Always unplug your telephone from the power source and from the
network before you clean it. Use a soft cloth dampened with mild
detergent.
WARNING: Failure to unplug the telephone before you clean it could
result in electrical shock.
Table 9 lists possible problems that you may encounter and the most
likely solutions. Where possible, each solution refers to the section in this
guide where you can find detailed information.
Table 9 Possible Problems
Possible Problem
My telephone has no dial
tone and the display panel
is blank.
My telephone has "locked
up."
Callers cannot leave
messages on my voice mail.
When I dial 9 or 8 to access
an outside line, the display
panel shows "All Ports
Busy."
After I call another user in
my organization, I hear a
tone but no ringing.
Suggested Solutions
Verify that the power cord is fully inserted in the
correct connector on the underside of the
telephone. Use the strain relief tab to prevent the
cord from becoming unplugged.
Verify that the Ethernet cables are connected and
that each cable is in the proper connection.
Remove and add power to the telephone by
unplugging the power cord at the electric outlet
and plugging it back in.
If the telephone is powered through a powered
Ethernet cable, make sure that power is applied to
the cable at its source.
Your telephone has lost the connection to the
system. Remove the Ethernet cord from the jack,
and then re-insert it into the jack.
Wait a few seconds. If the telephone display panel
still appears to be locked, disconnect the electrical
power for your telephone, and then plug it back in.
Your mailbox may be full. Log in to your voice mailbox
and delete some messages.
No outside lines are available. Try again in a few
minutes.
The other user may have the Hands Free feature
enabled. Begin speaking after you hear the tone. For
details, see Using the Hands Free Feature.
