13.2 Reboot the transmitter
Display Menu > Service Tools > Reboot Transmitter
ProLink III Not available
Field Communicator Service Tools > Maintenance > Reset/Restore > Device Reset
For certain configuration changes to take effect, the transmitter must be rebooted. You must also reboot the
transmitter in order to clear certain status alerts.
Rebooting the transmitter has the same effect as power-cycling the transmitter.
Prerequisites
Follow appropriate procedures to select the appropriate time for rebooting the transmitter. The reboot
typically takes about 10 seconds.
Postrequisites
Check the transmitter clock. During the reboot, the transmitter clock is powered by the battery, therefore the
transmitter clock and all timestamps should be accurate. If the transmitter clock is not correct, the battery
may need replacement.
13.3 Battery replacement
The transmitter contains a battery that is used to power the clock when the transmitter is not powered up.
Users cannot service or replace the battery. If the battery requires replacement, contact customer support.
If the battery is non-functional and the transmitter is powered down, then powered up, the clock will restart
from the time of the power-down. All timestamps will be affected. You can correct the issue by resetting the
transmitter clock. For a permanent resolution, the battery must be replaced.
