Caution
Mandatory Procedures
In case of the High Response System (H.R.S) receiver R203HF, always use only the
following conditions:
Servo; 6V type Digital Servo only
Power supply; 6V Nicd battery
Transmitter setting; "HRS" mode
If the conditions are different, control is impossible.
And Fail Safe Unit (FSU1) is not available.
Warning
Operation Precautions
Prohibited Procedures
Do not operate two or more models
on the same frequency at the same
time.
Operating two or more models at same time on the
same frequency will cause interference and loss of
control of both models.
AM, FM (PPM) PCM and HRS are different
methods of modulation. Nonetheless the same frequency can not be used at the same point in time,
regardless of the signal format.
Do not operate outdoors on rainy
days , run through puddles of water or
when visibility is limited.
Should any type of moisture (water or snow) enter any
component of the system, erratic opreation and loss
of control may occur.
Mandatory Procedures
Extend the transmitter antenna to its
full length.
If the transmitter antenna is not fully extended the operating range of the radio will be reduced.
Check the transmitter antenna to be
sure it is not loose.
If the transmitter antenna works loose, or is disconnected while the model is running signal transmission
will be lost. This will cause you to lose control of the
model.
Do not operate in the following
places.
-Near other sites where other radio control
activity may occur.
-Near people or roads.
-On any pond when boats are present.
-Near high tension power lines or communication broadcasting antennas.
Interference could cause loss of control. Improper installation of your Radio Control System in your model
could result in serious injury.
Do not operate this R/C system when
you are tired, not feeling well or under
the influence of alcohol or drugs.
Your judgment is impaired and could result in a dangerous situation that may cause serious injury to yourself as well as others.
For Your Safety As Well As That Of Others
Always perform an operating range
check prior to use.
Problems with the radio control system as well as improper installation in a model could cause loss of control.
(Simple range test method)
Have a friend hold the model, or clamp it down or
place it where the wheels or prop can not come in
contact with any object. Walk away and check to
see if the servos follow the movement of the controls on the transmitter. Should you notice any abnormal operation, Do not operate the model. Also
check to be sure the model memory matches the
model in use.
7
Caution
Prohibited Procedures
Do not touch the engine, motor, speed control or any part of
the model that will generate heat while the model is operating
or immediately after its use.
For Your Safety As Well As That Of Others
These parts may be very hot and can cause serious burns.
Mandatory Procedures
(Turning on the power switches)
Always check the throttle trigger on the transmitter to be sure it is at the neutral position.
1. Turn on the transmitter power switch.
2. Turn on the receiver or speed control power switch.
(Turning off the power switches)
When making adjustments to
the model do so with the engine not running or the motor
disconnected.
You may unexpectedly lose control and
create a dangerous situation.
Always be sure the engine is not running or the motor is stopped.
1. Turn off the receiver or speed control power switch.
2. Then turn off the transmitter power switch.
If the power switches are turned off in the opposite order the
model may unexpectedly run out of control and cause a very
dangerous situation.
When operating your model
always display a frequency
flag on your transmitter antenna.
(Fail safe function) ---H.R.S mode only
Before running (cruising), check the fail safe function.
Check Method;
Before starting the engine, check the fail safe function as follows:
1) Turn on the transmitter and receiver power switches.
2) Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail
safe data to the receiver every minute.)
3) Check if the fail safe function moves the servos to the preset position when reception fails.
The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when
reception fails. However, if set to a dangerous position, it has the opposite effect.
Setting example: Throttle idle or brake position
