Additional Information
Your Epic telephone will light up its line status
indicators when a non-EPIC telephone such as a
fax machine, modem, or standard telephone is
using a line.
Note: If the line status indicators of your EPIC
telephones do not function properly, either failing
to light up when a standard telephone uses a
line, or staying lit even though no telephone is
using a line, then the loop voltage detector set-
ting needs to be adjusted.
The factory setting of 48 volts is appropriate for
most installations. If this is not suitable, try set-
ting your phone to 24 volts, and if that does not
work, then set it to 12 volts. You can also turn
this feature OFF if you prefer.
If a line indicator at your EPIC telephone stays lit
because there is no telephone line connected,
and you wish to turn it off, do not use this feature.
Instead refer to page 19 and set this unconnect-
ed line at this station to UNCONNECTED.
