This service manual describes the latest technical informa-
tion for the ID-51A/ID-51E VHF/UHF TRANSCEIVER, at the time of
publication.
NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than the specifi ed voltage. This
will ruin the transceiver.
DO NOT reverse the polarities of the power supply when con-
necting 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
or obligation.
