ATX Installation and User’s Guide

Q.How do I synchronize my AirTime wall clocks?

A.Press the TRANS button on the ATX. You will see T – TR – TRN – TRNS flash on the display. At the wall clock, press the Reset button. If the wall clock does not correct within several minutes, then it may be out of the 150 foot range of the ATX. Relocate the wall clock closer to the ATX.

Q.Can I use more than one ATX?

A.Yes. Secondary ATX units can be set to Repeater mode to increase coverage. All repeater ATX’s within the 150 foot range from the first ATX will re-broadcast the signal. As long as ATX Repeaters are within 150 foot range of each other there is virtually no limit to how many ATX’s you can install.
