RWARNING! NEVER connect the receiver via the OPC-254L to an AC outlet. This may pose a fire hazard or result in an elec-tric shock.RWARNING! NEVER operate the receiver while driving avehicle. Safe driving requires your full attention— anything less mayresult in an accident.NEVER connect the receiver to a power source of more than 14 VDC. This will damage the receiver.NEVER connect the receiver to a power source using reverse po-larity. This will damage the receiver.NEVER cut the DC power cable between the DC plug and fuseholder. If an incorrect connection is made after cutting, the receivermay be damaged.NEVER expose the receiver to rain, snow or any liquids. The re-ceiver may be damaged.NEVER operate or touch the receiver with wet hands. This mayresult in an electric shock or damage the receiver.NEVER place the receiver where normal operation of the vehiclemay be hindered or where it could cause bodily injury.NEVER let objects impede the operation of the cooling fan on therear panel.AVOID using or placing the receiver in direct sunlight or in areaswith temperatures below –10°C (+14°F) or above +60°C (+140°F).BE CAREFUL! The receiver will become hot when operating itcontinuously for long periods.AVOID setting the receiver in a place without adequate ventilation.Heat dissipation may be affected, and the receiver may be damaged.AVOID the use of chemical agents such as benzine or alcoholwhen cleaning, as they can damage the receiver’s surfaces.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.iiPRECAUTION

The receiver has 7 receive modes: LSBUSB, CW, AM, WFM, FM and digital modes. The mode se-lection is stored independently in each memory channels.Typically, AM mode is used for the AM broadcast stations(0.495–1.620 MHz) and air band (118–135.995 MHz), andWFM is used for FM broadcast stations (76–107.9 MHz).qPush [MODE•SCAN] to enter receive mode select mode.wRotate [DIAL] to select the desired mode.ePush any switch to exit receive mode select mode.[DIAL] [MODE•SCAN]While the band selection mode is selected, the digits below 100 kHz disappear.While 1 MHz tuning step is selected, the 1 MHz digit blinks.While 10 MHz tuning step is selected, the 10 MHz digit blinks.Push [VFO/MR•S.MW]Rotate [DIAL]

Scan resumes after the specified periodwhen the received signal disappears.•SCT-15/10/5 : Scan pauses for 15/10/5 sec. when thereceived signal disappears.•SCP-2 : Scan pauses on a signal until signal dis-appears, then resumes 2 sec. after thesignal disappears.DDProgram scan skip settingSets the program scan skip setting ON and OFF for VFOscan operation, such as programmed scan. (default: ON)This item appears when set mode is accessed from VFOmode only.DDScan skip area settingSets the pre-programmed scan skip area setting ON and OFFfor VFO scan operation, such as programmed scan.This item appears only when the scan skip area setting is pro-grammed by the clone ((p. 44)) and set mode is accessedfrom VFO mode.DDMemory name settingSets memory name setting from ON (appear) and OFF (notappear; default) for memory name appearance.This item appears when set mode is accessed from memorymode only.

459SET MODEDDIF shift frequency settingSelect the IF shift frequency up to ±25 steps in 1 step (50 Hzstep).This item appears when the receive mode is selected SSB orCW mode.DDSquelch delaySelects squelch delay from short and long to prevent re-peated opening and closing of the squelch during receptionof the same signal.•S : Short squelch delay.•L : Long squelch delay.DDANF settingTurns ANF (Automatic Notch Filter) function ON and OFF.The ANF function automatically attenuates up to 3 beat tones,tuning signals, etc. even if they are moving. The ANF func-tion can be used in SSB, AM, FM and WFM modes.☞This item appears when optional UT-106 is installed.DDNR settingSelects NR (Noise Reduction) level from 1 to 15 and OFF(Default).The NR function enhances desired signals in the presence ofnoise by using the DSP circuit. The amount of enhancementis adjustable.The NR level can result in audio signal masking. Set thenoise reduction level for maximum readability.☞This item appears when optional UT-106 is installed.Center position (default) Highest

4910 OTHER FUNCTIONS■Partial resetIf you want to initialize the operating conditions (VFO fre-quency, VFO settings, set mode contents) without clearingthe memory contents, a partial resetting function is availablefor the receiver left and right bands independently.➥While pushing desired band’s [VFO/MR•S.MW], turn thepower ON to partially reset the desired band (left or right).✔Hint!When pushing both [VFO/MR•S.MW] and turning the powerON, partially reset both bands at the same time.■ALL resetThe function display may occasionally display erroneous in-formation (e.g. when first applying power). This may becaused externally by static electricity or by other factors.If this problem occurs, turn power OFF. After waiting a fewseconds, turn power ON again. If the problem persists, per-form the following procedure.•Partial resetting is also available. See left for details.IMPORTANT!:Resetting the receiver CLEARS all memory informationand initializes all values in the receiver.➥While pushing both band’s [MHz•TS], turn the power ONto reset the CPU.[MHz•TS]While pushing both [MHz•TS], turn power ON.[MHz•TS]ATPOWER ONLeft band partial reset.Right band partial reset.ATPOWER ON
