Max Number Of Remotes for 5706v?

So I have a Viper 5706v I installed myself a few years ago and everything works perfectly. I have one two-way remote (7756v) and one one-way remote (7656v) that came with the the system. How many remotes can the system support at one time? I'd like to pair another 7656v, for a total of three remotes, but couldn't find anything about the max number that could be paired. FWIW, I want to add another remote because I have my one-way wired to an Alexa controllable relay module. Rather than get my remote and push the button, I can start my car by voice command which is pretty cool.

4. after the 4th one it will start erasing the other remotes33 years as a installer now just a retired old guy. Favorite thing to install/topic are remote starts/car alarms. Stop using test lights!!!

mgoetz74, thanks for the reply. I figured it worked something like that. Four is a decent number, I thought it might only support two.
