Key Description
Handsfree key - Activates Handsfree for making and receiving calls without
lifting the handset. When the audio mode option is set, this key is used to
switch between a headset and the handsfree speakerphone.
Mute key - Mutes the microphone so that your caller cannot hear you (the
light indicator flashes when the microphone is on mute).
Navigation keys - Pressing the UP and DOWN arrow keys lets you view
different status and text messages on the LCD display (if there is more than
1 line of status/text messages). These buttons also let you scroll through
menu selections, such as the Options List.
Pressing the LEFT and RIGHT arrow keys lets you view the different line/
call appearances. While in the Options List, these keys allow you to exit or
enter the current option. When you are editing entries on the display,
pressing the LEFT arrow key erases the character on the left; pressing the
RIGHT arrow key sets the option.
