Notice
The antenna will affect working distance, be sure to protect it and avoid any
man-made damage;
Working distance will be affected by surround environment, make sure the
background is open with no interference, and turn off the device’s WIFI during
usage;
RF strength is advised to set to ‘Low’ for short working-distance request, which
can help decrease power consumption and increase power duration;
While working with smartphone, one must purchase the TRS-TRRS audio cable
adapter separately;
Take notice of the batteries’ ‘positive and negative poles’ to avoid reverse,
otherwise the product maybe damaged;
Keep the product in dry environment;
Don’t expose the product or work with it in Rain to avoid short-circuit;
