RSSI value test standard for Cars and Boats Transmitter

If the remote-control distance of cars and ship transmitter is short, please refer to this instruction to test the transmitter. This instruction will introduce the test procedure of the transmitter RSSI value and the solution to the abnormal RSSI value. It is suitable for RC4GS, RC4GS V2, RC6GS and RC6GS V2 transmitter.

RSSI test method:
 1. Turn on the transmitter and power on the receiver at the same time, and then the transmitter and receiver will be connected (if not connected, you need to bind again), the signal mark in the red box in Figure 1 appears on the transmitter interface, indicating that the binding is successful.

2. Short press the Exit button twice to enter the return information interface, the top of the interface is the RSSI value (Figure 2).3. Make the receiver antenna and transmitter antenna parallel, single antenna and dual antenna receivers need to keep a distance from the transmitter(as shown below).

Observe the RSSI value of the return interface of the transmitter.

① receivers with one antenna, such as R6FG, R6F, R4FGM, R4F, R8EF, R8FM, R8SM:

When the distance between the transmitter and the receiver is 20 centimeters, it is normal that RSSI value is within the range of 0 to -30dBm. The closer the value is to 0, the stronger the signal is.

② receivers with dual antenna, such as R7FG, R8F:

When the distance between the transmitter and the receiver is 50 centimeters, it is normal that RSSI value is within the range of 0 to -30dBm. The closer the value is to 0, the stronger the signal is.

The range of RSSI value of RadioLink transmitters is from 0 to -99dBm. The larger the absolute value of the RSSI value is, the weaker the signal is. For example, the signal when the RSSI value is -90dBm is weaker than the signal when the RSSI value is -75dBm.

Abnormal Signal Strength Solution:

Check whether the antennas of the receiver and transmitter are damaged. Most signal strength degradation is caused by antenna damage. If it is damaged, the antenna needs to be replaced. If there is no damage, you can test the transmitter and receiver for malfunctions by replacing the receiver. If the equipment is faulty, the faulty equipment can be sent back for inspection and repair.
