•

Ensure that a basic RF link exists between a base station and a remote unit.

•

Test the basic link with Link Monitor and adjust Tx power level.

•

Perform some simple network tests.

This test ensures that a basic RF link exists between a base station and a remote unit.

Tip: First configure one unit as a base station, and then use it to test all the remote units.

Ensure that the other unit(s) are configured as remote units with the center frequency the same as the 
base station. See 

The quality of your digital data transmission depends greatly on the quality of your RF 

link. Always try to establish a high-quality RF link first. A high-quality RF link will 

result in high-quality data transmissions and a low BER. A low-quality RF link will result 

in low-quality data transmissions and a high bit error rate (BER). Digital data can always 

be sent across a high-quality RF link. If the RF link is of poor quality, data either cannot 

be sent at all or will contain too many errors to be useful..
