Processing seems a bit cheap - thanks to the installation instructions done easily and quickly.
If you have a voltmeter and a little interest in technology, one can derive the power to the receiver module (12-24V AC or DC) of the motor mounting plate of the drive and requires no external power supply. Since the receiver consisted of platinum components and has no closed housing, I decided for installation in the motor drive housing. Receiver module is small and it can be glued to a vacancy.
Then things got interesting - after critical reading some customer reviews I came for programming.
First of all I did not need a hotline, only 2 hrs. Time. The difficult in my opinion is the receiver and the transmitter to make to communicate.
Power to the receiver module, battery input to the keyboard, initialization code and desired ...... no function. Various attempts lt programming attempts -. Without success. Read the instructions, you will be none the wiser.
Another attempt at the receiver module are 2 instructions for installation and operation - thought the manual is specifically for Schellenberg drives.
Since the receiver module a small button next to the LED, 1x is pressed, code is entered on the transmitter and key button again entered code on the transmitter and key button, then I can not say whether I again pressed the little button on the receiver or not, anyway, the gate opened. JOY
Remaining programming steps or code changes were no longer a problem - function exactly as directed.
As I said, my transmission is 10 meters and now works correctly.
Other reviews as battery change, etc., indeed seems to be a bit awkward. If you build it all together, you know afterwards pointed again is to disassemble.
Hope to have served so few.
