THE DISPLAY SCREENS
The diagram below shows the various features that may be displayed on the
screens in the normal operating mode (receiver not in set-up mode).
Fig:1 THE PARTS OF THE NORMAL DISPLAY SCREEN
The RF Level Bars
The two upper bars display the RF signal strength for the two diversity
channels, labelled
A and B.
The Diversity Icons
Following the labels, to the left of these bars, are the diversity icons. One of
these will normally be displayed, indicating which RF signal is being used. If
the receiver squelch is active, the diversity icons are replaced by a single
rectangular block.
The Audio Level Bar
Below the RF bars is the audio level indicator bar, labelled AF.
The Transmitter Battery Status Indicator
The icon displayed in the top-right corner of the screen shows the status of
the transmitter battery. This icon indicates the battery status as 1 of 6 levels.
The Audio Monitoring Icon
When the ‘headphones’ icon is displayed in the bottom-right corner of the
screen, this indicates that the audio output from that receiver is routed to the
front-panel monitoring socket. Any combination of the four receiver outputs
may be simultaneously monitored.
In normal operating mode, alternate presses of the ‘
OK
’ button to the right of
the screen will add or remove the receiver audio output to the monitor
channel.
The Rack Supply Low Icon
If the power input to the rack falls below the pre-set level, the rack supply low
icon will be displayed in the bottom-left corner of the screen. This icon will
blink periodically. The input level which causes this warning to be displayed is
adjustable by the user via the set-up menus. This warning facility can also be
turned on or off via the set-up menus.
