Question about Motorola Talkabout T5720 (7 Channels) 2-Way Radio

1 Answer

Staying keyed up after button release

The unit seems to stay keyed up after pushing the button and then releasing. When powered up, the unit will receive normally, but once it is keyed up and then released, it continues to transmit, but no more voice audio can be heard and the unit is unable to receive until power cycled. The light also stays on after the button is released and the other radio still hears the slight static associated with the faulty radio transmitting but voice can no longer be transmitted after release.

I have never seen this problem before, check if the VOX is activated, this could cause to transmit the radio, but the voice must be transmited. check if the Accesory connector is not dirty, clogged or damaged

I have a 2013 dodge grand varavan and my key fob quit working. I replaced the battery and it worked once and then quit working what could be wrong?


Since you replaced the battery, and it worked once, there seems to be 3 main possibilities. First, the fob itself is not receiving full power from the battery (contact corrosion) or the battery is being drained by the fob by not fully releasing the button. Open and check for this. Use a pen point to manually push the little black (usually) button that the plastic button pushes against. It should click or give some other sign of returning to an 'up' position when released if it's working.
Sometimes with an older fob the mechanical action of the button is worn and off center. A dab of good glue and a bit of cardboard or some other non conductor carefully placed under the button can be kludged to get this fault to disappear.
The second main possibility is that the car's receiver or antenna is faulty, not streaming the signal from the fob to the car's computer ECM or BCM (Engine Control Module or Body Control Module) whichever unit is responsible for triggering the lock/unlock functions.
This is more serious and truthfully the BCM is expensive to replace and check (usually Dealer Only). Try the fob cures first.

I'm getting an error messege on a hp photosmart C7180 all in one 0xc18a0106. please help me. I've tried un and reinstalling the software. New ink cartriges. Nothing works.


Solution 1:
  • Push "OK", "Cancel", "Black" and "Color" all at once while turning the printer off.
  • Turn it back on.
  • One more time: push "OK", "Cancel", "Black" and "Color" all at once while turning the printer off.
  • Turn it back on.

Solution 2: Resetting the product:
  • Without turning off the product, disconnect the USB cable from the rear of the product.
  • Remove the cartridges from the product.
  • Wait for the "Insert Cartridges" message on the control panel.
  • Disconnect the power cord from the back of the product.
  • Wait 60 seconds.
  • Reconnect the power cord. If the product does not automatically turn on, press the Power button.
  • Reinsert the cartridges, and then close any open doors on the product.
  • If you receive a prompt to print a calibration page, do so.
  • Reconnect the USB cable to the rear of the product, and then try printing again.

Solution 3:
  • 1. Get the unit into the "Support Menu" by following these steps: Press and hold the "*" key. Press the "#" key and release both keys. Display should say "Enter Special Key Combo". Press and release in sequence the "1", "2" and "3" buttons. Display should say "Support"
  • 2. Press and release the right arrow button until the display says "System Configuration Menu".
  • 3. Press and release the "OK" button.
  • 4. Display should say "Hardware failure status". If not there already, Arrow Key over to "Hardware failure status",
  • 5. Press and release the "OK" button.
  • 6. Display should say "Hardware failure status: Clear. Press OK to clear".
  • 7. Press and release the "OK" Button. Message changes to "Hardware failure status Cleared. Press Cancel to continue".
  • 8. Press and release the "CANCEL" button as many times as necessary, so that, either the "Welcome to Photosmart Express" screen appears, or, the "Ink System Failure" screen appears. DO NOT TRY TO PRINT AT THIS STAGE.
  • 9. Using the Power Button, turn the unit OFF and unplug the power cable from back of the printer and wall outlet.
  • 10. Wait 30 seconds for the power to get discharged and then plug the power cable into the wall outlet first and then into the back of the printer
  • 11. Turn the unit on. The printer may display message "USE POWER BUTTON TO SHUTDOWN THE PRINTER" followed by "PRESS OK TO CONTINUE". Press OK.
  • 12. If the printer has already initialized, then go to the next step. If not, the printer will start the "ONE TIME INK INITIALIZATION PROCESS". Allow this process to complete and do not interrupt. Once the initialization process is complete, the printer will print out a Diagnostic Page.
  • 13. To verify printer functionality print a SELF TEST PAGE. If SELF TEST prints, then printer is ready for use or Software Installation.
  • 14. If the error is still there, or reoccurs replace the unit.

