NX-300(S)37Adjustment item supplementAdjustment Item DescriptionCounterclockwise Volume “Counterclockwise Volume” is adjusted at the minimum volume position.“Clockwise Volume” is adjusted at the maximum volume position.These adjustments can correct the volume variation.Both “Counterclockwise Volume” and “Clockwise Volume” must be adjusted.(The curve data of volume is applied.)Clockwise VolumeReceive Assist The lock voltage of VCO (Receive) is adjusted.This item must be adjusted before all adjustment items for receiver section are adjusted.Transmit Assist The lock voltage of VCO (Transmit) is adjusted.This item must be adjusted before all adjustment items for transmitter section are adjusted.FrequencyFrequency stability is adjusted under receiving condition with SSG.The SSG needs 0.001ppm accuracy so please use a standard oscillator if necessary.This item can be adjusted only in PC Test Mode so that the adjustment value is not changed easily.High Transmit Power High Transmit Power is adjusted.Low Transmit Power Low Transmit Power is adjusted.BalanceThe transmit audio frequency response is adjusted.This item is adjusted so that the deviation of 2kHz becomes the same deviation of 20Hz.This item must be adjusted before all adjustment items for deviations are adjusted.Maximum Deviation(NXDN Narrow/Very Narrow) Maximum Deviation of NXDN (Narrow/Very Narrow) is adjusted.Maximum Deviation(Analog Wide/Narrow)Maximum Deviation of Analog (Wide/Narrow) is adjusted.This item must be adjusted before all adjustment items for tone deviations are adjusted.Note: “Maximum Deviation (Analog Narrow)” must be adjusted before “CW ID Deviation (NXDN VeryNarrow)” is adjusted.QT Deviation QT tone deviation is adjusted.DQT Deviation DQT tone deviation is adjusted.LTR Deviation LTR tone deviation is adjusted.DTMF Deviation DTMF tone deviation is adjusted.Single Tone Deviation The deviation of Single Tone used in “2-tone” is adjusted.MSK Deviation MSK tone deviation is adjusted.CW ID DeviationCW ID tone deviation is adjusted.CW ID is used to inform the others who is transmitting on a 6.25-kHz spacing channel.(In FCC rule, Analog mode or CW ID is required for each channel-spacing.)VOX 1 VOX sensitivity at “VOX 1” is adjusted.VOX 10 VOX sensitivity at “VOX 10” is adjusted.Sensitivity 1 Notch fi lter is adjusted.The performance of Receive Spurious Response is improved.Sensitivity 2 Band-Pass Filter is adjusted.The performance of Receive Sensitivity is improved.RSSI Reference The minimum RSSI level for scan stop is adjusted.Open Squelch The squelch level at level “5” is adjusted.Low RSSI Both “Low RSSI” and “High RSSI” must be adjusted.(The curve data of RSSI level is applied.)High RSSITight Squelch The squelch level at level “9” is adjusted.Battery Warning Level Battery Warning Level (LED blinking level) is adjusted.Battery Warning Level minus 0.4V is the transmission inhibited level.ADJUSTMENT
