Checking Tire Pressures and Temperatures:
The TireMinder® TM-A1A™ TPMS will constantly monitor all tires which have been programmed. If you wish to
check each tire pressure and temperature, press either a RIGHT button OR LEFT button while in the “M” mode.
The tire position will be displayed along with its exact pressure. Press again and that tire’s temperature appears.
Press again to scroll to the next tire. If a tire position shows “no5 (S)”, it tells you that communication has been
lost between that transmitter and the monitor. This needs to be addressed ASAP (See pages 38 & 39).
System Expansion (adding a towed vehicle at a later date)
So, you’ve had the A1A™ installed for two trips and love it. Now you want to add four more transmitters for your
towed vehicle.
Method A: Install the new transmitters following the directions at the very beginning of this book (Learn
mode “L” and Pressure Setting mode “P”). Follow these instructions and you’ll have the new
transmitters installed in no time.
Method B: Delete all the original tire positions and start over (See Full Delete see pages 31 & 32).
Method C: Call a Minder TPMS specialist who will be happy to “walk you through it”.
This would be a good time to remove all transmitters and check the batteries (3.0 v or higher), check the O-rings
and the black protective caps for damage.
