Unable To Access Automated Systems
Automated systems used by banks, long distance voicemail and other
applications require that a phone be set to TONE dialing . Check the switch on the bot-
tom of the phone labeled TONE/PULSE and set to "T" . This will enable the phone to be
compatible with these automated systems .
If the power goes out, or the AC Adapter is not properly connected to the phone, the
amplification, extra loud ringer and the lighted keypad will not work . If you have backup
batteries installed, amplification will still work, but the phone will drain the backup bat-
teries very quickly . This will cause the need for the batteries to be changed frequently
and the Low Battery indicator light to constantly illuminate .

mended in areas of frequent power outages . This phone uses four alkaline batteries .
When installed and fully charged, the batteries maintain the high amplification for your
telephone .
