!5MENU

Lights while Menu mode is being accessed. Flashes when the Menu has been temporarily reset {page 24}.

!6A/B

“A” lights while Menu A is being accessed. “B” lights while Menu B is being accessed {page 24}.

!7SPLIT

Lights while a different transmit and receive frequency are selected for split frequency {page 42}.

!8RIT

Lights while the Receive Incremental Tuning function is ON {page 44}.

!9TONE

In FM mode, lights while the subaudible Tone function is ON while operating split frequency {page 39}.

@0XIT

Lights while the Transmit Incremental Tuning function is ON {page 45}.

@1NB

Lights while the Noise Blanker is ON {page 53}.

@2WIDTH

In all modes except SSB and AM, lights after the LO/WIDTH control is adjusted. Indicates that the number reported below it on the Display is the receive bandwidth {page 52}.

@3CTRL

Lights while data is being exchanged between a computer and the transceiver during computer control {page 50} or between two transceivers during Quick Data Transfer {page 65}.

@4SHIFT

In CW, lights after the HI/SHIFT control is adjusted. Indicates that the number reported below it on the Display is the shift of the receive pass band {page 51}.

@5

Shows the selected memory channel {page 55}, Menu No.{page 24}, and Automatic Mode boundary numbers {page 48}. The dot lights while a memory channel is locked out. This indicates that the channel will be skipped during Memory Scan {page 62}.

@6AUTO

Lights while Automatic Mode is ON {page 48}. Automatic Mode automatically controls the operating mode according to instructions that you provide.
