Shortel IP 230 PABX IP phone.

• LCD 141 columns by 44 rows, but not a straight-forward graphic LCD display. Really more like a character LCD display in that the character positions and size are predetermined and fixed, and there is not a continuously addressable graphics area.

The phone can be powered from 33V across the bridge rectifier outputs.

The are a number of built in test/setup functions obtained by pressing mute then a series of numbers representing the function names:

• 3424# (DIAG)
• 4636# (INFO)
• 7464# (PING)
• 73728# (RESET)
• 772667# (RRAMOS), factory reset, at the prompt enter 1234 as password
• 73887# (SETUP)
