默认消息亮度：显示消息的亮度可随此设置点而变化。当显示默认信息时，将使用此亮度。当：•出现报警•按下PQM键盘上的任意一个键•PQM关闭并打开•通过串行端口发送文本显示消息时，亮度默认为100%。当DEFAULT message TIME（默认消息时间）设置为off（关闭）时，自上次按下PQM键（假设不存在报警）后，5分钟后亮度调整至编程水平。如果未对默认信息进行编程，则当前信息将保持显示，并且在默认信息时间设定点中的编程时间过去后，显示屏亮度将调整至编程水平。
DEFAULT MESSAGE BRIGHTNESS: The brightness of the displayed messages can be varied with this setpoint. This brightness will be used when the default messages are being displayed. The brightness defaults back to 100% when: • an alarm is present • any one of the keys on the PQM keypad is pressed • the PQM is turned off and on • a text display message is sent through the serial port. When DEFAULT MESSAGE TIME is set to OFF, the brightness adjusts to the programmed level after 5 minutes have elapsed, since the PQM keys were last pressed assuming no alarm is present. If no default messages are programmed, the currently message remains displayed and the display brightness adjusts to the programmed level after the programmed time in the DEFAULT MESSAGE TIME setpoint has elapsed.
