This is useful when searching for signals around a memory channel frequency and for recalling the offset frequency, subaudible tone frequency etc. D Memory/callVFO q Select the desired band's (left or right) memory or call channel. Push the desired band's [M/CALL·MW] several times to select memory mode or call channel, then rotate the same band's [DIAL] to select the desired memory or call channel. to transfer the selected memory/call channel contents to the VFO. · VFO mode is selected automatically. MR/CALL MW [Y]/[Z] z Push [BAND] to select the desired band as the main band, if necessary. x Select the memory/call channel to be transferred. Push [MR/CALL] to select memory mode, then select the desired memory channel via [Y]/[Z] or keypad. then push [Y]/[Z] to select the call channel. c Push [FUNC], then [CLR A(MW)] for 1 sec. to transfer the selected memory/call channel contents to the VFO. · VFO mode is selected automatically. 5 [EXAMPLE]: Transferring memory channel 30 contents to VFO. Front panel operation: Push M/CALL to select memory mode. Rotate MW MAIN TX for selecting memory channel. MAIN TX DUP T Push M/CALL MW for 1 sec.
