User manual ICOM IC-T8A-E

[. . . ] The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 in) away from the lips and the transceiver is vertical. SAVE THIS INSTRUCTION MANUAL--This instruction manual contains important operating instructions for the IC-T8A-E/E. EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. DEFINITION Personal injury, fire hazard or electric RWARNING shock may occur. CAUTION NOTE If disregarded, inconvenience only. No risk of personal injury, fire or electric shoc Versions of the IC-T8A-E/E which display the "CE" symbol on the serial number seal, comply with the European harmonised standard ETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). RWARNING! [. . . ] Set the squelch level. · While pushing [SQL], rotate [DIAL]. · 10 selections are available, "OPEN, " "AUTO, " and "SQL 1 to "SQL 8. " 9 MR Set an operating band and frequency. 9 MR Push [H/L] to toggle output power between high and low. · "LOW" appears when low output power is selected. · When a signal is received: Squelch opens and audio is emitted from the speaker. The [TX/RX] indicator lights green. Push and hold [PTT] to transmit; then speak into the mic. · Do not hold the microphone too close to your mouth or speak too loudly. · The S/RF indicator shows the output power selection. · The [TX/RX] indicator lights red. I Lock function Push [(H/L)LOCK] for 1 sec. to toggle the lock function on and off. · "L" appears while the lock function is activated. · [PTT], [PWR], [MULTI()] (volume), [SQL] and [H/L] can be used even when the lock function is activated. Release [PTT] to return to receive. CONVENIENT Monitor function: Push and hold [SQL] to listen to weak signals that do not open the squelch. 11 4 BASIC OPERATION play, then rotate [DIAL] to select a frequency; or, I FM broadcast reception The transceiver can receive FM radio broadcasts. These are typically in the range 76­107. 995 MHz (88­107. 995 for some versions) and are in WFM receive mode. To select the FM broadcast band: W FM Push [MULTI()] one or more times until "WFM" appears in the display, then rotate [DIAL] to select a frequency; or, Select a frequency with the digit keys directly. · "WFM" automatically appears when a frequency in the range 76­107. 995 MHz is input. Select a frequency with the digit keys directly. · "AM" automatically appears when a frequency in the range 118­135. 995 MHz is input.  NOTE: When pushing [PTT], "OFF" appears indicating the frequency and mode are outside the permitted range. SET MODE I Narrow FM* operation (Europe, France, Italy ver. ) USING Push [MULTI()] one or more FM  NOTE: When pushing [PTT], "OFF" appears indicating the frequency and mode are outside the permitted range. I Air band reception (Asia, USA ver. ) The transceiver can receive frequencies reserved for commercial/private aircraft and ground support. These are in the range 118­135. 995 MHz and are in AM receive mode. In this case, precede step at left with the required tone. DTMF TONES While pushing [PTT], push the desired digit key(s) to transmit DTMF tones. · The transceiver has 9 DTMF memory channels. 21 for details. Set the operating band and receive frequency (repeater output frequency). Push [MULTI] to enter duplex set mode. · "D" appears; if "T" appears instead of "D" push [MULTI()] to select "D. " Push [MULTI()] (or rotate [DIAL]) one or more times to select DUP ( plus duplex) or ­DUP (minus duplex). · When the auto repeater function is in use (USA version only) steps , , and are not necessary (p. · "T" appears. 1750 Hz TONE While pushing [PTT], push and hold [MULTI] for 1 to 2 sec. 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. 26 for more details. Push [MULTI()] to select tone set mode. Push [MULTI()] (or rotate [DIAL]) to activate the subaudible tone encoder according to repeater requirements. · Refer to the table of subaudible 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 [SQL] to check whether the other station's transmit signal can be directly received or not. 15 5 REPEATER OPERATION I Subaudible tones for repeater use USING SET MODE I Setting an offset frequency 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. to enter set mode. T Push [VFO] to select VFO mode. [. . . ] Squelch does not open for · Tone squelch is activated. Some memory channels · Some memories have been cleared. 18 RIT/VXO offset cannot be · RIT/VXO function has not been activated or the · Activate the RIT/VXO function in set mode or push p. Cannot transmit on the 50 · AM mode has been set for the 50 MHz band. [. . . ]
