Model 8520 User Guide
FINDING YOUR WAY
WHAT YOU SEE AND HEAR
As you can see, your Model 8520 and telephone system come equipped with many
features. To help you understand what everything means, it is recommended that you
read the following information before you use your endpoint:
• Your telephone system may be programmed for one or two dial tones. Systems
with two dial tones have one for intercom calls and one for outside calls.
• Many features “time out” if you wait too long before performing the next step. If
this happens, you must hang up and start over.
• If you hear four fast tones or repeating fast tones, you have pressed an invalid
button combination, tried to select a restricted line, dialed a restricted or invalid
number, dialed too slowly between digits, or waited too long before performing
the next step. Hang up and try again.
• Some endpoint models have red/green lamps in the feature buttons. Green indi-
cates a call is ringing, holding, or active on your endpoint. Red means the call is
on another endpoint. If the buttons only light red, either your endpoint does not
have the green lamps, or the system is not programmed to support the two lamp
colors.
NOTE: Your endpoint may be programmed to always use red lamps for calls ring-
ing directly to your endpoint. If you are uncertain about the configuration, ask your
system administrator.
• The button lamps may be solidly lit or flashing to indicate the status of a call or
feature. To avoid confusion, this guide uses different icons to signify that a lamp
is unlit ( ), lit, ( ), or flashing ( ).
• “Off-hook” means that either the handset is lifted or the speakerphone is on (
is
lit). “On-hook” indicates that the handset is in the cradle or the speakerphone is
off. For example, you must first go “off-hook” to make a call, but you must go
“on-hook” to end a call.
• If the button and Message Indicator lamp are lit when using a directory or
entering a message, you are in alphanumeric mode, which allows you to enter let-
ters. If the button and the Message Indicator lamp are unlit, you are in
numeric mode and can only enter numbers and special characters.
• “Handsfree” mode indicates that a call is connected through the speakerphone
(i.e., you don’t have to lift the handset to speak). While in handsfree mode, you
can make or receive calls.
