What is the Disconnect Tone Detect function?
When monitoring Motorola systems, the radio knows to stop monitoring a transmission and return to the control channel when it detects a series of sub-audible “disconnect” tones. Unfortunately, on some systems, outside interference can trick the radio into thinking it has received these tones. The result? The radio will abandon a transmission before it is completed which can be very frustrating to the listener. Early model BC235XLTs had this problem which was rectified in later production runs by including the ability to turn off this Disconnect Tone Detect function. The BC245XLT comes with this ability and it’s accessed by pressing the SVC key while monitoring a Motorola sytem. The radio should beep twice and the DATA icon should be flashing. This feature is now disabled. Repeat the process to enable it. With this feature disabled, the radio will only leave a transmission when the squelch closes.
