Calibration consists in finding the offset in frequency between the internal clock and a NTP reference and is necessary
for normal operation of NTP.
The calibration process is started automatically and will take approximately 60 minutes when at least one NTP server
(other than loopback) is available. Once the calibration data is saved, it is reused when the device is rebooted or powered
off.
To calibrate the clock of an IS-SPX Player:
1. Start the player.
2. In your Web browser, open the player’s Browser-Based Configuration Pages.
3. Look at the NTP statistics section of the Date/Time page. If the end of the NTP statistics section states that the clock
is calibrated, no more operations are required. If the clock is not calibrated, continue this procedure.
4. Check that at least one NTP server other than loopback is reachable and selected as peer.
5. Allow for some time in order for reachable servers to become peers.
6. If no NTP servers are reachable, check that the NTP servers are correct and that the network configuration is
working. If not, modify the settings and restart the procedure.
7. Once a peer other than loopback is selected, leave the device running for at least 70 minutes without rebooting.
8. After 70 minutes, the local clock should be calibrated. Reboot the device from the Browser-Based Configuration
Pages. Do NOT unplug the device before rebooting.
