Display Screens
Normal Display
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 21
of this manual.
Low Battery/Lithium Battery Backup
When the voltage of the 8 "AA" batteries drops below
9.0V, the XR2i's display screen will alternate between
the Normal and Low-Battery screen (BAT) and a con-
tinuous 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 XR2i 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 28).
Memory Backup
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, but the transmitter is in the default mode with
all data lost, it is strongly suggested that the XR2i
transmitter be returned to the Horizon Service Center
for servicing (see Warranty Information page 27).
