Adjustment Item
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 High Transmit Power is adjusted.
Power
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 Maximum Deviation of Analog (Wide 5K/
(Analog Wide 5K/ Wide 4K/Narrow) is adjusted.
Wide 4K/Narrow) This item must be adjusted before all
adjustment items for tone deviations are
adjusted.

Adjustment Item
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 No adjustment is required.
Deviation
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 6.25kHz spacing
channel.
(In FCC rule, Analog mode or CWID is
required.)
Battery Warning Battery Warning Level (LED blinking
Level 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 "
Both "Low RSSI" and "High RSSI" must
High RSSI
be adjusted. (The curve data of RSSI
level is applied.)
Description
" is adjusted.
