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.
Installation
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
Amplifier.
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.
