Using the Hold Feature
The “HOLD” key is used to place a caller
on hold. To use, simply press the “HOLD”
key. The LED above the HOLD key will
illuminate to indicate that the line is on
hold. The LCD will display the word
“HOLD” when active.
When the “HOLD” key is active, the
handset can be lifted off-hook or returned to
its on-hook position and the line will not be
disconnected. To return to the caller,
simply lift the handset and the
“SPEAKER” key will automatically
activate for hands-free operation
.
Hold will also release when the call is
picked up from an additional extension
phone.
