Troubleshooting
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.
