PROGRAMMING 

You may find it helpful to read through the programming instructions before getting started. This will better familiarize 
you with the operation of the UniTech, and will make the actual programming go much quicker. Be aware of the 
following notes. 

If you wish to return to normal operating mode at any point during programming, hold down the ENTER button for 3 
seconds to exit the programming mode. 

While programming, if no buttons are pressed for approximately 2 minutes, UniTech will automatically return to 
normal operating mode. 

Programming changes can be made while UniTech is operating — changes will take effect immediately. This 
allows you to make minor adjustments “on-the-fly” and fine tune the performance of your system. 

When you’re ready to get started, hold down the ENTER button for about 3 seconds to go into the programming 
mode. Release the button when you see the following display...
