Avoid sudden drops. The device may fail to work after strong shocks,
impacts, or excess stress.
Keep dry. The product isn’t water-proof. Malfunction, rust, and corrosion
may occur and go beyond repair if soaked in water or exposed to high

temperature changes such as the circumstance when taking the
transmitter and receiver out of a building with higher temperature to
outside in winter. Please put the transmitter and receiver in a handbag
or plastic bag beforehand.

field produced by devices such as radio transmitters leads to malfunc-
tion.
