Password
(000 ~ 999)
For security purposes, you may set a unique password for your
ATX6. To change the Password, use the INC, NXT and SET
buttons. The INC button will increment the digit over the
displayed cursor. The NXT button will move the cursor to the
next digit. The SET button will enter your final selection. If you
do not wish to change the current Password, simply press SET.
This is the final step, indicated by the display showing the
correct time and Day-Of-Week cursor. Daylight Savings Time is
also indicated.

Operating Modes:
Normal:
In Normal Mode, the ATX6 will listen for synchronization signals
from the device selected as the Time Reference (Set-Up
parameter # 7). If an external Time Source is selected, the ATX6
will synchronize its Real-Time-Clock to that source, when the
synchronization signal is received. In the event of a power
failure, the RTC Date and Time parameters are protected and
continue to operate using a Lithium "coin-cell" battery.
In Normal Mode, the ATX6 transmits a radio signal (indicated by
the UHF LED flashing once) to other ATX-series devices during
the last ten seconds of each minute, If RC Emulation is enabled
(Set-Up parameter # 15), the ATX6 will transmit a radio signal to
RC-series Wall Clocks at the top of each odd minute; except the
minute designated to generate a relay closure (see below). If an
external amplifier is used, the ATX6 will transmit a signal every
15 minutes of each hour.
If "Dry Contact" (Relay) synchronization is not selected as the
time reference (Set-Up parameter #7 is not equal to 'Syn'), then
the ATX6 will activate the local Relay [and Wireless Remote
Relay (option)] at the selected HH:MM:00.
If 485 is not selected as the time reference (Set-Up parameter #7
is not equal to '485'), then the ATX6 will transmit the RS-485
protocol to synchronize Lathem Master Clocks and Bell Ringers
that support the RS-485 interface at the 40
minute (HH:MM:40). This is indicated by the 485 flashing
indicator once.
Each day for 15 minutes, beginning at 1:05AM, 3:05AM and
10:45PM the ATX6 will listen to and re-evaluate its radio
environment, to determine if any Automatic Time Slot
adjustment is required. During this period, the "~" symbol will
flash and radio transmissions are inhibited. Transmission
parameters are automatically adjusted, as may be necessary. If
another AirTime Transceiver (ATX or ATX6) is selected as the
time reference for this unit (Set-Up parameter #7 is set to 'Air'),
then this ATX6 will synchronize its clock to the received
transmission. The ATX6 will indicate when it receives a signal by
the UHF LED flashing twice.
