SAVE THIS INSTRUCTION MANUAL-- This instruction manual contains important operating instructions for the transceiver. Icom, Icom Inc. [. . . ] In this display pre-programmed memory channel names are displayed. VFO mode is selectable. · Programmed frequencies are indicated pre-programmed in the selected memory channel. · Push and hold [SQL] to display the operating frequency. 20 REPEATER OPERATION I General 5 4 5 When using a repeater, the transmit frequency is shifted from the receive frequency by the offset frequency. It is convenient to program repeater information into memory channels. q Set the receive frequency (repeater output frequency). w Push [A·FUNC], then push [4·DUP] several times to select "­" or "+. " · "­" indicates the transmit frequency is shifted down; "+" indicates the transmit frequency is shifted up. · Blinking "­" or "+" indicates the reversed duplex mode is selected in SET MODE (p. e Push [A·FUNC], then push [1·TONE] to activate the subaudible tone encoder, if required. · " " appears · Select the desired subaudible tone frequency, if necessary. · The displayed frequency automatically changes to the transmit frequency (repeater input frequency). · If "OFF" appears, check the offset frequency (p. y Push and hold [SQL] to check whether the other station's trans- mit signal can be directly received or not. About reversed duplex mode When the reversed duplex mode is selected, the receive frequency shifts. (Transmit frequency shifts in normal duplex mode. ) Each receive and transmit frequency is shown in the table below with the following conditions; Inputed freq. : 145. 30 MHz Reversed OFF ON Direction : ­ (negative) Rx frequency 145. 30 MHz 144. 70 MHz Offset frequency : 0. 6 MHz Tx frequency 144. 70 MHz 145. 30 MHz 21 5 REPEATER OPERATION USING I Offset frequency SET MODE When communicating through a repeater, the transmit frequency is shifted from the receive frequency by an amount determined by the offset frequency. q Push [A·FUNC], then push [8·SET] to enter SET MODE. w Push [Y] or [Z] several times until "±" and offset frequency appear. e Rotate [VOL] to select the desired offset frequency. · Selectable steps are the same as the pre-set tuning steps. · The unit of the displayed offset frequency is "MHz. " r Push [#·ENT ] to fix the offset frequency and exit SET MODE. USING I Subaudible tones SET MODE Some repeaters require subaudible tones to be accessed. Subaudible tones are superimposed over your normal signal and must be set in advance. q Push [A·FUNC], then push [8·SET] to enter SET MODE. F MR TX w Push [Y] or [Z] one or more times until "rt" appears. e Rotate [VOL] to select the desired subaudible tone. r Push [#·ENT ] to enter the selected tone and exit set mode.

DTMF TONES While pushing [PTT], push the desired DTMF keys (0­9, A­F) to transmit DTMF tones. · The transceiver has 5 DTMF memory channels (p. 30). 5 1750 Hz TONE While pushing [PTT], push [Y] or [Z] to transmit a 1750 Hz tone signal. Convenient Tone scan function: When you don't know the subaudible tone used for a repeater, the tone scan is convenient for detecting the tone frequency. Push [A·FUNC], then push [3·T. SCAN] to start the tone scan. · Push [D·CLR] to cancel the scan. · When the required tone frequency is detected, the scan pauses. 23 5 REPEATER OPERATION USING I Auto repeater function (USA version only) INITIAL SET MODE The USA version automatically activates the repeater settings (duplex, ON/OFF, duplex direction, tone encoder ON/OFF) when the operating frequency falls within or outside of the general repeater output frequency range. The offset and repeater tone frequencies are not changed by the auto repeater function. Reset these frequencies, if necessary. q While pushing [Y] and [Z], turn the power ON to enter SET MODE.
