment

connected to the telephone line, ensure the installation of this  IL30/
IL40  does not disable your alarm equipment. If you have ques-
tions about what will disable alarm equipment, consult your
telephone company or a qualified installer.”

This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the in-
structions, may cause harmful interference to radio communica-

Before installing this equipment, users should ensure that it is

permissible to be connected to the  facilities of the local telecom-
munications company.  The equipment  must also be installed us-
ing an acceptable method of connection.  In some cases, the
company’s inside wiring associated with a single line individual
service may be extended by means of a certified connector as-
sembly (telephone extension cord).  The customer should be aware
that compliance with the above conditions may not prevent degra-
dation of service in some situations.

Repairs to certified equipment should be made by an autho-

rized Canadian maintenance facility designated by the supplier.
Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications com-
pany cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical

ground connections of the power utility, telephone lines and inter-
nal metallic water pipe system, if present, are connected together.
This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections

themselves, but should contact the appropriate electric inspection
authority, or electrician, as appropriate.
