How to change channels on your interpreting equipment: Retekess & Similar devices Interpreter Ray Oh

How to change channels and volume levels on Retekess and similar interpreting/translation equipment. Interpreter Ray Oh.
I forgot to mention: for the receiver, you have to let go of the power button after the device turns on. If it does not work, just turn off the device and try again.
There are subtitle (Closed Caption) option for the hearing impaired, and it's available in multiple languages. Feel free to add additional language captions!

How is the longevity of this receiver? Along with that, would you say it works well in long distance?
