User manual ICOM IC-A4

[. . . ] This radio has been evaluated for compliance at the distance of 2. 5 cm with the FCC RF exposure limits for "Occupational Use Only". In addition, your Icom radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: · FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. · American National Standards Institute (C95. 1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. · American National Standards Institute (C95. 3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields­ RF and Microwave. [. . . ] to turn power ON, then push [CLR·DEL] to select the frequency mode when memory CH number or WX CH number appears on the function display. Push again to return the normal tuning. w Rotate [DIAL] to select the desired WX channel. e Push [CLR·DEL] to exit the WX channel mode and return to frequency mode. 8 3 BASIC OPERATION I Receiving q Push [PWR] to turn the power ON. w Push [SQL·WX-ALERT], then rotate [DIAL] counterclockwise to select the squelch level 0. r Push [SQL·WX-ALERT], then rotate [DIAL] clockwise until the noise is muted. ·" " indicator disappears. I Transmitting CAUTION: Transmitting without an antenna may damage the transceiver. t Set the desired frequency using [DIAL] or keypad. y When a signal is received on the set frequency: ·" " indicator appears. · Squelch opens and audio is emitted from the speaker. NOTE: To prevent interference, listen on the frequency before transmitting. q Set the desired frequency in COM band using [DIAL] or keypad. · COM band frequency range: 118. 00­136. 975 MHz When [SQL] control is too "tight, " squelch may not open for weak signals. To receive weaker signals, loosen the squelch w Push and hold [PTT] to transmit. ·" " indicator appears. e Speak into the microphone at a normal voice level. · DO NOT hold the transceiver too close to your mouth or speak too loudly. This may distort the signal. r Release [PTT] to return to receive. I ANL function The ANL (Automatic Noise Limiter) function reduces noise components such as that caused by engine ignition systems while receiving. · Push [ANL·SCAN] to turn the ANL function ON/OFF. " " appears on the display while the ANL function is ON. 9 BASIC OPERATION 3 I Low battery indicator Low battery indicator appears Low battery indicator when the battery power has decreased to a specified level. q Push [MR·MW] to select memory mode. · Memory BANK number and memory CH. number appears. 4 3 4 I Transferring memory contents This function transfers a memory channel's contents into the frequency mode. This is useful when searching for signals around a memory channel's frequency. w Select the desired memory channel to be transferred using [DIAL] or keypad. e Push , then push [MR·MW] to transfer the memory channel's contents into the frequency mode. number disappears as frequency mode is automatically selected and the memory contents are transferred. Using [DIAL]: w Push [0·BANK], then rotate [DIAL] to select the desired memory BANK number, then push [0·BANK] (or [CLR·DEL]) to exit the BANK selection mode. · "BANK" appears. e Rotate [DIAL] to select the desired memory CH. selection is available. Using the Keypad: w Push [0·BANK], then push appropriate digit key ([0·BANK] to [9·TAG]) to select the desired memory BANK number, then push [0·BANK] (or [CLR·DEL]) to exit the BANK-selection mode. · "BANK" appears. e Push 2 appropriate digit key (00 to 19) to select the desired memory CH. Memory mode Frequency mode NOTE: Comments appear first when programmed, however, the transceiver can be programmed by your dealer to show the operating frequency first. Push [MR·MW] to display the comment in this case. 12 4 MEMORY OPERATION I Programming a memory channel The transceiver has 200 (20 CH. × 10 BANK) memory channels for storage of often-used frequencies. w Select the desired frequency. · Push , then push [ENT·WX] to select a weather channel. * · Set the desired frequency or weather channel* using [DIAL] or keypad. · EXAMPLE: Programming WX-05* into memory BANK 3/ memory channel 9.
