PILOT.“P”.keeps.flashing.for.Receiver.Module.when.transmitter.power.switch.is.turned.on
Pilot tone detection can take several seconds. Turn on the
transmitter power (and the audio switch on some models) and wait
3 to 5 seconds for the “P” to indicate steadily.
Observe the RF Signal Strength Meter on the Receiver Detail Screen.
If the there is little or no RF, then the problem is RF-related. If there is
plenty of RF, then the transmitter and receiver are not on the same
frequency, or there may be a compatiblity mode mismatch.
Noise.on.audio.and.Pilot.indicator.is.“b”.
The pilot tone/squelch bypass has been activated. Set PilotBP for
selected Receiver Module to NORMAL.
Pilot.indicator.not.present.but.audio.is.being.received
Receiver Module is set to a Compatibility Mode that doesn’t use pilot
tone. Check that the Receiver Module’s Compatibility Mode matches
the associated transmitter as any sufficiently strong signal can
unsquelch the receiver in this mode, compatible or not.
.
Note
:.In Digital Hybrid (400 Series), 200 Series and IFB compatibility modes, the PILOT indicator on the front panel
shows as a solid “P” to indicate that the audio has been turned on at the transmitter, and that the audio output on the
receiver is enabled. When the “P” is on, the audio is enabled. If the “P” is flashing the pilot tone is not detected and the
audio will be muted (squelched). In the other compatibility modes, no pilot tone is used and the “P” is never displayed.
Audio is present whenever the receiver detects a sufficiently strong signal.
Activating the “pilot bypass” function in any mode causes a lowercase “b” to appear in the pilot indicator position on the
main window and forcibly unsquelches the audio.
Poor.signal-to-noise.ratio.
Associated transmitter gain set too low.
The noise may not be in the wireless system. Turn the transmitter
audio gain all the way down and see if the noise remains. If the noise
remains, then turn the power off at the transmitter and see if it
remains. If the noise is still present, then the problem is not in the
transmitter.
If noise is still present when the transmitter is turned off, try lowering
the audio output level on the associated Receiver Module and see if
the noise lowers correspondingly. If the noise remains, the problem is
not in the VR Field System.
Receiver Module output is too low for the input of the device it is
feeding. Try increasing the output level of the associated Receiver
Module and lowering the input gain on the device the Receiver Module
channel is feeding.
Distortion.
Input gain on associated transmitter set too high. Check and/or
readjust input gain on transmitter according to the manufacturer’s
recommendations and then verify the setting with the audio meter in
the associated Receiver Detail Screen.
Audio output level too high for the device the Receiver Module’s output
channel is feeding. Lower the output level of the associated Receiver
Module.
