Busy Channel Lockout If enabled via the programming software, this feature can prevent your radio interfering with other transmitting radios on the same channel. If you hold down the PTT key while the channel is in use, your radio will keep beeping and display text information Channel Busy!, alerting you to transmission prohibition. To stop beeping, please release the PTT key. When the channel is free, you can press and hold down the PTT key to transmit. Time-out Timer (TOT) The purpose of TOT is to prevent any user from occupying a channel for an extended period. If the preset time expires, the radio will automatically terminate transmission and keep beeping. To stop beeping, please release the PTT key. You must wait for a certain time period (preset by your dealer) to initiate another transmission. If the pre-alert function is set by your dealer, your radio will alert you to the TOT expiration in advance. Note: This feature is null in Emergency mode. Pseudo Trunking This feature can be enabled via the programming software. If your radio operates on a channel with this feature enabled and one time slot is already occupied, it can transmit and receive on the other free time slot, allowing you to communicate timely under emergent situations. MIC AGC If enabled via the programming software, your radio will process the audio signals during transmission, providing improved audio for the receiving radio. Operating Modes It 's designed to support multiple operating modes including:

. MPT Trunked Mode

. DMR/PDT Trunked Mode

. DMR/PDT Digital Conventional Mode

. Conventional Analog Mode The PD78X/PD78XG portables can include all of these modes. 34 The PD78X/PD78XG supports a full range of advanced digital trunking features, including talk group calls, priority scanning, emergency calls, late call entry, and dynamic reconfiguration. It performs autonomous roaming for wide area applications. High quality voice coding and robust audio components assure speech clarity. In the trunked modes, the user selects a communications "operating" system (i.e., DMR,PDT,MPT

) and group. While communicating in a trunked mode, channel selection is transparent to the user and is controlled via digital communication with the system controller. This provides advanced programmable features and fast access to communication channels. In Conventional Analog mode, the user selects a channel and communicates directly on that channel. A channel is a transmit/receive radio frequency pair. The exact operation of the radio will depend on the operating mode, the radio is programming, and the particular radio system. Most features described in this manual can be enabled through programming. Then refer to the corresponding section(s) within this manual for feature and operation information. Signaling Introduction The radio supports the following signaling. You can ask your dealer to make appropriate settings on your radio. For detailed information, please contact your dealer.
