The “BUZZ STOP” key has no effect on the LCD screen display. However if the UPS alarm

buzzer is on, pressing this key will silence it. If the alarm buzzer is not on, pressing this key

has no effect.

6.18.8 RESET

Key

The RESET key function is used to 'Reset' the LCD display board software should a

system lock-up occur. The reset does not reset the variables in the memory. Use of the

RESET function is very important when a fatal communication error has occurred.

Press

and hold the RESET key for a period of at least five seconds to reset the display software.

The 'display board' to 'main board' interface will begin a new communication sequence. If a

communication response is not received by the 'display board' from the 'main board' within

15 seconds, a fatal time-out occurs and the following system message displays:

- DISPLAY ERROR -

MAIN COMM. ERROR

PRESS & HOLD RESET KEY

If the 'Reset' function is successful then the display will begin from the 'Start-up screen' and

then change to the 'main monitor' screen.
