40 SPEKTRUM NX20 • TRANSMITTER INSTRUCTION MANUAL
EN
The NX20 Timer function allows you to program a countdown timer
or stop watch (count up timer) to display on the main screen. An
alarm sounds when the programmed time is reached. You can
program the timer to start using the assigned switch position or
automatically when throttle is raised above a programmed position.
Two internal timers are available that show run time for a specific
model displays on the Main Screen. A total system timer is also
available.

The telemetry menu is in both the system setup and the function
list so you can access the telemetry functions from either list.
You must power off the receiver and transmitter, then power them
both on to reset the telemetry data. You can reset min/max values
by pressing the CLEAR button.
WARNING: NEVER change Telemetry Settings when the
aircraft is powered on. There is a brief interruption in RF
output when exiting the Telemetry screen, and may cause a
“Hold” condition.
Telemetry
If you bind a forward programming capable receiver to your NX20,
the Forward Programming menu will appear in the Function List.
Think of the Forward Programming menu as a programming
interface for your connected receiver. The menu structure, options
and any changes made are done directly on the receiver, the
transmitter is only an interface. Each device may have different
menu structure and operate in a different manner than the next
forward programming device. The receiver must be powered on
and bound to be able to enter the forward programming menu.
