The TCB-550N has been designed with slim and compact design features enabling it to be easily installed in modern vehicles where space is at a premium.
The TCB-550N includes a novel Auto Squelch function that works very well in the FM mode; the squelch control can be turned fully anti-clock wise till it is locked in to Auto Squelch mode, by turning the squelch control clock-wise Auto Squelch is disabled and you can manually adjust squelch level to your desired level. It is also multi-standard so it is one of the lowest price radio that can be used across Europe, an ideal starting point for a first time CB user.
