Adjustment Item
Description
Receive Assist
The lock voltage of VCO (Receive) is ad-
justed.
This item must be adjusted before all ad-
justment items for receiver section are
adjusted.
Transmit Assist
The lock voltage of VCO (Transmit) is ad-
justed.
This item must be adjusted before all ad-
justment items for transmitter section are
adjusted.
Frequency
Frequency is adjusted under receiving
condition with SSG.
The SSG needs 0.001ppm accuracy so
please use a standard oscillator if neces-
sary.
This item can be adjusted only in PC Test
Mode so that the adjustment value is not
changed easily.
Ramp Offset
Adjust this item to the optimal Ramp volt-
age.
High Transmit
Power
High Transmit Power is adjusted.
Medium Transmit
Power
Medium Transmit Power is adjusted.
Low Transmit
Power
Low Transmit Power is adjusted.
Balance
The transmit modulation frequency re-
sponse is adjusted.
This item is adjusted so that the deviation
of 6kHz becomes the 96% deviation of
20Hz.
This item must be adjusted before all ad-
justment items for deviations are adjust-
ed.
Maximum Deviation
(P25/NXDN)
Maximum Deviation of P25/NXDN is ad-
justed.
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 ad-
justment items for tone deviations are ad-
justed.
QT Deviation
QT deviation is adjusted.
DQT Deviation
DQT deviation is adjusted.
LTR Deviation
LTR deviation is adjusted.
DTMF Deviation
DTMF deviation is adjusted.
Single Tone Devia-
tion
The deviation of Single Tone used in “2-
tone” 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 chan-
nel. (In FCC rule, Analog mode or CWID
is required for each channel-spacing.)
Sensitivity 1
Band-Pass Filter is adjusted.
The performance of Receive Sensitivity is
improved.
