Set Info
The Set Info menu displays the firmware version for the IP Phone and any
attached LCD Expansion Module. The attached LCD Expansion Modules
are identified as KEM1, KEM2, KEM3, and KEM4. KEM1 is the closest to
the IP Phone. The KEM identifies the firmware as a three character string;
the TPS displays the firmware in an n.nn format.
Use the Up or Down navigation keys to scroll the list to display the
firmware for each attached LCD Expansion Module. The firmware version
appears even if the LCD Expansion Module is not configured in LD 11. In
this case, the LCD Expansion Module is identified in the display area by an
asterisk (*) after the KEM number (for example, KEM1*).
If a LCD Expansion Module is configured but does not respond, the
firmware version displays as <unavailable>.
