INSTRUCTION MANUALi208HVHF/UHF FM TRANSCEIVERThis device complies with Part 15 of the FCC rules. Operation is sub-ject to the following two conditions: (1) This device may not causeharmful interference, and (2) this device must accept any interferencereceived, including interference that may cause undesired operation.New2001IC-208H.qxd 03.2.26 20:00 Page 1 (1,1)

RWARNING RF EXPOSURE! This device emits RadioFrequency (RF) energy. Extreme caution should be observed whenoperating this device. If you have any questions regarding RF expo-sure and safety standards please refer to the Federal Communica-tions Commission Ofﬁce of Engineering and Technology’s report onEvaluating Compliance with FCC Guidelines for Human Radio fre-quency Electromagnetic Fields (OET Bulletin 65).RWARNING! NEVER connect the transceiver to an AC out-let. This may pose a ﬁre hazard or result in an electric shock.RWARNING! NEVER operate the transceiver while driving avehicle. Safe driving requires your full attention—anything less mayresult in an accident.NEVER connect the transceiver to a power source of more than16 V DC. This will damage the transceiver.NEVER connect the transceiver to a power source using reversepolarity. This will damage the transceiver.NEVER cut the DC power cable between the DC plug and fuseholder. If an incorrect connection is made after cutting, the transceivermay be damaged.NEVER expose the transceiver to rain, snow or any liquids. Thetransceiver may be damaged.NEVER operate or touch the transceiver with wet hands. This mayresult in an electric shock or damage the transceiver.NEVER place the transceiver where normal operation of the vehi-cle may be hindered or where it could cause bodily injury.NEVER let objects impede the operation of the cooling fan on therear panel.DO NOT push the PTT when not actually desiring to transmit.DO NOT allow children to play with any radio equipment contain-ing a transmitter.During mobile operation, DO NOT operate the transceiver with-out running the vehicle’s engine. When the transceiver’s power is ONand your vehicle’s engine is OFF, the vehicle’s battery will soon be-come exhausted.AVOID using or placing the transceiver in direct sunlight or inareas with temperatures below –10°C or above +60°C.BE CAREFUL! The transceiver will become hot when operat-ing it continuously for long periods.AVOID setting the transceiver in a place without adequate venti-lation. Heat dissipation may be affected, and the transceiver may bedamaged.AVOID the use of chemical agents such as benzine or alcoholwhen cleaning, as they can damage the transceiver’s surfaces.USE Icom microphones only (supplied or optional). Other manu-facturer’s microphones have different pin assignments and may dam-age the transceiver if attached.For U.S.A. onlyCAUTION: Changes or modiﬁcations to this device, not ex-pressly approved by Icom Inc., could void your authority tooperate this device under FCC regulations.iiNew2001PRECAUTIONIC-208H.qxd 03.2.26 20:00 Page ii (1,1)

7411OTHER FUNCTIONSNew200111DAdjusting the transmit signal output fromthe TNCWhen setting data transmission speed to 9600 bps, the datasignal coming from the TNC is applied exclusively to the in-ternal limiter circuitry to automatically maintain band width.NEVER apply data levels from the TNC of over 0.6 V p-p, oth-erwise the transceiver will not be able to maintain the bandwidth and may possibly interfere with other stations.1. When using a level meter or synchroscope, adjust theTX audio output level (DATA IN level) from the TNC asfollows.0.4 V p-p (0.2 V rms) : recommended level0.2 V p-p–0.5 V p-p (0.1–0.25 V rms) : acceptable level2. When NOT using a measuring device.qConnect the transceiver to a TNC.wEnter a test mode (“CAL”, etc.) on the TNC, then trans-mit some test data.eWhen the transceiver fails to transmit the test data ortransmits sporadically (TX indicator doesn’t appear orﬂashes):- Decrease the TNC output level until the transmit indi-cator lights continuously.When transmission is not successful even though theTX indicator lights continuously:- Increase the TNC output level.IC-208H.qxd 03.2.26 20:01 Page 74 (1,1)
