The simple operation instructions are as follows:
1. Turn on: Press and hold the power switch for 2 seconds to turn on.
Shutdown: Press and hold the power switch for 2 seconds to shut down.
2. The knob in the upper right corner is used to adjust the volume and DSP bandwidth. Click this button to switch between volume adjustment and DSP bandwidth adjustment.
3. The second key in the upper right corner is frequency adjustment. When the underline at the bottom of the frequency is at the number, turn this knob to adjust the frequency value of the number. Tap the frequency value with your finger to adjust the position of the underline. Adjust the desired frequency. If the screen is blank, press the knob to light up the screen. Click the knob to switch between headphones and speakers.
4. Receiving mode conversion: press and hold the knob on the upper right for 3 seconds, then release it. There will be 5 receiving modes in the middle of the screen. Tap the selection with your finger to switch between USB LSB AM NFM WFM. If you don't want to switch, you can click the knob in the upper right corner again to exit.
5. Click BAND in the lower right corner of the screen, the internal frequency used before shutdown will be displayed. Tap with your finger to make a call directly. If it is the registered version, you can press and hold the frequency box and then hear a beep. The registered version has no storage function. Click BAND in the lower right corner of the screen to switch between page 3 and storage page. Click the knob in the upper right corner to exit.
6. Internal settings: press MENU in the lower left corner of the screen to enter, press HARD to enter EN1 Reverse and EN2 Reverse refers to whether the two knobs in the upper right corner are adjusted clockwise or counterclockwise, but this version cannot be saved without registration, and will It resets after shutdown, so no adjustments are required. The ANT option does not need to be adjusted. The internal default value is the input signal of the ANT terminal. When the PRE is receiving the shortwave frequency band, it is recommended to adjust it to OFF to make its internal filter work, so as to improve the anti-interference ability and enhance the received signal of the shortwave frequency. After the adjustment is complete, click the second option in the upper right corner to exit. Adjust the sound AUDIO according to your own preferences, and adjust the RF GAIN according to the received signal strength. The unregistered version is not very obvious.
1. HARD (hard) (hard) (setting):
EN1, EN2: The addition and subtraction directions of the two encoders are opposite.
V bat/power display: S standard, L low voltage.
SW ante / shortwave antenna options: 50ohm 50 ohm / Hi-z high impedance.
ATT attenuator: the same as the transceiver.
LNA / MIX, MIX GR: Do not open the functions that the machine (including the originals version) does not have, otherwise the gain and sensitivity will be greatly reduced!
RF GAIN / RF gain: Same as the transceiver, when the sensitivity is set to about 20, the sensitivity is the highest.
PREAMP/Preamplifier: Same as the transceiver. F correction/frequency correction: use as needed. Sm calibration / S meter calibration: use as needed.
Time setting: Long press HARD to input time setting, then press the volume encoder to increase or decrease the number, then press inward to switch. When you are done, press and hold the encoder and release it when it beeps.
2. Audio (audio): NB / spark noise Thes / start control value and Config / setting value; Set these two to 2, you can try it yourself. Note/Switch: Dis open/Ena off. AGC / automatic gain control.
AGC LIN / AGC peak: experimental adjustment.
Manual/manual control: experimental adjustment. AGC mode / AGC mode: relevant, fast, normal, slow, very slow.
EQ (Equalizer) EQ TYPE/Equalizer switch and selection: first click, then use the volume encoder to open and select; including light music, live, club, rock, bass, language...
WFM Stereo/FM Stereo: Headphones only.
NR / DSP noise reduction Thes / setting value: set according to hearing. SQL Thes / Set value. SQL switch.
