ALARM/ZOOM/FREEZE Operation
1.ALARM Feature
•When an alarm occurs, all functions of the monitor are temporarily paused and the monitor switches to the Alarm Display mode.
•When an alarm trigger is received, the corresponding channel will be displayed in Single Display mode with the letter "A" shown at the bottom left of the full screen.
•When more than one alarm occurs, the monitor will automatically switch to Quad Display mode and the letter "A" will be displayed at the bottom left quadrant of the corresponding channels.
•While in the Alarm mode, you can still change the screen by using the MODE and CH keys. However,you will not be able to set up Zoom, Freeze, and Menu.
•While in the Alarm mode, if the ALARM RESET key is pressed or the Alarm Hold Time has elapsed, all Alarms will be cancelled and the monitor will switch back to the previous mode.
•If an alarm cable is connected between a monitor and a VCR, both Alarm and Reset signals output from the monitor will become input signals for the VCR.
