User Manual of MH107 door & vibration
sensor
Installation and Use.
1. Remove the insulating tab, and you will hear one "beep", which means the battery is
connected.
2. Tear off the protection paper of the adhesive tape on the back of MH107, and stick the
magnet part parallel to the alarm, ensuring the gap to be less than 1cm.
Note: Default password is "1223" If you change the password use that instead.
If the door/vibration sensor was bought as part of a kit it would have been set up for
you, but if it was bought separately then you will need to do the following step.
Reset to default factory setting.
Open the battery cover and take out the battery. After 3 seconds, press and
hold the learn button, and insert the battery. When you hear three beeps,
it has been reset to default factory settings, release the button.
