5.3

Frequency range and channel number

Model
E90-DTU(900SL33)
★ Note: In the same area, multiple sets of transmission stations are used to communicate one to one at the same time. It
is suggested that the channel interval be set above 2 MHz.
5.4

Transmit power level

Model
E90-DTU(900SL33)
★ Note: The lower the transmission power is, the closer the transmission distance is, but the working current will not
decrease in the same proportion, so it is recommended to use the maximum transmission power.
5.5

Air rate grade

Model
E90-DTU(900SL33)
Note: The higher the air speed setting, the faster the transmission rate, and the closer the transmission distance; so if
★
the rate meets the usage requirements, the lower the air speed, the better.

5.6 Current parameters

Model
E90-DTU(900SL33)
Note: It is recommended to retain more than 50% of the current margin when selecting the power supply, which is
★
conducive to the long-term and stable operation of the radio station.
