ABSTRACT:
A device such as a receiver, transmitter and/or transceiver includes a battery casing and at least one circuit substrate having a plurality of terminals arranged to lie in a plane. The battery casing has an opening which extends in a plane substantially parallel to the plane of the circuit substrate terminals. A plurality of apertures at the bottom of the battery casing correspond in number and are positioned directly above the circuit substrate terminals. Information such as, but not limited to, an identification code can be written into the device by removing a battery casing cover and inserting a plurality of read/write terminals through the opening and apertures of the battery casing so as to engage the circuit substrate terminals. In reading or writing information into the device by an apparatus, an arm of the apparatus which includes the plurality of read/write terminals is rotatably swung upwardly to provide room for the device to be positioned on a table of the apparatus. The table includes two guide walls which extend substantially orthogonally to each other and lie in the same plane. In positioning the device on the table, a pair of side walls of the device are placed against the guide walls of the apparatus. The arm of the apparatus is then rotated toward the device to permit the read/write terminals of the apparatus to be inserted through the opening and apertures of the battery casing for contact with the circuit substrate terminals.
