Adjustment Item
Description
LCD Contrast
The contrast of LCD display can be
changed.
VCO Assist
The lock voltage of VCO is adjusted.
This item must be adjusted before
receiver and transmitter adjustment
items.
Frequency
Frequency 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.
RTC Correction
Real Time Clock is adjusted.
This item uses the internal clock.
(Any measurement equipment is not
required.)
High Transmit
Power
High Transmit Power is adjusted.
Mid Transmit Power Medium Transmit Power is adjusted.
Low Transmit Power Low Transmit Power is adjusted.
Ramp Offset
Adjust this item to the optimal Ramp
voltage.
Balance
The transmit modulation 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
(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.
High Deviation
NXDN/DMR high deviation is adjusted.
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
Deviation
The deviation of Single Tone used in “2-
tone” and “5-tone” is adjusted.
MSK Deviation
MSK deviation is adjusted.
CW ID 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.)
Battery Warning
Battery Warning Level (LED blinking
level) is adjusted.
Battery Warning Level minus 0.4V is the
transmission inhibited level.
IQ Phase
Correction of phase difference shift
between I and Q.
RSSI Reference
The minimum RSSI level for scan stop is
adjusted.
Squelch Open
The squelch level at level “1” is adjusted.
Squelch Tight
The squelch level at level “9” 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
