So, if I go to MENU then SETTINGS, then SET BACKLIGHT, then SET MODE, then set it to SQUELCH, the display backlight is supposed to be on constantly while the voice transmission is in progress, yeah? Except, that doesn't happen! The backlight comes on for five seconds at the beginning of the transmission, then it goes off. I've tried setting it to stay on squelch both through the unit's menu and via software upload settings, but no dice... it will not stay on constantly. My BC125AT does it correctly, as does my 436, but the 325P2, no. Ideas?
