Five quick reference cards are provided in the tray located under the base of
every 6400 Series telephone.
Handset
The 6424D+ and 6424D+M telephones are equipped with an AJ2A handset which
can accept either a handset or a headset.
Dial pad
The 6424D+ and 6424D+M telephones are equipped with a 12-button touch-tone
dial pad. The letters “Q” and “Z” have been added to the appropriate dial pad keys
for directory access, and the “5” button on the dial pad has raised bars for
visually-impaired users.
Jacks
The housing of the 6424D+ and 6424D+M telephones has a Line jack and a
Handset cord jack located on the back of the housing. The 6424D+ also has an
Expansion Module (“XM24”) jack on the back of the telephone to allow connection
of an XM24 expansion module.
The Modular 6424D+M telephones also have a Headset jack on the back of the
telephone. The Handset cord jack can be used for either a headset or a handset;
however, the Headset jack can be used only with a headset.
NOTE:
When a modular base unit is used with the Headset jack, the handset
should remain plugged into the Handset jack.
NOTE:
If you plug the headset directly into the Headset jack, you may use a button
on the adapter cord, if so equipped, to go off-hook and on-hook, or a
button may be administered.
Cords
Two cords are supplied with all 6424D+ and 6424D+M telephones: a coiled 9-foot
handset cord and a 7-foot line cord.
Optional longer cords are available: a 12-foot handset cord and 14-foot and
25-foot line cords.
In order for the tip/ring module to operate with the Modular 6424D+M telephone,
the telephone’s desktop stand and the required auxiliary power supply must be
connected with an 8-foot D8W cord.
