To upgrade quality, any electrical or mechanical parts and
internal circuits are subject to change without notice or
obligation.
SERVICE CAUTION
NEVER connect the transceiver to a DC power supply
that uses more than the specified voltage. This will
ruin the transceiver.
DO NOT reverse the polarities of the power supply
when directly applying power to the transceiver/circuit.
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.

Be sure to include the following four points when
ordering replacement parts:

REPAIR NOTES
1. Make sure that the problem is internal before
disassembling the transceiver.
