Push this switch to use operating modes such as PACKET or AMTOR
communications which require rapid receive and transmit switching
times.
Rotate this control clockwise to increase frequency numbers and
counterclockwise to decrease them.
e Quick, continuous rotation of the TUNING CONTROL changes
the frequency up or down by 10kHz. Siow rotation changes it by
2.5kHz, except when using FM mode.
Push this switch to increase the tuning step by 1kHz while operating
in any mode. Push and release the switch again to return to the
previous tuning step.
This switch sets the tuning step rate for 1MHz steps in any mode.
This switch selects VFO A or VFO B for tuning purposes. Each
push of this switch selects one of the two VFOs alternately.
This switch also selects VFO A or VFO B mode from the MEMORY
CHANNEL or CALL CHANNEL mode.
This switch selects the relationship of the two VFO frequencies. In
the IN position, one VFO is for receive while the other VFO is for
transmit. Each alternate push of this switch chooses the simplex and
duplex modes.
This switch electronically locks the display frequency and deactivates
the TUNING CONTROL. Push the switch IN and a beep sound is
emitted, indicating that the function has been activated.
This switch selects the CALL CHANNEL which is most frequently
used as a call frequency.
This switch operates differently depending on which mode the
transceiver is т.
