Chassis-Mounted LEDs
On current production radios, a series of additional LEDs are located
behind the front panel affixed to the chassis. These indicators are prima-
rily 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 33).
