Band keys q Connect a PC and TNC to the transceiver. r Push DATA to turn data mode ON. · One of "-D1, " "-D2" or "-D3" is additionally appears. to select data mode 1 (D1), 2 (D2) and 3 (D3) in sequence. [AF] SSB AM/FM DATA Main dial t Rotate the main dial to tune to the desired signal and decode it correctly. · Also use the tuning indicator of the TNC or software. · During SSB data mode, the 1/4 tuning function can be used for critical tuning. Appears y Operate the PC (software) or TNC to transmit. · When operating in SSB data mode, adjust the TNC output level so that the ALC meter reading doesn't go outside the ALC zone. NOTE: When SSB data mode is selected, the audio input from the [ACC1 (pin 6)] is used for transmission instead of [MIC]'s. 12-7, 12-8)) The fixed condition is used for SSB data transmission as follows: · [COMP] : OFF · Tx bandwidth : MID · Tx Tone (Bass) : 0 · Tx Tone (Trebles): 0 · Tone-pair example 2325 Hz 200 Hz 2125 Hz For your information Carrier frequency is displayed when SSB data mode is selected.

Peak levels are displayed in the background of the current spectrum in a different color until the receive frequency changes. This can be deactivated and the waveform color can be set in scope set mode. 5-5) · Scope spurious signal example Spurious signals may be received on the spectrum scope screen regardless of the transceiver's state (TX or RX). This does not indicate a transceiver malfunction. u Push [HOLD] F-4 to freeze the current spectrum display. · " HOLD " appears while the function is in use. · The peak hold function can be deactivated in scope set mode. i Push EXIT/SET to exit the scope screen. Push [ATT] F-2 several times to activate the spectrum scope attenuator in this case. They are generated in the internal scope circuit and do not indicate a transceiver malfunction. Scope spurious example 5-2 FUNCTIONS FOR RECEIVE 5 D Fixed mode Displays signals within the specified frequency range. [. . . ] i Click [Yes] if you want to start the firmware update.
