CURRENT=38/55/48%
* LOW BATTERY *

will be inhibited and the following screen message will be displayed:

5.21.7 BUZZ STOP Key
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.
5.21.8 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.
