The RF Monitor (Radio Frequency Monitor) gives detailed information about the RF connection of receiver devices such as the DSR700 V1/V2 or SR4x00s. It is only available for receiver devices (DSR700 V1/V2, SR4000, SR4500). If there is no receiver device at your wireless system then you can’t open the RF Monitor.
The user can open just one RF Monitor at once and can monitor one receiver at once. RF Monitor can only be opened if at least one HUB4000 Q is online at users wireless system. RF Monitor always records 5 minutes of RF levels of all AKG devices. If the RF Monitor is opened the last 5 minutes of RF levels of all AKG devices are available not matter when the RF Monitor was opened or which AKG device was active within the RF Monitor.

Select HUB4000 Q: The user can choose the HUB4000 Q of which he wants to monitor the receiver devices. By default the first HUB4000 Q is chosen. With the arrows the user can switch to the next or previous HUB4000 Q. If there is just one HUB4000 Q than the user can’t choose the HUB4000 Q.
Select AKG Device: The user can choose the AKG Device (receiver device such as DSR700 or SR4x00) that he wants to monitor. By default the first receiver device is chosen. With the arrows the user can switch to the next or previous receiver device. If there is just one receiver device than the user can’t choose the receiver device.
Rehearsal Graph: The Rehearsal Graph shows the RF antenna levels over time. It records the levels of the last 5 minutes. The user can start and stop the recording of the levels, zoom in and out, scroll through the recorded values.
Start Button: If clicked the Rehearsal Graph will start recording the antenna levels over time.
Stop Button: If clicked the Rehearsal Graph will stop recording the antenna levels over time.
RF Low LED: The RF Low LED above the RF Level Meter will remain lit permanently red if the DSR700 detects RF Low and shows "RF Low" at its display. That means that the RF level dropped below a certain threshold level.
RF Level Meter: Indicates the strength of the transmitter RF signal.
Antenna Active A LED: This LED will be yellow if the antenna A is active and the RF signal of antenna A is currently used. There is only one antenna active at one time.
Antenna Active B LED: This LED will be yellow if the antenna B is active and the RF signal of antenna B is currently used. There is only one antenna active at one time.

RF Low LED: The RF Low LED above the RF Level Meter will remain lit permanently red if the SR4x00 detects RF Low and shows "RF Low" at its display. That means that the RF level dropped below the squelch level.
User can reset the RF Low LED and the warning state at the SR4x00 with the Clear Button or the at the physical device itself. There are separate RF Low LEDs for both antennas.
RF Level Meter: Indicates the strength of the transmitter RF signal. As long as the RF level exceeds the selected Squelch Level (or threshold), the RF level meter will remain blue.
If the RF level drops below the squelch level, the upper part of the RF Level Meter will turn red for approx. three seconds indicating that the RF level was under the squelch level. The lower part of the RF Level Meter indicates always the RF level and is shown blue. If there was once a transmitter linked to the SR4x00, meaning that the SR4x00 has received a valid RF Signal at its selected RF Frequency, and the transmitter is then turned off the SR4x00 will show "TX OFF" on its display. To indicate that state that the SR4x00 lost the link to the transmitter the RF Level Meter shows "TX OFF" in red.
There is a separate RF Level Meter for both antennas.
Squelch Arrow: The Squelch Arrows beside the two RF Level Meters are indicating the current Squelch setting (They are always the same because there is only one squelch setting for one SR4x00). If the SR4x00 uses Tone Code Squelch (TCSQ) the Squelch Arrow will not be displayed and instead "TCSQ" is displayed. With a right-click on the Squelch Arrow control a context menu is opened where the user can set the Squelch. If the user selects a Squelch Level from -80dB to -100db the Squelch is set to this level and Tone Code Squelch is not used. If the user selects "TCSQ" then Tone Code Squelch is used.
Antenna Active A LED: This LED will be yellow if the antenna A is active and the RF signal of antenna A is currently used. There is only one antenna active at one time.
Antenna Active B LED: This LED will be yellow if the antenna B is active and the RF signal of antenna B is currently used. There is only one antenna active at one time.
Diversity Error LED: This LED turns red if SR4x00 detects a Diversity Error. The user can reset the Diversity Error LED and the warning state at the chosen SR4x00 with the Clear Button or the at the physical device itself.
Clear Button: User can reset the RF Low LED, the AF Clip LED and the warning state at the SR4x00 with a click on the Clear Button. All warnings at the SR4x00 will be cleared except the TX OFF warning. This is only supported for SR4x00 Firmware Version 1.22 and higher (Unsupported Features)!
