Normal Display Screen

When the power switch is turned on, the LCD screen will read as shown below. This screen

is referred to as the Normal Display.

Note: If any of the electronic trim buttons are moved while in this screen, the screen

will automatically change to display the trim in use. This is called the Direct Trim

Mode. For more information on the feature, please see page 8 of this manual.

Low Battery Screen/Lithium Battery Backup

When the voltage of the eight “AA” batteries drops below 9.0 volts, the DX2.0’s display

screen will alternate between the Normal (see above) and Low Battery screen (BAT),

and a continuous beeping will occur, indicating that the batteries need to be replaced

before further use. The Low Battery screen is active during any operating modes.

Lithium Battery

Your DX2.0 radio system is equipped with a ﬁve-year lithium battery backup system.

This system is designed to protect and retain all radio programming in the event that

the transmitter batteries drop below the required 9.0 volts, or the transmitter battery case

is removed during battery changes. If after ﬁve years it becomes necessary to replace the

lithium battery, return your system to the Horizon Service Center for repair

(see address, page 29).

Memory Backup Screen

If the Memory Backup screen appears, this indicates the possibility of a ROM problem or the

lithium battery is dead. If you switch the power off and on again, and the transmitter is in the

default mode with all data lost, it is strongly suggested that the DX2.0 transmitter be returned

to the Horizon Service Center for servicing (see Warranty Information, page 29).
