Hold the transmitter sticks in the position that you want the 
ser
vos to assume during signal loss conditions. Y
ou can 
determine fail-safe preset positions for the other channels by 
placing the potentiometers and switches in the positions that you 
want them to assume during inter
ference.
 
 
4.
 
With the sticks, switches and potentiometers in the fail-safe 
positions, touch the CLR key
. This will enter these locations as the 
fail-safe memor
y settings. A high pitched beep will indicate that 
this setting has been stored.

 confir
m that the input of data was successful, switch the 
transmitter OFF

not, repeat step 4 again.

 exit the Fail-Safe Function, press the UP and DN keys

Note:
 
These preset positions remain stored in the transmitter’
s 
memor
y until both the transmitter batter
y pack and the lithium 
back-up batter
y have been removed (or until data reset has been 
per
for
med). Therefore, you do not have to reset the fail-safe
 
each time you fly
. Should you want to re-adjust the fail-safe 
presets, access the Fail-Safe Function and adjust the presets as 
you have just done. The transmitter automatically recalls the 
settings for the last fail-safe adjustment.
 
 
 
ccessing the Fail-Safe/Hold Memory in S-PCM Modulation
 
Hold (S-PCM)
 
 
The Hold Function is automatically activated when the radio is 
tur
ned ON and in the S-PCM modulation.
 
 
This function stops (or holds) the ser
vos in the positions they were
in just prior to the interference. Therefore, your airplane 
maintains the position held immediately before the inter
ference 
was experienced. When a clear signal is restored, the Hold 
Function releases, and control of the airplane retur
ns to you.
 
 
1.
 
Place the transmitter power switch in the ON (upper)
 
position.
 
 
2.
 
While the power switch is in the ON position, press the UP
and DN keys simultaneously to access the Function Mode.
 
 
3.
 
Press either the UP or DN key until Fail-Safe appears in the 
left portion of your LCD.
 
 
Note:
 
If Fail-Safe does not appear on your LCD, it is because 
you are transmitting in PPM. Fail-Safe is not applicable in the 
PPM mode. Refer to the Modulation Mode Selection Section for 
more infor
mation.
 
 
Fail Safe/Hold Combination in S-PCM Modulation
 
 
The XP8
10
3 allows you to combine the hold and fail-safe presets 
for all eight (8) channels on the receiver — you can select fail- 
safe or hold independently for all channels on your aircraft. In 
other words, some channels will hold their last clear signal 
position, while others assume the preset position. Once the fail- 
safe has been activated by signal interruption (inter
ference), the 
transmitter automatically moves the ser
vos to a preset position. 
The predetermined ser
vo positions are set by you. In the S-PCM 
fail-safe, the time delay (the amount of time it takes, starting the 
moment the interference occurs, until the ser
vos assume the 
preset positions) is fixed at .
