Display Screens
Normal Display Screen
When the power switch is turned on, the LCD screen will
read as shown here in the diagram. 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 19 of this manual.
Low Battery Screen/Lithium Battery
Backup
When the voltage of the eight AA batteries drops below 9.0
volts, the XR-2’s display screen will alternate between the
Normal (see above) and Low Battery screen (BATT) 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 of the three operating modes.
Lithium Battery
Your XR-2 radio system is equipped with a 5 year lithium
battery backup system. This system is designed to protect
and retain all radio programming in the event that the trans-
mitter 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 23).
Memory Backup Screen
If the Memory Backup screen appears, this indicates that any
programming changes made since the last time the system
was turned on must be saved by pressing the MODE and
CHANNEL buttons at the same time. If you do not save, the
recent programming changes will be lost. If this screen
appears for a second time, it is suggested that the XR-2
transmitter be returned to the Horizon Service Center for ser-
vicing (see Warranty Information, page 23).
