Note: If your goggles have been previously used with other modules that have a very heavy current draw, your goggle power supply may have been overstressed. If so, we recommend that before installation, you check the health of your goggles by measuring your module power supply voltage with a single and simple video receiver module such as a NexWave plugged in. Before doing so, identify which module pin is the Vin (+5V) pin. (This is usually printed on the bottom of the module). You can use the antenna SMA threads as a ground for your meter. The voltage from this module pin to the SMA threads should measure between 4.8V to 4.55V with the goggle module switch in the “on” position. Note that the ClearView Goggle Receiver draws much less current than heavy draw modules.
