opening is cut out for switching on the GSM-phone (Figure 4). The GSM phone must be equipped with
an automatic call accepted and the call accepted must be switched on. If the GSM-phone in the CT-

can talk with the external caller. The external caller can also listen the radio communication via the two-
way radio.
