There is a little known feature of the XLR Sniffer/Sender which, when the battery is reversed, shows the LEDs in the opposite color. This can be useful when the green is difficult to see or red is a better color of the situation. Simply reverse the battery to get the desired color for reporting.
If you see any orange LED's that means your unit has a orange led swap with the traditional red. Here is a link to an updated color code chart for the orange LED's. If you'd like to exchange your unit for a standard red LED sniffer please send an email to [email protected].
