To test the signal of your 18M, raise the module 1m off the ground, and about 100 feet (30 meters) away from the remote. The signal strength should be between -35 and -45 on average. If operating mesh (5.0 or higher), make sure only one module is on at a time when performing signal tests. If your module performs much less, such as -55 or lower, then the module likely has a bad transceiver that requires replacement. In this case, additional testing will be requested by the COBRA support team to determine if there is a fault.
