[. . . ] i7800 Instruction Manual THE TRANSCEIVER A-6328H-1EX-r Printed in Japan © 2004 Icom Inc. FOREWORD Congratulations!You are the owner of the world's most advanced amateur HF/50 MHz transceiver-- IC-7800. The IC-7800 is designed and built with Icom's superior technology and craftsmanship. With proper care, this product should provide you with years of trouble-free operation. [. . . ] · "<<" or ">>" appears when the marker is out of range. · The spectrum scope shows the transmit signal waveform while transmitting. 5-4) · The spectrum scope shows the peak level holding function. 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) · Observed indication example i Push [F-4·HOLD] to freeze the current spectrum waveform. · " HOLD " appears while the function is in use. · The peak hold function can be deactivated in scope set mode. o Push [EXIT/SET] to exit the scope screen. Push [F-2·ATT] 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. 5-2 FUNCTIONS FOR RECEIVE 5 D Fix mode Displays signals within the specified frequency range. The selected frequency band conditions can be observed at a glance when using this mode. [F-2·ATT] [F-4·HOLD] [F-5·CENT/FIX] q Push [EXIT/SET] several times to close a multifunction screen, if necessary. e Push [F-5·CENT/FIX] to select the fix mode. ·" " is displayed when fix mode is selected. r Push [F-2·ATT] several times to activate an attenuator or turn the attenuator OFF. · 10, 20 and 30 dB attenuators are available. t Push [F-6·MAIN/SUB] to select main band. [F-3·MARKER] [EXIT/SET] [F-6·MAIN/SUB] · The spectrum scope with sub band selection is activated during dualwatch or split frequency operation only. y Push [F-3·MARKER] several times to select the marker (sub readout or transmit frequency) or turn the marker OFF. ·" " displays the marker at the main readout frequency. (always displayed) ·" " displays the marker at the transmit frequency. ·" " displays the marker at the sub readout frequency. · "<<" or ">>" appears when the marker is out of range. · The spectrum scope shows the transmit signal waveform while transmitting. 5-4) · The spectrum scope shows the peak level holding function. 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) u Push [F-4·HOLD] to freeze the current spectrum waveform. · " 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 [F-2·ATT] several times to activate the spectrum scope attenuator in this case. The scope bandwidth can be specified for each operating frequency band independently in scope set mode.
