3 / 24 page 3 Brief Introduction to The CM1481 Brief Introduction to The CM1481 Brief Introduction to The CM1481 Brief Introduction to The CM1481 Brief Introduction to The CM1481 The CM1481 is a compact 5- or 6-Tone CCIR, EEA and ZVEI selcall module with individual address encoding, non-predictive all-tone decoding, transponding and full, all-system GROUP Call and ANI capabilities. In addition to normal selcall facilities, the CM1481 offers, as standard, a range of over-air control facilities to allow a base-station additional control when working with remote units. These added facilities are: ‘Stun’ and ‘Release’ - To allow the controller to completely ‘freeze’ all module and parent radio audio functions rendering it inoperative until ‘Released’. This to counter theft, air misuse/abuse or non-payment of fees. ‘Re-Configuration’ - To change module addresses and modes via an over-air command. This to allow unit participation in other user groups.

The unit may be muted by the base. Under the control of its on-board µController, operating from instructions written to it by a simple menu-driven configuration operation from a basic 'PC' type computer, the CM1481 can completely control the workings of the radio's Rx and Tx audio processes. After Configuration the only operator inputs required are Microphone/Handset, Volume and Selcall Tx/Mute controls. The CM1481 will detect and decode all incoming tone information, controlling the radio functions whilst providing the operator with various coded audio alerts to indicate status and progress.
