Alert Level
When 3 is selected from the Service Diagnostic menu, and the correct password had been entered, the
Alert Tone Level may be adjusted. The alert tone level is adjusted by using the scroll keys to increase or
decrease the tone level. The available adjustment levels are –15 dB to 0 dB in –3 dB increments.
Page Level
When 4 is selected from the Service Diagnostic Menu, and the correct password had been entered, the
Page Tone Level may be adjusted. The page tone level is adjusted by using the scroll keys to increase or
decrease the tone level. The available adjustment levels are –15 dB to 0 dB in –3 dB increments.
Security
When 5 is selected from the Service Diagnostic Menu, you are prompted to select the desired security
level using the numeric keypad. No security is useful during initial set-up and installation so the
password is not required while adjusting line levels and other levels. The highest security level provides
complete restriction to the console diagnostics and user adjustments.
