Why does the internal clock go back to 2004 and how can I fix it? (RTR-5W / TR-7W)
The RTR-5W and TR-7W are not designed with a clock backup function. Therefore, when the power is lost due to a power failure, for example, the internal clock will return to the default setting (1/1/2004).
By carrying out [SNTP Settings] in the Network Settings Utility, it is possible to automatically reset the time to the current time.
If you cannot connect to an SNTP server, please set the clock manually.
How to Manually Make Clock Settings
1. Start "RTR-5W for Windows".
2. Right click on the RTR-5W unit for which you wish to make clock settings, and select [Location(RTR-5W) Properties].
3. Click the [Set Clock] button.
4. Make clock settings in the [Set Clock] window.
1. In your web browser, enter the IP address for the TR-7W in which you wish to make clock settings.
2. Click [Administrator Tools] and enter the Administrator Login ID and Password.
3. Select [Clock and Calendar Settings] in the [Main Unit Settings] Menu.
4. Enter the current date and time, and click [Set Clock].
How to find an NTP server
If you are using a company internal LAN, in many instances an NTP server will already be set up to work in conjunction with the LAN. First, please ask your network administrator.
If you are connected to the Internet, please contact your provider. In many instances, the provider may provide connection to an NTP server as a part of their service. It is also possible to use any NTP server that is available to the general public on the Internet. By running a search for "NTP Server" on any search engine such as Yahoo or Google you will be able to find many such services. Many universities or scientific facilities will have an NTP server open to the public. Make sure to use a server which is closet to your location. (However, please make sure to check whether the connection is free and without limitation.)
It should also be noted that depending on your Internet connection and your firewall settings, the NTP packet may be prohibited from being accepted into your system.
