VTech Safe and Sound DM111-2 Troubleshooting
Device not turning on
No matter what you do, you can't get your parent or baby units to turn on.
If either one of your parent units won’t turn on, you may simply have drained or faulty batteries. Plug in the power cable to the parent unit to check if the device will turn on. If your device will only turn on when plugged into the power cable, then you may have to replace the batteries in your device. The VTech Safe and Sound DM111-2 Battery Replacement guide explains how to remove the batteries. If your baby unit remains unresponsive after changing the battery, read on.
Faulty power cable
If your baby unit will not turn on when plugged into the power cable then you likely have a faulty power cable.
Static and noise
Your baby monitor is producing white noise or making strange sounds.
Parent device and receivers are too close
If either of the parent devices are too close to the baby monitor, sounds will begin to loop between the transmitter and receiver causing a screeching noise. to correct this move either the speakers or the receiver farther apart.
If the device is on and there is either unclear sound or no sound at all, you may have a faulty or dead speaker. In order repair or inspect the speaker you will need to open the device, which is described in the VTech Safe and Sound DM111-2 Speaker Replacement guide.
If you are experiencing static or other extra noise then you may be having trouble with your antenna. in order to check the antenna you will need to open the baby monitor which, is shown in the VTech Safe and Sound DM111-2 Antenna Replacement guide. the antenna is a slender metal piece near the top of the monitor. check to see if the wires connecting the antenna to the motherboard are intact and that the antenna itself is not broken or damaged. if you see damaged or detached wires then continue to the steps pointed out in the VTech Safe and Sound DM111-2 Antenna Replacement guide.
Not responding to button inputs
No matter how hard you press the buttons, the device will not respond to button inputs.
Check to see if the rubber buttons are placed correctly on the motherboard of the device. Open the device to locate the rubber buttons and try aligning them with the holes in the face of the device as well as the buttons on the motherboard.
If the buttons do not seem to be responding, you must first evaluate if the device is powering on. If the device is not powering on then you must troubleshoot that first. The next step would be to open the device and locate the button. Check to see if the buttons are replaceable or not. If not then you must replace the whole board.
LED lights not working
The power, low battery, and/or volume lights on will not turn on.
Check if your batteries are functional. Try replacing batteries to see if the LED’s are lighting up.
If LED’s are not working, and the device has fully charged batteries and or is connected to an wall outlet, the issue with the mother board. You must replace the motherboard.
Device is beeping
As long as the device is within range and nothing such as large metallic objects are in the way, connection issues, antenna issues, or even motherboard issues maybe at hand.
As stated before under powered devices can do strange things, that annoying beep may be once again as simple a fix as a fresh pair of batteries.
Power supply replacement/repair
If you have checked the batteries and the Beeping persists. It may still be under powered due to either the batteries seating having a bad connection to the motherboard, or the power supply jack that connects to an outlet may have become loose or broken in this case as well. If upon inspection any suspicions are raised as to this being the issue one should refer to the Power Supply Replacement and Repair guides to remedy the issue.
If you’re still having a persistent beep and power issues have been ruled out, perhaps the antenna is the culprit. Check to see if the wires connecting the antenna to the motherboard are intact and that the antenna itself is not broken or damaged. If you see damaged or detached wires and or antenna, then continue to the steps pointed out in the VTech Safe and Sound DM111-2 Antenna Replacement guide.
If the batteries and the power supply connections are fine, the antenna appears in good shape and the beeping persists, the final step would be a motherboard replacement. The radio components within the monitor which are a part of the motherboard may be having issues. Unfortunately once again these components would be very difficult to service therefore one should refer to the VTech Safe and Sound DM111-2 Parent Unit Motherboard Replacement guide in order to go about swapping out the motherboard and addressing the beeping issue for the parent unit. In order to diagnose the baby unit. If replacing the parent units did not stop the noises and you notice symptoms such as powering on and off or refusal to turn on or record then the problem may be with the baby unit. to replace the motherboard in the baby unit refer to the VTech Safe and Sound DM111-2 Baby Unit Motherboard replacement Guide guide
