Poor signal alarm.

[Ennerdale]

My moto g6 gives an alarm sound when the signal level drops, I usually average about - 110 dB signal strength,  but if the signal goes below this perhaps down to -140 dBm the alert sounds. In my area this happens quite a few times a day. Can I silence it? Thank you.

@Ennerdale  Not sure if THIS will help but look under advanced sounds

Edge of cell is usually around the -125dBm mark, so this sounds even more extreme than an "I have no coverage" alarm!!
