Connecting External Devices; Connection To A Personal Computer - Yaesu DR-2X Operating Manual

Connection for DR-2XE (European and Australian versions)
Follow the outline in the illustration regarding the proper connection for the required External Power Supply.
The DC power connector for the DR-2XE must only be connected to a DC source providing 13.8V DC (±15 %),
and capable of at least 10A of current.
Always observe proper polarity when making DC connection.
Make sure to switch OFF the power of the external power source before connecting.
1 Insert the connector of the provided DC power cord into the DC IN jack at the rear of the repeater.

The external power source should be installed near the equipment and should be easily accessible.
Permanent damage can result when improper supply voltage, or reverse-polarity voltage, is applied to the DR-2XE.
The Limited Warranty on this radio does not cover damage caused by application of AC voltage, reverse polarity
DC, or DC voltage outside the specified range of 13.8 V ±15 %. When replacing fuses, be certain to use a fuse of
the proper rating. The DR-2XE requires a 15A blade fuse.
