Connect the bare end of the red wire to your power
supply's positive(+) terminal.
Connect the bare end of the black wire to your power
supply's negative(-) terminal.
Plug the power cord's connector into the POWER
jack on the back of your transceiver.
Note: The power cord's connector and the POWER
jack are polarized, so the connector plugs in only one
way.
Warning: Do not apply power to the transceiver if you have
not connected an antenna. Transmitting without an antenna
attached damages your transceiver.
