CAUTIONS Before using the transceiver, read all the constructions careful and ‘ completely. . SAVE THIS INSTRUCTION MANUAL — This instruction manual ; contains important safety and operating moonstruck for the*f 1C-2400A/E and NEVER connect the transceiver to an AC outlet. This will ruin the transceiver. NEVER connect 16 V. DC power to the transceiver. Check the source voltage before connecting the power cable, NEVER allow children to touch the transceiver during operation.
