!! IMPORTANT !!
This AirTime System is designed to provide highly accurate and
reliable time reference in your building. You must follow these
instructions or your clocks will fail to operate properly. You must
allow the transmitter to sit overnight and receive the WWVB signal
before installing your wall clocks.
FOLLOW THESE INSTRUCTIONS BEFORE INSTALLING THE WALL CLOCKS
1. Remove the back cover of ATX and slide the Mode Selection switch
to the Master position.
2. Insert two (2) CR123A lithium batteries (provided) and replace the
back cover or connect the optional 6VDC adapter. Note: You can
not use both the batteries and the AC adapter at the same time.
(If the ATX looses power, replace the batteries or check the
optional AC adapter and reset the clock starting at step 1 above)

Q. When does the ATX listen for the WWVB radio signal?
A. The ATX listens for the WWVB radio signal 2 minutes and 40 seconds
after every hour. The strength of the last signal reception can be
determined by the signal strength indicator (
) on the display.
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.
Q. If I manually set the Daylight Savings settings will the WWVB signal
affect the ATX?
A. No, the manual Daylight Savings settings override the automatic
WWVB signal for Daylight Savings.
Q. Why is the ATX changing for Daylight Savings in the wrong month or
week?
A. If you have manually set the Daylight Savings month and week they
may be incorrect. Verify your settings by following the instructions
on page 6.
