285REPEATER AND DUPLEX OPERATIONS12345678910111213141516171819■ 1750 Hz toneTo access some European repeaters, the transceiver musttransmit a 1750 Hz tone burst. For such repeaters, performthe following.• This tone can be use as a ‘Call signal’ in countries out of Europe.qPush [SET] to enter the Set mode.wRotate [DIAL] to select the DTMF key item, then rotate[VOL] to set to “t-CALL.”[VOL][DIAL]Tone call settingDTMF key settinge Push [V/M/C] to return to the frequency display.r Set the receive frequency (repeater output frequency).t Set the shift direction of the transmit frequency. (–DUP or+DUP; see p. 26 for details.)y While continuing to push [PTT], push [MONI](BAND) totransmit a 1750 Hz tone burst signal.• If “OFF” appears, check the frequency offset or shift direction.(p. 26)• The displayed frequency automatically changes to the transmitfrequency (repeater input frequency).u Push and hold [PTT] to transmit.i Release [PTT] to receive.o Push and hold [MONI](BAND) to check whether the otherstation’s transmit signal can be received directly or not, bylistening on the repeater input frequency.✔ CONVENIENT! (For the IC-T70E only)q Set the receive frequency (repeater output frequency).w Set the shift direction of the transmit frequency. (–DUP or+DUP; see p. 26 for details.)e Push [PTT] briefly, then push and hold [PTT] again for 1 to2 sec. to transmit a 1750 Hz tone burst signal.• If “OFF” appears, check the frequency offset or shift direction.(p. 26)• The displayed frequency automatically changes to the transmitfrequency (repeater input frequency).r Push and hold [PTT] to transmit; release to receive.
