Charging the battery
Plug the Power cord into adaptor , Micro USB connected SF-401, The Led indicating:
*The RED Led is light - Charging
* The Green Led is light - Full
How to check Frequency measuring. See PIC.3
The transmitter near the frequency counter antenna , see the signal reception conditions is zone green, you can test. Please see Pic.3
cautions:
e.g. display 1800.000Mhz , The transmitter distance is too close to the frequency counter will affect the test results, , the signal bar is red .(see Pic.1)
e.g. display 0.000, , The transmitter distance is too far to the frequency counter and signal is weak ,will affect the test results, the signal bar is low .(see Pic.1)
How to check Frequency of Digital DMR Radio
Press[ F3 Digital] from Measuring screen mode See PIC.1
Note: Use Digital mode have 3 Decimal only
MENU funtion setting and save. See PIC.4
