5712 REJECTING INTERFERENCENOISE BLANKERNoise Blanker was designed to reduce pulse noisesuch as that generated by automobile ignitions.Noise Blanker does not function in FM mode.Press [NB/ LEVEL] to toggle the Noise Blanker ONand OFF.• “NB” appears when the function is ON.You can further adjust the Noise blanker level from1 to 10. The default level is 6.Press [FUNC], [NB/ LEVEL], then turn the MULTI/ CHcontrol to adjust the noise blanker level.• “NB LEVEL” and the current level appear on thesub dot-matrix display.Note: Noise Blanker is available only for the main transceiver inSSB, CW, FSK, and AM modes.PRE-AMPLIFIERSwitching the Pre-amplifier OFF may help reduceinterference from adjacent frequencies.Press [PRE/ LOCK A] to toggle the Pre-amplifier ONand OFF.• “PRE” appears when the function is ON.The ON/OFF setting will be automatically stored inthe current band. Each time you select the sameband, the same setting will be automatically selected.The frequency range of each band is provided in thefollowing table (under “ATTENUATOR”).Note: If the same frequency (144 MHz or 430 (440) MHz) band isselected on both the main transceiver and the sub-receiver, thepre-amplifier can be switched ON or OFF for both receivers. Thisis because the main transceiver and sub-receiver share the sameantenna.ATTENUATORThe Attenuator reduces the level of received signals.This function is useful when there is stronginterference from adjacent frequencies.Press [ATT/ F LOCK] to toggle the Attenuator ONand OFF.• “ATT” appears when the function is ON.The ON/OFF setting will be automatically stored inthe current band. Each time you select the samefrequency band, the attenuator setting will beautomatically recalled.The frequency range of each band is shown below.sdnaBycneuqerF)zHM(reifilpma-erP)tluafeD(rotaunettA)tluafeD(5.2~30.0 FFO FFO1.4~5.2 FFO FFO5.7~1.4 FFO FFO5.01~5.7 NO FFO5.41~5.01 NO FFO5.81~5.41 NO FFO5.12~5.81 NO FFO5.52~5.12 NO FFO0.03~5.52 NO FFO0.06~0.03 NO FFO003~811 NO FFO215~003 NO FFO0031~0421 NOsyawlA FFOsyawlANote:uIf the same frequency (144 MHz or 430 (440) MHz) band isselected on both the main transceiver and the sub-receiver, theattenuator can be switched ON or OFF for both receivers.
