Hardware communications between modules has failed. Insure that the battery level is
adequate for operation or that temperature is within acceptable limits. Reset to factory
defaults with either Factory Defaults, ESC+ON, or MASTER RESET, System+ON.
Caution: Use of MASTER RESET, System+ON, will erase all user saved setups and
measurement traces and return the unit to a fully Factory Default condition. If the error
persists, then contact your Anritsu Service Center.
