User manual ICOM IC-4008E

[. . . ] 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. R WARNING!NEVER operate the transceiver with a headset or other audio accessories at high volume levels. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below ­10°C (+14°F) or above +55°C (+131°F). DO NOT modify the transceiver for any reason. The use of non-Icom battery packs/chargers may impair transceiver performance and invalidate the warranty. . 26 iv 1 PANEL DESCRIPTION ` Switches, controls, keys and connectors q ANTENNA !1 SP/MIC JACKS !0 [VOL] o DISPLAY w [PTT] e [UP] r [DOWN] t SPEAKER i [POWER] u [MODE] y MIC 1 PANEL DESCRIPTION 1 q ANTENNA Extend the antenna completely when using the transceiver.

A squelch circuit allows you to mute undesired noise while receiving no signal and emit audio while receiving signals. This is useful to listen to weak signals that do not open the squelch. 8 4 BASIC OPERATION ` Selecting the operating channel Push [UP]/[Y] or [DOWN]/[Z] keys several times until the desired operating channel number appears on the display. · While pushing and holding [UP]/[Y] or [DOWN]/[Z] keys, the displayed channel changes continuously until channel number " 1 " appears. If you want to keep the automatic selection, release the [UP]/[Y] or [DOWN]/[Z] keys then push and hold them again. UP R POWE MODE DO W N · When displayed channel stops at channel number "01", a warning beep is emitted. · The selected channel is memorised when you turn off the transceiver. 9 RECEIVE AND TRANSMIT q Push and hold [MODE] 1sec. CTCSS (Continuous Tone Coded Squelch System) GROUP MODE allows communication with silent stand by. This conveniently eliminates unwanted audio and is useful in group activities or security related activities where unwanted output can be a problem. Note that CTCSS group mode is not private--anyone can receive your calls. Each push of [PTT] superimposes your group code over your transmit signal; and, only signals containing the same code can open your squelch. To temporarily hear all signals (including noise) push and hold [MODE]. Do not use CTCSS GROUP MODE if you want to be able to hear signals on all channels. 12 6 CTCSS: Continuous Tone Coded Squelch System D CTCSS code table CH 01 02 03 04 05 06 07 08 09 10 Freq. 67. 0 71. 9 74. 4 77. 0 79. 7 82. 5 85. 4 88. 5 91. 5 94. 8 CH 11 12 13 14 15 16 17 18 19 20 Freq. 97. 4 100. 0 103. 5 107. 2 110. 9 114. 8 118. 8 123. 0 127. 3 131. 8 CH 21 22 23 24 25 26 27 28 29 30 Freq. 136. 5 141. 3 146. 2 151. 4 156. 7 162. 2 167. 9 173. 8 179. 9 186. 2 CH 31 32 33 34 35 36 37 38 --Freq. 192. 8 203. 5 210. 7 218. 1 225. 7 233. 6 241. 8 250. 3 OFF (unit: Hz) Talk Range The IC-4008E is designed to maximize performance and improve transmission range in the field. However, the single most important factor in transmit range (talk power) is your surrounding environment. These radios are "line of sight" radios and as such, transmission range is influenced by the degree to which you can "see" the other communicating party. Large concrete structures and heavy foliage or transmission from inside a building or vehicle will reduce your talk power. · Medium range: large buildings or trees blocking your line of sight. 13 RING FUNCTION ` Smart-Ring 7 The ring function has an answer back feature. This allows you to confirm whether or not a call has reached the receiving party even if the operator is temporarily away from the transceiver.
