User manual ICOM IC-718

[. . . ] INSTRUCTION MANUAL HF ALL BAND TRANSCEIVER i718 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 THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the transceiver. EXPLICIT DEFINITIONS WORD R WARNING CAUTION NOTE DEFINITION Personal injury, fire hazard or electric shock may occur. No risk of personal injury, fire or electric shock. SAVE THIS INSTRUCTION MANUAL. This manual contains important safety and operating instructions for the IC-718. PRECAUTIONS R WARNING HIGH VOLTAGE! [. . . ] r Select "VOX Delay" in quick set mode. · Push [ UP]/[ DN] one or more times to select "VOX Delay" t While speaking into the microphone, adjust [VOX DELAY] as desired. y Select "ANTI-VOX" in quick set mode. · Push [ UP]/[ DN] one or more times to select "AN VOX" u If the receive audio from the speaker toggles the transceiver to transmit during receive, adjust the "ANTI-VOX" to the point where it has no effect. i Push [SET] to exit the quick set mode. 27 5 RECEIVE AND TRANSMIT ï Optional AT-180 AUTOMATIC ANTENNA TUNER operation The AT-180 automatic antenna tuner matches the IC718 to the connected antenna automatically. Once the tuner matches an antenna, the variable capacitor angles are memorized as a preset point for each frequency range (100 kHz steps). Therefore, when you change the frequency range, the variable capacitors are automatically preset to the memorized point. · MANUAL TUNING During SSB operation on HF bands at low voice levels, the AT-180 may not be tuned correctly. to start manual tuning. · CW mode is selected, a side tone is emitted, and " " blinks; then, the previous mode is selected. CAUTION: NEVER transmit with the tuner ON when no antenna is connected. This will be damage both the transceiver and the antenna tuner. DO NOT!Both turners will not be function correctly. Y Y TUNER OPERATION [TUNER] · Tuner type setting (p. 46) q Push [PWR] for 1 sec. r Rotate the main dial to select "18". · AT-180 AUTOMATIC ANTENNA TUNER is selected. NOTE: NEVER select "4" (AH-4 AUTOMATIC ANTENNA TUNER), otherwise the transceiver trans- Push and hold 1 sec. to start manual tuning. If the tuner cannot reduce the SWR to less than 1. 5:1 after 20 sec. In this case, check the following: · the antenna connection and feedline · the antenna SWR (p. u Push [PWR] to turn power ON again. · AUTO TUNE: Push [TUNER] to turn the tuner ON. The antenna is tuned automatically during transmission when the antenna SWR is higher than 1. 5:1. · When the tuner is OFF, " " goes out. · Through inhibit The AT-180 has a through inhibit condition. When selecting this condition, the tuner can be used at poor SWR's. In this case, automatic tuning in the HF bands activates only when exceeding SWR 3:1. Therefore, manual tuning is necessary each time you change the frequency. Although termed "through inhibit, " the tuner will be "through" if the SWR is higher than 3:1 after tuning. CONVENIENT · Tuner sensitive condition If you require critical tuning at any time during transmission, select the tuner sensitive condition. · Automatic tuner start If you want to turn OFF the tuner under conditions of VSWR 1. 5:1 or less, use "automatic tuner on" and turn the tuner OFF. 46 for turning the function ON and OFF.
