9 Function Description
The Environment Scan function turns the receiver into a spectrum analyzer. UNLIMITED SCAN auto-
matically searches the receiver's entire frequency band ±6 MHz for active radio frequencies. LIMIT
SCAN scans only part of the receiver’s frequency range. During the search, the audio output is muted
and the display shows a frequency graph.
• You can navigate (CW, CCW) and zoom (push) through the graph using the SELECT control.
The Rehearsal Scan function converts the receiver to an RF recorder to check the transmitter RF level
in your reception area. Maximum recording time is four minutes.
1. Start this function and walk around the desired coverage area with the synchronized transmit-
ter. The graphic display indicates the received signal level as it varies over time.
2. To mark some positions, you can use the transmitter MUTE button to set markers on the re-
ceiver display.
• You can navigate (CW, CCW) and zoom (push) through the graph using the SELECT control.
• The received signal level should never drop below -85 dBm. You can optimize signal reception
by changing the position of the connected antennas.
The STATUS sub-menu lets you activate a visual warning that alerts you of selected critical system
conditions. If one of the selected conditions occurs, the LED ring around the SELECT control will
change from green to red and a warning message will appear on the display that describes the prob-
lem condition. The warning messages appear in the order of priority.
The LED ring is lit red and a large warning message displayed for 5 secs or as long as the fault con-
dition lasts.
A small warning message is displayed until the warning is confirmed.
The selected warning functions are active in LOCK and ACTIVE modes.
• To delete a warning message from the display, press the SELECT control briefly.
LOW BATT: The transmitter’s remaining battery capacity is low. A large warning message is dis-
played permanently and the LED ring is lit red.
AF CLIP: Audio overload in transmitter A/D converter. The LED ring is lit red and a large warning mes-
sage displayed for 5 secs. or as long as the fault condition lasts.
A small warning message is displayed in the main window until the warning is confirmed.
• Reduce the audio input level.
RF LOW: The field strength of the received RF signal is so low that the receiver’s audio output is
muted to prevent unwanted noise. The LED ring is lit red and a large warning message displayed
for 5 secs. or as long as the fault condition lasts.
A small warning message is displayed in the main window until the warning is confirmed.
ANT ERROR: The same antenna has been active for at least one minute. The LED ring is lit red and
a large warning message displayed for 5 secs.
A small warning message is displayed in the main window until the warning is confirmed.
• Check if an antenna cable is broken or incorrectly connected.
