3.2. Hour Format Setting
We can click the button to select the hour format. For 12 hour format, there will be a dot on the left upper corner to show that it is PM, if no dot, it is AM.

3.3. How to Reset
We can click the button to select RES. When the display screen shows RES, we should stop clicking, then the clock will restart. In this way, the clock is reset to factory default settings.

Operation Status

Once powered up, the clock will go through:

Self- check
IP Address
Time Display

4.1. Self-check

Self-check status aims to inspect whether all LED segments are in a good condition. This status lasts 10 seconds, from displaying 99:99, 88:88…to 00:00.

4.2. Assigning an IP Address
There are two options for configuring an IP address to each GlobalTime clock:

DHCP (Factory Default Settings)
Assigned Static IP v4 Address

By default, when powered up, the clock shows “DHCP” first and then the IP address. If no DHCP server available, then please refer to above 3.1 to use a static IP.

4.3. Time Display

At first, the time is displayed as 00:00+ time zone. If it is not synchronizing with the external time source, it will keep running based on this time zone. Once the clock can synchronize with the network time sever, it will display the correct time.

(4) By default, the clock is configured to use DHCP. If we want to use static IP for the first time, we must long-press the red button on the backside to select SIP. The default IP is 192.168.2.55. Whatever we use, we must ensure that our PC and the clock are in the
same network, then we can see the clock on the software.

5.1. IP Search
The management software supports both Broadcast (255.255.255.255) and Unicast ways to search out online client clocks. Broadcast is the factory default.

Broadcast
Select “Broadcast”, and click “Search”, the software will automatically search online clocks in the subnet, and group IPs based on different subnets.
Unicast
Select “Unicast”, and input the initial IP you want in the bar, then click “Search”, the software will search from the initial IP to the last one. For example, to search all clocks in subnet 192.168.3.0, you can input 192.168.3.001, and then search one by one till 192.168.3.254.

Troubleshooting

Check the host IP configuration and verify that the network can communicate with the time server preset.

7.2. Some LED Segments are Dark.
Reboot the clock to check if there are dark segments under the self-check process. If yes, the display screen needs to be replaced.

7.3. The Management Software Fails to Search out the Clock.
Make sure that the user’s computer and the clock are in the same subnetwork and the firewall is set correctly.

7.4. The Clock Fails to Synchronize with Any Public Time Server.
The user should make sure that his network can visit the internet time source, and the time server is running its NTP service successfully.

7.5. The Small light at the Bottom Right Corner is on All the Time.
This condition indicates that the clock can not synchronize with the time server preset. Please check the
