Adjustment item supplement
Adjustment Item
Description
LCD Contrast
The contrast of LCD display can be changed.
Receive 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.
RTC
Rea Time Clock (RTC) is adjusted.
This item uses the internal clock.
(Any measurement equipment is not required.)
Frequency
Frequency 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 Limit
The limit value of the High Transmit Power output is adjusted.
Low Transmit Power Limit
The limit value of the Low Transmit Power output is adjusted.
High Transmit Power
High Transmit Power is adjusted.
Low Transmit Power
Low Transmit Power is adjusted.
Balance
The 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 5k/Wide 4k/
Narrow)
Maximum Deviation of Analog (Wide 5k/Wide 4k/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 “CWID Deviation (NXDN Very
Narrow)” 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.
MSK Deviation
MSK tone deviation is adjusted.
CWID Deviation
CWID tone deviation is adjusted.
CWID is used to inform the others who is transmitting on a 6.25-kHz spacing channel.
(In FCC rule, Analog mode or CWID is required for each channel-spacing.)
RSSI Reference
The minimum RSSI level for scan stop is adjusted.
Open Squelch
The squelch level at level “5” is adjusted.
Low RSSI
RSSI display level “
“ is adjusted.
Both “Low RSSI” and “High RSSI” must be adjusted.
(The curve data of RSSI level is applied.)
High RSSI
Tight Squelch
The squelch level at level “9” is adjusted.
