Installation IntroductionSpecifications
Wi-Fi is a popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio
waves. Wi-Fi and Simple Network Time Protocol (SNTP) are used to make installation and setup as simple as possible. All you
need to do is power your precongured clock in an area where the intended wireless local area network (WLAN) signal strength
is sufficient.
Each Wi-Fi clock is factory-congured to receive the precise time signal from your network time server. They also automatically
correct for the Daylight Saving Time changes and require no maintenance for up to 5+ years. These Wi-Fi clocks only require
synchronization twice per day using SNTP and create very little network traffic.
Network
These precongured Wi-Fi Clocks are plug and play on networks with Dynamic Hosting Conguration Protocol (DHCP). A limited
access point mode is also available for clocks that are not precongured at American Time as recommended.

Installation IntroductionSpecifications
Before installing verify:
• Dynamic Host Conguration Protocol (DHCP) settings
• Firewall port 123 is open for UDP data
• Good Wi-Fi coverage at intended installation location.
• Green gear locking pin (A) is removed from the movement
1. Adjustments/Conguration via limited access Point mode
If clock was precongured at American Time as recommended, skip to step 2.
Otherwise, refer to Button Operation and Conguration (Limited Access Point mode) sections to congure clock manually.
2. Apply power to the clock by inserting the barrel plug (C) of the battery pack into the left side of the Wi-Fi module where the
power connection is located.
nNote: If green gear locking pin (A) has not been removed, remove it prior to applying power.
i. Verify the LED (B):
1. Flashes red when power is applied to the clock.
2. Flashes green within 60 seconds.
3. Green ash stops within 120 seconds.
ii. Verify the clocks hands begin to spin rapidly within 6 minutes after applying power.
iii. Verify the correct time on the clock within 20 minutes of applying power.
3. Place the clock on the wall using the hanger on the back of the clock or the optional security bracket (sold separately).

A recessed push button is located in the lower central part of the Wi-Fi module. It can be used to initiate 4 different operations:
1. Conguration (via Limited Access Point) .
2. Clock homing (sending clock hands to 12 O’clock).
3. Firmware updates (internet access is required).
4. Factory defaults restore (restores to the conguration that the clock was shipped).
Each operation is proceeded by a number of orange ashes. If the button is released after the operational ash count (see list
below) it will attempt the specic operation listed.

Installation IntroductionSpecifications
The clock will act as a limited access point for direct Wi-Fi communication to complete conguration. After connecting to the
clock with a wireless device it can be congured with a web browser.
nNote: If your clock was precongured by American Time this process is unneeded unless changes are required.
To enter conguration (limited access point mode) complete the following process:
Apply power to Wi-Fi module by inserting the barrel plug (C) of the battery pack into the left side of the Wi-Fi module where the
power connection is located.
nNote: If green gear locking pin (A) has not been removed, remove it prior to applying power.
1. Verify the LED (B) starts ashing red.
2. Press and hold the button located on the middle of the Wi-Fi module.
a. The LED (B) should turn solid green to indicated the button press (continue holding the button).
b. Wait for the LED (B) to ash orange one time. This will take about 2 seconds (additional ashes indicate other modes).
3. Release the button.
a. Verify the LED (B) turns solid red indicating Limited Access Point mode is active.
4. Connect to the clock with a Wi-Fi enabled device (SSID will show up as AT_Prov_xxxxxx under available wireless
networks, where xxxxxx is the last 6 digits of the mac address.
5. Enter 192.168.240.1 into the URL of a web browser of the Wi-Fi enabled device.
6. Refer to Clock Conguration (page 9) to congure clock settings and Wi-Fi Conguration (page 10) to congure Wi-Fi
settings.
7. When adjustments/conguration are complete, the LED (B) should begin ashing again.
8. Disconnect power from the Wi-Fi module by disconnecting the barrel plug (C) of the battery pack from the left side of the
Wi-Fi module where the power connection is located.
nNote: Power should be applied at the intended installation location to verify good Wi-Fi coverage.
