  1. Hi guys my Mums monitors has stopped showing the video of people at the front door on the monitor. Also the light at the door bell is not illuminating. The sound of the door bell is still working but only showing a blue screen.
    How can I fix this for them. Is it a battery issue?
    Are you able to email me the manual or direction on how to fix the issue. The installer didn't leave any booklets behind.
    Looks like Mum has the M741MB,with black screen pictured above on this site.

    1. Hello, it may well be the power supply.
      You would need to take the monitor off
      the wall, just slide it in the upwards
      direction and it should come off the wall.
      Now check to see if you have a goo 15 to 18Volts
      of DC power to the monitor. If you do the camera
      may have gone faulty in the door station. You can download
      the user manual from the website.

  2. Hi our Haakili screen will only ring very lightly the volume control barely makes any difference

    1. Hi Andrew,
      You may have a poor connection.
      Test the resistance across the volume
      circuit and you may need to ensure
      that it has not gone open circuit.

  3. Hi, I have issuse with my M741MB with blue screen. When press the door bell button, the monitor light up and can hear the ringtone. However the monitor screen always blue, can't see anything, it's the same as when press the view button on monitor, shows blue screen as well. I connect the door bell and monitor with short cable directly, it is the same. Do you know what problems it is?

    1. Hi Li, Blue screen would indicate
      that the video feed is not streaming
      from the door station to the monitor
      station. As you have tried a short
      lead this would eliminate the cabling
      being the issue. So my thought is that
      either the door station and or the monitor
      station have gone faulty.

    1. Hello Jane, so are you saying it continues
      to beep and does not stop. Or is it that it
      beep on odd occasions? One thing to check is
      the door bell button, ensure that it has not
      had anything, spilt on it, and the button is
      maybe getting stuck in?

  4. Door bell outside rings when pressed however cannot hear it ring indoor but can see the camera. Any help to why it isn’t ringing inside. It used to ring?

    1. Hello, the only thing that comes to mind
      is that the audio wire from the door station
      has gone open circuit. There are four wires
      that run from the door station to the monitor
      station. Two are the power, one is video and the
      other is audio. Check that all four wires are
      connected and are not open circuit or broken!

  5. Hi my haakili La707M recently stopped working after it turning itself on and off somehow. But since i cannot ring door bell or see anything on monitor display. Any help.

    1. Hello Seb, thanks for your question, normally when an
      electronic device is powered off and back on again,
      but the device does not power up, the issue is with
      the power source. The intercom system is powered via
      a white plug that is plugged into the back of the monitor
      station. You could check to ensure you have voltage at
      this point with a multimeter. If you are not comfortable
      doing this I would replace the power supply without testing!

  6. Hi team, we recently have had our m741 monitor go dead. No power lights or response, thinking it occurred after a power outage. Power from the 240 is good. Is there an internal fuse or similar in the monitor that may have blown and can it be replaced? Thanks

  7. oops

  22. Hi we have a Haakili M-741mb and we would like to know how to turn up the volume. It was quite loud but now we can hardly hear it. I have searched your site and I am unable to find any information but it clearly states in the features that this can be done.

    1. At the bottom of the M741 monitor there are rotary switchers. As per the user manual number 13 is the volume control.

      By rotating this switch you can increase or decrease the speaker volume.

  23. Your user manual for the M741M is absolutely a waste of time. No real detail about how to use features - if any.

    1. Hi Frank,

      We appreciate all opinions and views, good or bad.

      We are here to help all our customers.

  24. This is a comment to the admin. Your website is missing out on at least 300 visitors per day. I have found a company which offers to dramatically increase your traffic to your site: nsru They offer 1,000 free visitors during their free trial period and I managed to get over 30,000 visitors per month using their services, you could also get lot more targeted traffic than you have now. Hope this helps 🙂 Take care.
