Troubleshooting
If after installing your IL40 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 accommo-
date compatibility with a variety of different tele phones.
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
hand set 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 mi cro 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 on a
different phone.
NOTE: The IL40 cannot be used on any telephone where the
keypad is located in the handset.
