The PTC-140 IR (Infrared) Remote has the ability to control up to 4 cameras. Normally, every PTC-140 series camera is set by default to "Camera select 1", so if you have multiple cameras it can become confusing to control a specific camera since they are set on the same preset.
For Example, if we want to program a second camera to "Camera Select 2" we would do the following:
1. Press and release *
2. Press and release #
3. Press and release F2
See the image below for reference
Now, all you need to do is press the camera select button 2 (white button) and you will have control over camera 2. To select camera 1 again just simply press the camera select button 1 (white button).
Note: The remote will communicate with each camera until a new camera selection is made.
