After intalling m-audio when i am trying to use vocal mic, its not operating. signal are getting transmitted to the card(green led blinks while making sound on mic). computer software installation is ok.

The static tells me that your audio chip is working, but the stages ahead of that are not feeding a signal to the audio amplifier. The intermittent receive sounds like a bad antenna connection, or bad contacts on your transmit - receive circuits. I don't know the Cobra 29 LXBT circuitry, but likely a relay is switching between transmit and receive when you press the mic key. You could try connecting your antenna to the pins on the relay that carry the rf signal to the receiver circuitry. If you suddenly starting picking up signals, you know the switch is the problem, as you have by passed the switch momentarily. Don't try to transmit in this condition.

14.2.2 To Make a Diagnosis:
1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.

When you have the error code you will be able to diagnose the fault.

• Once abnormality has occurred during operation, the unit
will stop its operation, and Timer LEDs blink.
• Although Timer LED goes off when power supply is turned
off, if the unit is operated under a breakdown condition, the
LED will light up again.
• In operation after breakdown repair, the Timer LED will no
more blink. The last error code (abnormality) will be stored in
IC memory.
• To make a diagnosis:
1. Timer LED start to blink and the unit automatically
stops the operation.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled by
pressing the CHECK button continuously for 5 sec-
onds or without any operation the remote control for
30 seconds.
8. The LED will be off if the unit is turned off or the
RESET button on the main unit is pressed.

When you have the error code, we can work out what to do next.

• To make a diagnosis
1. Timer LED start to blink and the unit automatically stops the operation.
2. Press the CHECK button on the remote controller continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display. Note: Display only for "- -". (No transmitting signal, no receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote controller. The code "H00" (no abnormality) will be displayed and signal will be transmitted to the main unit.

If no codes are matched, power LED will light up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled by pressing the CHECK button continuously for 5 seconds or without any operation the remote control for 30 seconds.
8. The LED will be off if the unit is turned off or the
RESET button on the main unit is pressed.

When you have the error code, you can narrow down the problem.

Hi Tania,
Have you gone through this checking sequence.? it's from a Panasonic a/c manual. It could be something as simple as a clogged filter. Once you have rectified the fault, you will probably have to clear the fault code as described at bottom below, before it will condescend to work again.

You've obviously checked battery strength, battery connection and volume settings for the dead mic...does the green transmit (RF) LED light when you turn the mic on? Does the red audio (AF) LED light when you talk into the mic? Best solution....buy a better quality wireless system ($85 wireless?!? ...no thanks).

Make sure the switch is set to "mic/line" and not "guitar"
Your input level will be set by the "input L" or "input R" knob, depending on which side you are using. Start with them all the way down and then sing into the mic, turning them up until you get a signal about halfway up the bar in Cubase. That should give you plenty of headroom for clean vocals.
It may be difficult to get a good sound if you have one of those cheap mics that has a "1/4" jack instead of a 3-pin XLR jack. You might want to go to your local music/pro audio store and invest in a "condenser" microphone, which is good for vocals in the studio.

What are your microphone settings in the BIOS (Basic Input Output System) in the pre-boot setup?

LED Display gives you your display visual alerts, signal strength, and operation mode. Here is an attached link for the manual.....http://www.uniden.com/pdf/LRD6399SWSom.pdf
But to answer your question here is what the difference between the green light and the red light are:
1. X-Band Signal Indicator—A green LED lights and blinks to
indicate the presence of an X-band radar signal. The blink rate
increases as the radar source gets closer. A distinct audio alert is
also heard.
2. K-Band Indicator— An amber (orange) LED lights and blinks to
indicate the presence of a K-band radar. The blink rate increases as
the radar source gets closer. A distinct audio alert is also heard.
3. Ka-SuperWideband Signal Indicator— A yellow LED lights and
blinks to indicate the presence of a Ka-SuperWideband radar
signal. The blink rate increases as the radar source gets closer. A
distinct audio alert is also heard.
4. Laser Signal Indicator— A red LED under L lights and blinks to
indicate the presence of a laser signal. A distinct audio alert is also
heard.
5. SWS Signal Indicator— When an early warning hazard or
informational signal is detected, the yellow SWS LED begins to
blink and the amber K-band LED lights. A distinct audio alert is
also heard.
6. Power-On Indicator— A green LED under P lights to indicate
power is being supplied to the unit and the unit is turned on.
7. LED Signal Strength Meter—Four LEDs give an accurate visual
indication of the strength of radar or laser signals.
8. City Mode Indicator—A green LED under C lights to indicate
that you selected City Mode.
9. Auto Mute Indicator— A red LED under M lights to indicate that
you selected the Auto Mute feature.

Please make sure you give me a rating and I hope this helps,

Im having the same probz, got a Hp Pavilion Vista using mobile pre amp usb when i record using a condenser mic XLR nothing is picked up from the channels in Cubase or Nuendo. Im trying to record vocals but the Mic is not picked up and i cannot hear myself in the headphones and it wont transfere to cubase.

It has worked before when i had a desktop, but this only worked with a separate m-audio sound card inside the desktop and i plug in the output jax leads from the desktop (soundcard) to the m-audio usb pre amp

Is this why it is not working for the laptop do i need a Jax connection and where is this audacity
