82 > КА (ПІЛІ. LOCK)
This flow occurs when the dial lock switch is set in the lock position.
82 > K8 (Frequency UP)
This flow occurs when the frequency is moved up by turning the tuning control knob. When
the frequency is moved down, the R2 signal is not fed to K8.
23 > K1 (Memory 1)
This flow occurs when the VFO select switch is set at "Метогу 1".
83 > K2 (Memory 2)
This flow occurs when the VFO select switch is set at "Memory 2".
R3 > КА (Memory 3)
This flow occurs when the VFO select switch is set at "Memory 3"
In the condition of (9), (9, ог 7, when the flow of (2 occurs, the data іп "A" VFO is pro-
grammed in Memory Channel 1, 2 or 3, respectively.
R3 K8 (MS/MW) |
This flow occurs when the MS/MW button is pushed.
