How to fix if the remote control does not work on your 3M MP7750 projector?
Sometimes, the replacement remote control may not work on your projector when you use it for the first time. In this case, we have to find out the reason that makes it not function.
Test the remote control
First, let’s test or check if the replacement remote control was broken when it was on the international shipping way.
To test the remote control, open your phone camera ( If your camera is iPhone, please ensure to test on the front camera which is located on the iPhone screen side) and point it at the projector remote control signal Infra-Red light on the top of the remote. And then, press any key of the remote to check if you could see the Infra-Red light flashed on the phone screen.
If you could not see the Infra-Red light, please check the batteries plus and minus terminals. And please contact us if you confirm the batteries were installed correctly.
Use the remote control near the projector’s remote sensor
Secondly, the remote control works with the projector’s remote sensor. After testing the remote control Infra-Red light work, confirm that you are using the remote. Generally, most of the projector’s remote sensor is located in front side of the projector.
The sensor senses the signal within 60 degrees range (30 degrees to the left and right of the sensor) and 3 meters about.
Therefore, you have to ensure to use the projector remote control within the sensing area.
Changing the remote control signal frequency
In most of the projector remote controls, they have two choices of signal frequency mode.
For the 3M projector remote control, it provides two different signal frequency mode: the factory-set initial mode 1 (Normal) and mode 2 (High).
The switching function is to prevent remote control interference when operating several projectors or other videos devices at the same time.
Furthermore, when you change the frequency of the remote control signal, please remember to set the same mode in your projector’s REMOTE FREQ. For further information on how to do this, you need to read your projector manual on chapter Remote Control Code.
