The X9503 2.4 contains a Timer System with two timers. 
One is an integrated timer that keeps track of total 
transmitter-on time for the model and displays on the 
Main display. You can configure this as a Countdown 
timer or Stopwatch. This timer also appears on the Main 
display when active and can be started, stopped and 
reset from the Main display. It is a good idea to use the 
Countdown timer as a reminder that it is time to land so 
as not to run out of fuel. If using the Countdown timer, 
an Auto Start function is available that will start the timer 
when the throttle is raised over 20% the first time after the 
transmitter is turned on.
1. To configure the timer as a Countdown timer, highlight 
and select Timer in the FUNCTION LIST to obtain 
the Timer display. 
Highlight and select INH under TIMER then select 
DOWN-T. Use the Selector to set the countdown start 
time. Once the timer is set, TIM appears in the lower left 
corner of the Main display. Press the button next to TIM 
on the Main display to start and stop the timer. Press the 
button next to CLR to reset the time to the programmed 
value.
2. To Reset the Integrated Timer, highlight and select the 
time under INTEG-T. Push [CLR]=0:00 appears 
on the display. Press the CLR button to the left of the 
display to reset the integrated timer.
The Servo Monitor function displays each channel and 
shows the movement of channels when sticks, levers 
and switches are moved. It renames channels according 
to special assignments to assist in identifying what is 
moving. For instance, when 120 CCPM Swashplate Type 
is selected, the Servo Monitor displays CH-2, CH-3, and 
CH-6. It is a handy way to determine what channels are 
mixed with other channels and verify programming when 
the helicopter is not at hand. The Monitor function also 
displays the current value of all digital trims.
1. To access the Monitor function, highlight and select 
MONITOR in the FUNCTION LIST to obtain the 
Monitor display.
2. The default display (MONI) shows the settings of 
all digital trims. To view the Monitor display of all 
channels, highlight and select MONI. View the display 
while moving sticks, switches and levers to see the 
movements of various channels.
3. To view the Digital Trim values and Hover Pitch (HOV 
P) and Hover Throttle (HOV T) Lever values, Highlight 
MONI with the Selector and press. The word MONI 
changes to TRIM to show the trim values for these 
levers. To move back to the Channels display, press 
TRIM to return to MONI and the servo travel and 
output positions display once again.
Note: If you’ve selected any CCPM mixing, channel 
naming will vary.
3. If the Auto Start function is desired which starts the 
timer by the throttle stick, select INH next to STICK and 
select this to ACT. With this set to ACT, the Auto Start 
function will start the timer when the throttle stick is 
raised above 20%.
