SAVE THESE INSTRUCTIONS
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.
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.
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
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
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)
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.

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-

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-
