SSB (USB/LSB), SSB data (USB data/LSB data), CW, CW reverse (CW-R), RTTY, RTTY reverse (RTTY-R), PSK, PSK reverse (PSK-R), AM, AM data, FM and FM data modes are available in the IC-7700. Select the desired operation mode as follows.

To select a mode of operation, push the desired mode switch momentarily. Push the switch again to toggle between USB and LSB, CW and CW-R, RTTY/RTTY- R and PSK/PSK-R, AM and FM, if desired. Push and hold the switch for 1 sec. to toggle between RTTY and RTTY-R, PSK and PSK-R, if desired.

See the diagram below left for the order of selection.

Microphone signals are muted when data mode is selected.

• Selecting SSB mode

➥ Push SSB to select USB or LSB.

•USB is selected first when above 10 MHz; or LSB is se- lected first when below 10 MHz operation.

(USB is selected when 5 MHz band is selected for the

USA version.)

• After USB or LSB is selected, push SSB to toggle between USB and LSB.

• Selecting CW mode

➥ Push CW to select CW.

• After CW is selected, push CW to toggle between CW and CW reverse mode.

• Selecting RTTY/PSK mode

➥Push RTTY/PSK to select RTTY or PSK.

•After RTTY or PSK is selected, push RTTY/PSK to toggle between RTTY and PSK.

•After RTTY or PSK is selected, push and hold RTTY/PSK for 1 sec. to toggle between RTTY and RTTY reverse, or, PSK and PSK reverse mode, respectively.

• Selecting AM/FM mode

➥Push AM/FM to select AM or FM.

•After AM or FM is selected, push AM/FM to toggle be- tween AM and FM.

• Selecting DATA mode

➥After USB, LSB, AM or FM is selected, push DATA to select USB data, LSB data, AM data or

FM data mode, respectively.

• After data mode is selected, push DATA to toggle between regular voice and data mode.

• After data mode is selected, push and hold DATA for 1 sec. to select data 1, 2 and 3 in sequence.
