VoiceStation™ 500 - 16
Maintenance
Troubleshooting
Clean the VoiceStation™ 500 with a soft, dry cloth.
Do not use alcohol- or petroleum-based cleaners.
Muffled or “In a Well”
Reception
► Speak closer to the phone so that
the microphones pick up your
speech more accurately.
► Add more sound absorbency to the
room.
Excessive Noise
► Noisy equipment such as a com-
puter or fan may make it difficult to
hear the other party. Both parties
should turn off noisy equipment.
► Try calling again to see if a differ-
ent line provides a better connec-
tion.
Physical Damage
► If physical damage is severe
enough that the internal parts
become visible, disconnect the
VoiceStation™ 500 immediately.
► Do not reconnect to the network
until the VoiceStation™ 500 has
been repaired.
No Dial Tone
► Check that all connections are cor-
rect and tight.
► Make sure the short cable is con -
nected to a standard analog phone
line.
► Try a different telephone line.
Phone Does Not Ring
► Adjust the Ringer with the Volume
up button.
Short Silences, Echoes, or
Clipped Speech
► Do not move VoiceStation™ 500
while it is in use.
► Keep your hands away from the
phone during calls.
► Keep papers, cups, coffee pots, and
other objects away from the phone.
► At the beginning of a call, allow
each speaker present to speak in
turn for a few moments to enable
the phone’s electronics to adjust to
the acoustic environment.
► The other party may be using low
quality equipment or a half-duplex
conference bridge, in which case
there is no solution.
