Several scanning options, screen backlight adjustment of brightness and contrast, weather alert on or off, time location and offset, foghorn frequency, and speaker tone controls are operated through the radio setup menu.
A low battery warning message appears onscreen when input power drops below 11.8 volts. Increasing the voltage back above 12.5 turned the warning off.
