Using Other Function Keys - AT&T 2U20 Instruction Booklet

Using Other Function Keys

REDIAL/PAUSE Key
To call the last number dialed, press the Redial/Pause
key while the portable unit is turned on.
To insert a 3 second pause in a memory dialing
sequence, press the Redial/Pause key when entering
a number into memory storage.
Partner System users: Note that the Cord-Free Headset's
Redial key may not be effective if the last number dialed
was for an outside call. In this case, use the Partner
System's Last Number Redial feature by pressing # 0 5.
MUTE Keys
In the mute mode, a caller will be unable to hear you,
but you will be able to hear the caller.
To mute the headpiece microphone, press and release
one of the MUTE keys. The ON/OFF/MUTE indicator
will flash when the headpiece is in this mode.
To turn the mute mode off, press one of the MUTE keys
again. Once the mute mode is disabled, the caller will
once again be able to hear you and the ON/OFF/MUTE
indicator will cease flashing, but remain lit.
CHNL Key
If you experience interference during your phone
conversation, press the CHNL key to select a new,
clear channel.
If the portable unit is out of range or no other channels
are clear, the portable unit will beep twice and
remain unchanged.
FLASH Key (Home Office Use)
If you subscribe to special services from your phone
company, (e.g.; call waiting), you may use the FLASH
key to access these services.
