A printer that enables a determination whether a failure has occurred in a device during initialization or a radio wave condition is bad. Receive electric field strength during a time period from a time at which a turn-off message is outputted to a time at which turn-on message is outputted and receive electric field strength after the turn-on message is outputted are measured. The measurements are compared with each other and information indicating the condition of each of a plurality of channels is printed out according to the results of the comparison. A user can reference the printed information to determine whether a failure has occurred in a device or the radio wave condition is bad.
