Range Testing Your R/C System - FUTABA FMT-03 Instruction Manual

Range Testing Your R/C System

It is extremely important to range check your models prior to each flying session. This enables you
to ensure that everything is functioning as it should and to obtain maximum enjoyment from your time
flying. The FMT-03 transmitter incorporates a system that reduces its power output and allows you to
perform such a range check.
Range check mode
1. While pushing previously "U.menu/Mon" button.
2. FMT-03 Power ON.
U.menu/Mon
3. Scroll to "NO" and push RTN.
4. "RANGE CHECK" is chosen from
"SYSTEM MENU" and push RTN.
5. "YES" is chosen from "RANGE
CHECK" and push RTN.
During this mode, the RF power output is reduced
so the range test can be performed. In addition, when
this mode is activated the right LED on the front of the
transmitter starts blinking and the transmitter gives users
a warning with a beeping sound every 3 seconds.
The "Range check mode" continues for 90 seconds
and after that the power will return to the normal level.
To exit the "Range check mode" before the 90 seconds,
select the "EXIT" at the screen and touch the RTN button
again. This mode is available one time only so if you
need to re-use this function the transmitter power must
be cycled. NEVER start flying when the "Range check
mode" is active.
Should you require additional time to perform a range
check, highlight Restart before your time expires and
press the RTN button one time.
Range check procedure
1. With the "Range check mode" on, walk
away from the model while simultaneously
operating the controls. Have an assistant
stand by the model to confirm that all
controls are completely and correctly
operational. You should be able to walk
approximately 30-50 paces from the model
without losing control.
2. If everything operates correctly, return to
the model. Set the transmitter in a safe, yet
accessible, location so it will be within reach
after starting the engine or motor. Be certain
the throttle stick is in the low throttle position,
then start the engine or motor. Perform
another range check with your assistant
holding the aircraft with the engine running
at various speeds. If the servos jitter or move
inadvertently, there may be a problem. We
would strongly suggest you do not fly until the
source of the difficulty has been determined.
Look for loose servo connections or binding
pushrods. Also, be certain that the battery
has been fully charged.

WARNING
Do not fly in the range check mode.
*Since the range of the radio waves is short, if the model
is too far from the transmitter, control will be lost and the
model will crash.
