Adjustment Item
Description
Counterclockwise 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 Volume
Receive Assist
The lock voltage of VCO (Receive) is adjusted.
This item must be adjusted before all adjustment items for receiver section are adjusted.
This item can be adjusted only in PC Test Mode.
Transmit Assist
The lock voltage of VCO (Transmit) is adjusted.
This item must be adjusted before all adjustment items for transmitter section are adjusted.
This item can be adjusted only in PC Test Mode.
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
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/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 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.
Single Tone Deviation
The deviation of Single Tone used in “2-tone” is adjusted.
MSK Deviation
MSK tone deviation is adjusted.
CW ID Deviation
CW 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.)
Sensitivity 1
Band-Pass Filter is adjusted.
The performance of Receive Sensitivity is improved.
This item can be adjusted only in PC Test Mode.
Sensitivity 2
The gain of RF amplifi er is adjusted.
The performance of the interfering wave is improved.
This item can be adjusted only in PC Test Mode.
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.
Battery Warning Level
Battery Warning Level (LED blinking level) is adjusted.
Battery Warning Level minus 0.4V is the transmission inhibited level.
