User manual ICOM IC-T7H

[. . . ] INSTRUCTION MANUAL DUAL BAND FM TRANSCEIVER iT7H This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL--This instruction manual contains important operating instructions for the IC-T7H. CAUTIONS RWARNING!NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. [. . . ] 24). 1750 Hz TONE (Europe and Italy versions only) While pushing [PTT], push and hold [TONE] for 1 to 2 sec. 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. 22 for more information. Push [TONE] to activate the subaudible tone encoder, according to repeater requirements. · "T" appears. · Refer to the table of tone frequencies on the following page. Push and hold [PTT] to transmit. · The displayed frequency automatically changes to the transmit frequency (repeater input frequency). · If "OFF" appears, check the offset frequency (p. Push and hold [MONI] to check whether the other station's transmit signal can be directly received or not. 13 3 BASIC OPERATION D Setting an offset frequency D Setting subaudible tones for repeater use USING SET MODE USING SET MODE Some repeaters require subaudible tones to be accessed. Subaudible tones are superimposed over your normal signal and must be set in advance. When communicating through a repeater, the transmit frequency is shifted from the receive frequency by an amount determined by the offset frequency. Push [VFO] to select VFO mode. Push [TONE] or [H/L] several times until "rT" appears. Rotate [DIAL] to select the desired subaudible tone. Push [(VFO)CLR] to exit set mode. T Push [VFO] to select VFO mode. to enter set mode. DUP Push [TONE] or [H/L] several times T until "OW" appears. Rotate [DIAL] to select the desired offset.

Push [(VFO)MHz] to exit set mode. s Auto low power When transmitting for 6 continuous min. at high power, the IC-T7H automatically selects low power. This function cannot be turned OFF and activates when the power supply is at approx. To return to high power on transmit, select receive, then switch back to transmit. 14 ADVANCED FUNCTIONS s Memory/call channels The transceiver has 70 memory channels (60 regular, 4 pairs of scan edge channels for mixed bands and 1 call channel for each band). Note that memory channels are not grouped according to band. In other words, a given memory channel can be programmed with either a VHF frequency or a UHF frequency. This is not the case with call channels. The following can be programmed into memory/call channels: · Operating frequency · Duplex direction with an offset frequency (pgs. 13, 14) · Subaudible tone encoder or tone squelch ON/OFF with a tone (CTCSS) frequency (pgs.
