Installation & Operation Manual
clock is powered up. If done successfully, three “8's” will scroll across the display before entering the usual start up
routine.
6 Troubleshooting
6.1 Flashing Seconds
There are two instances when the seconds (6 digit clock) and the AM/PM dots will flash to indicate a problem.
6.1.1 Lost Network
If the seconds and the AM/PM dots are flashing with a 50% duty cycle (0.5 seconds ON, 0.5 seconds OFF) the
network was lost, check to make sure everything is connected properly on the network and verify NTP server
activity by connecting the clock via ethernet, rebooting, and getting a time displayed.
6.1.2 Lost Access Point
If the access point or router was lost the seconds will flash with a 25% duty cycle (0.25 seconds ON,
0.75 seconds OFF). This also scrolls "AP lost" when the access point is lost and "no AP" every 10 seconds
while it is attempting to restore connection. Try rebooting the access point.
6.2 AM/PM LED Indications
During initial boot up when in WiFi mode (no ethernet connection), the AM/PM LED's will indicate the state
that the clock is in throughout the initialization process.
6.2.1 Both AM & PM Off
When both the AM and PM LED's are off, the WiFi module is in the initialization state.
6.2.2 AM On, PM Off
This sequence indicates that the WiFi module is initialized and the clock is attempting to scan and join a
wireless network.
6.2.3 AM Off, PM On
This sequence indicates that the clock has successfully joined a wireless access point and, if in DHCP mode, is
attempting to acquire an IP address.
6.2.4 Both AM & PM On
This sequence will only be present if the clock is operating in DHCP mode. If in DHCP mode, this
combination means that the clock has received an IP address from the DHCP server. If the clock is
using a static IP address, this pattern will not be displayed and the “AM Off, PM On” pattern will
remain shown until the clock receives a time update from the NTP server. At which point the AM/PM
LED's will display the correct pattern corresponding to the current time.
