If the conditions are not acceptable, the user can switch to simplex mode by depressing the T button. In some situations (example: high ambient noise levels or stations in close proximity), the station must be operated in simplex mode at all times. Digital Models DEX-102 and DEX-202 Intercom Communication Modes Master Communication - Communication between two stations can be automatically enabled during the system start-up, or enabled/disabled by the master station. To enable communication depress 6T and the number of the radio channel. Refer to the "Listening to the Radio Channel" section of the Central Switch manual for more details. NOTE: The associated slave station must be configured to transmit to the radio channel. The LED on the front panel illuminates to indicate a call is in progress.
