elsewhere in this manual, only one of the radio options can be installed in the printer at one time and the
antenna used for this transmitter must not be co-located or must not operate in conjunction with any other
antenna.

configuration with no minimum separation. In this configuration, which
applies whether the belt clip or shoulder strap is used, the face of the
printer from which paper is transported is facing away from the user’s
body. The standard configuration must always be used when the printer
