It is rare for a Starter or Clearing unit to have an isolated issue. If you find one or more Trackers are not responding to a unit, please check the following:
- Attempt to Start / Clear several Trackers from that unit. If any Tracker responds to the unit with a vibration, there is not an issue with that Starter or Clearer, rather it may be an issue with the Tracker or network. If no Trackers respond with a vibration, but do so on a different Start / Clear unit, you may have a problem with that Start / Clear unit.
If you think it might be a Tracker issue, read the Troubleshooting Trackers article.
