The R4BLK menu system is 2-tiered; Basic and Expert. Basic level menus let you set
basic elements such as red light camera alarms, band announcement (voice), and
how you want the OLED to appear (Alert Display #1 or #2 menu option, for example),
among other options. Expert level menus allow you to fine-tune your detector by
activating the traffic sensor filter, turning threat notifications on and off, or changing
the colors on the OLED screen, among other options.
In addition, GPS can be turned on and off only through the Expert menus. GPS status
also affects which menus may display in the Basic or Expert levels. For example, if
GPS is turned on, then the Speed Camera Alarm menus display. If it is not turned on,
then those menus will not display.
If a menu depends on Level, Mode, GPS , or a different status, that dependency will
be noted in the specific menu entry itself.
The following table lists all the menu options from all levels and modes.
Several menu items only display if GPS is set to ON. These entries are noted in the
