at the time of publication.
NEVER
connect the transceiver to an AC outlet or to a DC
power supply that uses more than the specified voltage.
This will ruin the transceiver.
DO NOT
expose the transceiver to rain, snow or any liquids.
DO NOT
reverse the polarities of the power supply when
connecting the transceiver.
DO NOT
apply an RF signal of more than 20 dBm (100 mW) to
the antenna connector. This could damage the transceiver’s
front-end.
To upgrade quality, any electrical or mechanical parts
and internal circuits are subject to change without notice