I recently purchased 6 new 83lm lifmaster remotes when I program them it seems like it makes the others quit working. Is there a limit as to how many you can have programmed at once?


When programming the remotes makes sure you push and release the 'learn' button on the motor unit, then within 30 seconds push the button on the remote control. If you keep the 'learn' button pushed for more than 6 seconds all the transmitter codes will be deleted from the receivers memory.

Need intructions how to program remote control on vip722k second receiver


Press and hold down the SETUP button located on the remote. Wait until the INDICATOR light turns on. It will blink once the button is pushed, however once you see the indicator light stay one, release the button. Click the button to the DEVICE you wish to program. If it is a TV, then click the TV button. If it is the cable box, then click CBL button. After doing so, the indicator should still stay on. Press the DOWN CHANNEL button several times until you see the RECEIVER yo wish to program respond. Example: If it is a TV, then you will notice the CHANNEL change once the remote locates the correct settings for that receiver. If you see the receiver respond and you are pushing the down channel button but nothing is working, it means you passed the internal settings of the remote to the receiver. Try pushing the CHANNEL UP button slowly. It may be able to relocate the the proper settings. Once you see the channel change again, press ENTER to program the remote. If this fails, retry the same steps. In some cases you may miss the correct internal settings.

I have a Denon AVR 1802 and everything seems to be working properly, but I an mot getting any sound from the unit. When I perform a test tone, I get sound from all the speakers, but I can not get sound...


You could try a total reset of the system. To do so, Press Power while simultaneously pressing Speaker A and Speaker B. When the display flashes at about 1 sec intervals, release all buttons. Then select a desired source as normal and see if it plays as expected.

Vista etrex cx will not acquire satellites . It worked okay the last time I used it.It then says poor reception .Use with GPs off. Its a clear day and was yesteday when i tried to use it. There seems no...


My Etrex Legend would not aquire satellites and after several call to tech support, I finally reset the whole unit. First I saved the waypoints on Mapsource. Then with the unit off press and hold the page button (upper right) then push the rocker button in and then push the power button. Once it starts you can then release all the buttons and set the unit outside for about 20 minutes.

Eror oxc18a0106 ink system has failed,unable to copy receive faxes or print


The ink system failure message has a chance to be fixed or it may be a permanent issue. It can be pointing toward a firmware failure in the printer and if that is the case the following steps should fix it.
Press and hold the “*” key. Press the “#” key and release both keys.
Display should say “Enter Special Key Combo”
Press and release in sequence the "1”, “2” and “3” buttons.
Display should say “Support” and display the FW rev (something like R0631R)
Mine reads R0631M
. Press and release the right arrow button until the display says “System Configuration Menu”.
Press and release the “OK” button.
Display should say “Hardware failure status”. If not there already, Arrow Key over to “Hardware failure status”,
Press and release the “OK” button.
Display should say “Hardware failure status: Clear. Press OK to clear”.
Press and release the “OK” Button. Message changes to “Hardware failure status Cleared. Press Cancel to continue”.
Press and release the “CANCEL” button as many times as necessary, so that, either the “Welcome to Photosmart Express” screen appears, or, the “Ink System Failure” screen appears. PLEASE DO NOT TRY TO PRINT AT THIS STAGE.
Using the Power Button, turn the unit OFF and unplug the power cable from back of the printer and wall outlet.
Wait 30 seconds for the power to get discharged and then plug the power cable into the wall outlet first and then into the back of the printer.
Turn the unit on. The printer may display message “USE POWER BUTTON TO SHUTDOWN THE PRINTER” followed by “PRESS OK TO CONTINUE”. Press OK. The Printer will start the “ONE TIME INK INITIALIZATION PROCESS”. Allow this process to complete and do not interrupt. Once the initialization process is complete, the printer will print out a Diagnostic Page. Good Luck!
