Other Physical Features
(on All of these 2500 and 2554 Telephones)
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.
Handset
All of these 2500 Series telephones are equipped with a K-type handset.
Dial Pad
All of these 2500 Series telephones are equipped with a 12-button touch-tone dial
pad. On all telephones, the letters “Q” and “Z” have been added to the appropriate
dial pad keys, and the “5” button on the dial pad has raised bars for
visually-impaired users.
Jacks
All of these 2500 Series telephones contain two jacks. The handset cord jack is on
the left side of the telephone. (The handset also contains a jack for the other end
of the handset cord.) The line cord jack is on the right rear of the set.
