Spektrum SPM2020 DX2 - Manual (Page 14)

Lithium Battery
Your DX2 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 31).
Memory Backup Screen
If the Memory Backup screen appears, this indicates the possibility of a memory issue or
the lithium battery is dead. If you switch the power off and on again, and transmitter is in
the default mode with all data lost, it is suggested that the DX2 transmitter be returned to the
Horizon Service Center for servicing (see Warranty Information, page 31).
