F/S—FAILSAFE/HOLD SETTING
The Failsafe function may be used to set up
positions that the servos move to in the case of
radio interference. This function only works with
PCM receivers (FM receivers do not have the fail-
safe capability).
You may set either of two positions for each
channel: normal, where the servo maintains its last
commanded position, or Failsafe, where each servo
moves to a predetermined position. You may
choose either mode for each channel.
The PCM 1024Z system also provides you with
an advanced battery monitoring function that
warns you when the receiver battery has only a
little power remaining. In this case, the throttle is
moved to the defined failsafe position, or if one
was not defined, to a medium speed position. The
throttle may be released by operating a predefined
control on the transmitter (the default is throttle),
do not continue to fly — land as soon as possible.
Remember, if your throttle suddenly moves to a
position you did not command, land at once and
use the voltmeter function, with a 250 or 500 mA
load, to check your receiver battery. Quite a few
models have been saved from unnecessary crashes,
thanks to the battery failsafe function.
Failsafe Setting Procedure
In the Model Menu, press the Failsafe key (F/S) to
get the Failsafe menu shown below.

Channel Selection Keys
Now you must decide which channels you want to go
to preset positions, and which you want to maintain their
last commanded position.
Use the Up-Arrow keys (F to M) to select the
desired channel. Now, press the F/S key to switch that
channel to the failsafe mode. Hold the stick, knob, or
slider at the desired position and press the SET (O)
key. The chosen servo command is now displayed in
percent underneath the selected channel buttons.
If you wish to reset the channel to the normal (hold)
function, press the NOR (Q) key. If you desire the
failsafe function later, the last setting is remembered and
displayed when the F/S key is again activated.
If you want the Battery Failsafe function to move the
throttle to a defined position, be sure to set it before you
leave this menu.
Battery Failsafe Release Function
This function releases the throttle from is held posi-
tion after indicating that your receiver battery is low. You
did remember to set a throttle failsafe position, didn't
you? REMEMBER TO LAND AS SOON AS POSSIBLE.
Call the Battery Failsafe setting screen by pressing the
BFS (R) key while in the Failsafe menu. Now, you
may choose that moving the throttle resets the condition,
or select another stick or switch deactivates it.
To set a desired throttle release position, move the
throttle stick to the point at which you wish the failsafe
to be released (perhaps low throttle but a bit above idle).
Now press the SET (Q) button to set this position
(the position is displayed in percent).
If you want to use another function to switch off the
battery failsafe, either choose the desired stick motion, or
move to the switch setting menu by pressing SWT (O).
For more information on the switch setting menu, refer
to page 37.
When you are through setting all the desired channels,
press the END key (N ) to return to the Model Menu.
