2500 MMGL and 2500 YMGL Telephones

FLASH button

REDIAL button

HOLD button

MUTE button

Pressing and holding the MUTE button down blocks your conversation from being heard by the other party.

FLASH button

The FLASH button performs the same function as flashing the switchhook; that is, it provides access to system features or use of custom calling services that require a press of the switchhook.

REDIAL button

The REDIAL button is used to dial the last number dialed (up to 28 digits).

HOLD button

The HOLD button is used to put a call on hold. Below the HOLD button, there is a red light. When the user puts a call on hold, the light goes on.

Message light

The red Message light flashes when a message has been left, and flutters when a call is being received. The telephones recognize either LED or neon message waiting signals.

Positive Disconnect

The Positive Disconnect switch on the bottom of the telephone has two positions: ON and OFF.

The ON position hangs up the telephone for approximately two seconds, even if the switchhook depression is less. This prevents inadvertent switchhook flashes. To initiate switchhook flash in this mode, press the FLASH button.

In the OFF position, the switchhook will function normally.
