The TOP VIEW includes the following:.
1) 9-volt Adapter jack (on top/rear side of telephone)
This round jack, located on the top/rear of the set and labeled DC 9V,
is used to connect a 9-volt adapter to the telephone. This adapter can
be used for improving the performance of the built-in speakerphone on
long loops in which there is limited power available from the line.
2) LINE jack (on top/rear side of telephone)
This jack, located on the top/rear of the set, is used to connect the
telephone and the modular wall jack. Use the 7-foot cord that comes
with the set.
3) DATA jack (on top/rear side of telephone)
This jack, located on the top/rear of the set, is used to connect a
device such as a modem to the telephone.
4) Ringer indicator/Message light
This indicator flashes when the telephone rings with an incoming call.
The light also flashes when you have a message.
5) Ten Memory-Dialing buttons
These 10 buttons, located at the top of the dial pad, provide easy
dialing of 20 frequently-dialed numbers. Each memory button can
store two separate numbers of up to 24 digits. (A pause or flash
counts as two digits.) In order to dial the number programmed on the
upper portion of each button (numbered 01 through 10), press the
button once; to dial the number programmed on the lower half of each
button (numbered 11 through 20), press the button twice.
6) SPEAKERPHONE button
Use the 2-way speakerphone for hands-free call-handling. When the
speakerphone is activated, the red light next to the button goes on.
7) MUTE button
When you press the MUTE button while speaking on the handset, the
handset's microphone is turned off. Use the Mute feature when you
want to confer with someone in the room with you, but you do not want
the other party on the call to hear your conversation. When the Mute
feature is activated, the red light next to the button goes on.
