9 POWERING UP
Before switching the power on, check all the necessary connections: Earth, Antenna, Transceiver, PTT. Make
sure the 2 switches on the front panel are in the positions: OFF, STBY.
Switch now the mains power ON (The power switch to ON position). The "soft start" system will take about 5
seconds to fully turn the power on. SWR light will turn on briefly, then off. Wait for the DX-3SP to warm up,
until the READY light turns on.
This takes about 2 - 3 minutes.
WARNING !
WHEN YOU SWITCH THE POWER ON, YOU MUST HEAR AIR FLOW NOISE.
IF THERE IS NO AIR FLOW NOISE, SWITCH THE POWER OFF IMMEDIATELY
AND CONTACT YOUR SUPPLIER
