2.13 Frequencry Space and Frequencry Channel Submenu
The
10 Freq Space
and
11 Freq Channel
submenus are associated and related to the RF Channel Settings.
The
10 Freq Space
sub-menu sets Frequencry Space, i.e. the channel interval value, with setting range from
0 to 255 in kHz unit. The
11 Freq Channel
submenu sets the Frequencry Channel, i.e. the Channel signal,
with setting range from 0 to 255. The transceiver frequency offset can be calculated through the formula
showned belowed
：
Frequencry Offset = Frequencry_

This Frequency Offset is the initial frequency set in the "3 Frequencry Band". Since these two Settings are up
to 255, the maximum Frequencry Offset can achieve in range from 0MHz to 65MHz with unit of kHz. For
example, if the target frequency is 433.92MHz, then you can set the starting frequency to 433000kHz in the "3
Frequencry Band", and Frequencry Space value to 92, Frequencry Channel to 1
Select the 10 Freq Space or 11 Freq Channel and press K5 to enter the submenu, as shown in Figure 2-14 or
Figure 2-15.
