Chassis-Mounted LEDs
On current production radios, a series of additional LEDs are located
behind the front panel on the chassis. These indicators are primarily for
use in troubleshooting the radio and show important details about the
status of the radio circuitry.
To view the chassis LEDs, remove the front panel by grasping it along
the bottom edge and pulling straight out (see Figure 34).
