2. Tune Field RADs

The method to tune the field RAD is by observation of an armed tag’s alarming status by touring all

the nearby RADs to make sure the tuned RAD’s radiation coverage can cover all the nearby RADs.

If tag alarms at some corner, it means the RAD under tuning has a low radiation field and can not

cover this corner. Operator can increase the radiation level of the RAD to cover this dead corner.
