Services key operation 187
If you configure four LCD Expansion Modules in LD 11 but two LCD
Expansion Modules respond, the TPS assigns keys 32 to 79 to the first
two LCD Expansion Modules. An error message alerts the administrator
that the hardware configuration does not match the administered
configuration. When a third LCD Expansion Module is detected, the TPS
changes the key assignments to display across all three LCD Expansion
Modules.
Services key operation
Use the Services key to access user settings and certain features on the
IP Phone. When one or more LCD Expansion Modules are attached to
the IP Phone, the actions of the display diagnostics for the IP Phones
DN/feature key display area are duplicated for the LCD Expansion Module.
If an incoming call occurs when in the diagnostic mode, answer the
call by pressing the DN feature key, handsfree, or headset key, or by
picking up the handset. The display area remains in diagnostic mode until
either you exit the diagnostic more, or the idle timeout clears the mode.
Once cleared, the normal display for the current state of the IP Phone is
displayed.
For information about the Services menu, see “Services menu” (page
143) for the IP Phone 1220 or “Services menu” (page 161) for the IP
Phone 1230.
