Nick,
This is a bit "off", but, maybe similar.
We have a PW Lexor on which we've installed AirLift airbags with a wireless controller. Airlift is a competitor to Firestone RideRite.
I've found that the wireless controller eats batteries. Ours has two AA batteries, and "new" batteries last less than a full season. I don't change the pressures frequently, but I think the wireless controller regularly checks the bag pressures to see if anything needs doing.
In our case, though I still have the wireless controller manual, I can also get it from the manufacturer (AirLift) website. Maybe you can do the same with Firestone.
Our installation is "independent" - i.e., we can independently control the bag on either side, and I'd suspect yours is similarly built. Thus, out controller allows me to change the pressure in both bags simultaneously, or each bag independently - my choice.
The good news is, once you've figured it out, you'll love 'em.
One more thought. If you're still having trouble, if you'd post the "instructions" you have (yes, that'll take a bit of typing), you may well find that you get a much better explanation of how to use what you have.
Cheers.
