Radio is Cobra 29 LTD classic antenna light stays red when i go to calibrate it


all right,when the radio is unkeyed is the light green or red? So now I ask another question,are there two red lights or one that come on?If there is only one then don't worry about it .Its supposed to come on and turn red when you key,Its the other red light that tells you that you have a problem.If its on then check your SWR with the meter on the radio and get it down lower than 2.5:1 and then you should be set to go.

Does the green light come on after freezer is turned back on?


if you turn the freezer off for some time then on again the red light has to come on as an indicator for high temperature it goes off by itself when the freezer attains the required temperature according to the thermostat settings ,that is the lower the settings the faster the red light goes off. the orange light indicates super cooling and the green light indicates power supply.if you turn the two lights off and the freezer still works without the green light on that means that the bulb for the green light is faulty and you don,t need to worry

When i key in both green lights turn red. is this normal ?


One of the lights is marked RX/TX. This light normally turns red when you press the mike key. The other light indicates a bad SWR if internal circuits are properly aligned. If someone has turned the pot which sets the level at which the light comes on, it may come on when you press the mike key. Check your SWR with an external meter to see if you have problems in the antenna system. The way I set this light in my shop is to put a 150 ohm resistor on the antenna connector and set the control so that the ANT light just comes on.

I need the code for sharp tv please


Configuring codes:
  1. Turn on the component that you want to set up. In the code listing find the 4-digit code numbers for your component brand.
  2. Hold the component key down until the green indicator light comes on. The green light should come on after approximately 3 seconds.
  3. Release the component key.
  4. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
  5. Within thirty seconds, enter in a 4-digit code number. The component key lights will blink with an upward motion when a code has been successfully entered. In this case proceed to step #5. If the code has not been successfully entered, the componment lights will not blink. In this case return to strep #1 and start over.
  6. Test code by pressing "Power" key. If the component turns off, you've got the right code. Follow the same instructions to set up your other components. If the component doesn't turn off, return to step 2 and use the next 4-digit code listed. Note: If none of the codes turn your component off, try the Auto Code Scan function.

Auto Code Scan:
    The Auto Code Scan feature allows you to set up your components without having to enter in code numbers. The Jensen will do the work for you! (It may take a few minutes to find your code using this method.)
  1. Turn on the component that you want to set up.
  2. Hold the component key down until the light comes on. The green light should come on after approximately 3 seconds.
  3. Release the component key.
  4. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
  5. Press "0" - "9" The green light will blink as codes are sent.
  6. As soon as the remote turns your component off, press the "action" key. (You have 1 second in which to press the "action" key to save the code.) The component key lights will blink with an upward motion when a code has been successfully entered. The component is now programmed. To find that code, proceed to Code Readback.
  7. If none of the codes turn your component off, return to step 2 and start over.

Code Readback:
  1. Hold the component key down until the green indicator light comes on. The green light should come on after approximately 3 seconds.
  2. Release the component key.
  3. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
  4. Press the "enter" key.
  5. Count the number of times the green light blinks. There will be four numbers, separated by a two second pause. The red light will tum off after the remote is finished reading numbers back. Make sure you write the code number below for future use!

Multi-Component Power On/Off:
    The Jensen remote has the ability to turn On/Off multiple components at once. When you perform the following steps, you can turn On/Off the TV, VCR, Satellite, Cable Box and Audio Receiver.
  1. Press the "action" key.
  2. Press the "power" key. Note: This feature does not work for DVD and CD.

Volume Priority Punch-Through:
    When you press the volume keys on the remote they will control the volume on your TV. If you have a home theater system and want the volume keys to control your receiver only, you may set your volume priority to the receiver.
  1. Hold the "RCVR" key down until the green indicator light comes on. The green light should come on after about 3 seconds.
  2. Press "RCVR" key.
  3. Press "Vol+" key. To disable the volume priority you have to set and return to the default.
    To change back to TV priority:
  1. Hold the "RCVR" key down until the green indicator light comes on. The green light should come on after about 3 seconds.
  2. Press "RCVR" key.
  3. Press "Vol-" key. The volume priority will now default to the TV volume.
hope this helps
