Getting Started
Phone Signals
The IP Phones have several audio and visual signals to indicate feature activity. The following
are a few helpful tips:
Lit or blinking buttons indicate call or feature activity.
All phone button lamps illuminate at the same time for a few seconds when the IP phone
is reset or powered on.
The following actions may cause an error tone:
o Pressing an invalid button combination.
o Selecting a restricted feature.
o Dialing a restricted or invalid number.
o Dialing too slowly between digits.
o Waiting too long before performing the next step.
To correct an error tone, hang up and try again.
Many features “time-out” if you wait too long before performing the next step. If this
happens, you must start over.
“Off-hook” means the handset is lifted. “On-hook” means the handset is in the cradle.
If your IP phone does not have a lamp under the speaker button, the large message
indicator lamp on the top right of the IP phone indicates that the speakerphone is in use.
Comfort and Safety Tips
Observe the following comfort and safety tips when using the IP phone:
Do not cradle the handset: Prolonged use of the handset can lead to neck, shoulder, or
back discomfort, especially if you cradle the handset between your neck and shoulder. If
you frequently use the IP phone, you might find a headset more comfortable. “Using a
Headset” on page 8.
Adjust the viewing angle: The built-in stand tilts to give you a better view of the buttons.
See “Adjusting the Viewing Angle” on page 15.
Protect your hearing: Because prolonged exposure to loud sounds can contribute to
hearing loss, keep the volume at a moderate level. You can adjust the volume levels of the
handset receiver or headset. See “Changing Volume Levels” on page 16.
