Midland BizTalk Portable Communication Radio, Black, MB400

Key Features and Benefits: Emergency call You can send an emergency call alert tone to other radios on the same channel/frequency and privacy code to alert them of an emergency situation. Programmable side keys Two programmable side keys can be adjusted by using the programming software to select which of the following functions you would like to have quick access to. Cloning The programed settings from a MB400 radio can be directly transferred to another MB400 radio bypassing the need to individually program radios. Privacy codes CTCSS (Continuous Tone Coded Squelch) and DCS (Digitally Coded Squelch) allow several users to share the same channel frequency without disturbing each other. With CTCSS or DCS enabled, the channel is muted to all incoming signals unless they carry the same CTCSS or DCS tone. When a transmission with the same tone is received, the channel unmutes and the voice audio can be heard. When the transmission ends the channel becomes muted again. Transmissions that do not have the same tone will not be heard. Your MB400 radio has 142 privacy codes, which can be used on any channel. The selected privacy code may be different for each channel, but must be the same for a channel on all radios you wish to talk to. Programming a new privacy code overwrites any previous code programmed.
