On the back of the unit there is a Command Mode switch. Set one unit to 1. The second unit to 2. And set the CX995V to 3 , if it has a switch ( or keep the number and set the CX875P's to different numbers). You can also power on the CX875P by pressing Play. If you have a Sony audio equipment you might need to adjust again.
You might need to learn the alternate commands from the original remote. The switch is under the left AA battery on the CX875P remote .
If the codes aren't listed, could you post your codes in the file area ? I might need to change my set-up soon.
