Quick Frequency Setting and Waterfall
Quick Frequency Setting: Press the frequency indicator to go into the quick frequency setting page. Input the frequency quickly and then select the right unit.
Waterfall: Press the waterfall display to change the spectrum range.
Getting Started
Register
All machines are registered at the factory. No need to input serial numbers again. If needed, turn the volume encoder to change the value, short press the volume encoder to change position, and at last, long press the frequency encoder to confirm.
Reset
Long press both the volume encoder and the frequency encoder simultaneously to reset. All settings will restore to initial factory settings. The registered information will be kept.
Antenna
The antenna that comes with the machine is a 433MHz antenna. Select the WFM mode and set the frequency to 90~110MHz to enjoy WFM radio. If you need to receive AM or LSB radio, please purchase the appropriate antenna.
First Time to Use
Connect the antenna to the machine, select WFM mode, and set the frequency to 90MHz~110MHz. Enjoy your device.
