14.F /S (FAIL SAFE

)

PROGRAM

The Fail Safe function automatically moves the servos to a predetermined position in the event that the signal between the transmitter and the receiver is interrupted, whether due to signal degradation or to low transmitter battery. Several different setting options are available. The Fail Safe function can be set to Hold the servos in the last position they were in when the signal was lost, or each of the servos can be set to move to a custom position when the signal is lost. For example, the throttle

servo moves to the Brake Side to engage the brakes and stop your model. If you're driving a gas- or glow-powered boat, the

Fail Safe function could be set to lower the throttle to idle and turn the rudder slightly left or right so that the boat will continue in slow circles.

In addition, a Receiver Battery Voltage Fail Safe function is available which allows you to set a custom voltage that the Receiver Battery Fail Safe function will Activate at. This is useful if you're using servos with a higher than normal current draw that might

run out of power before the receiver does.

IMPORTANT: The Fail Safe function will NOT OPERATE if the receiver loses power. It will operate only if the transmitter and

receiver signal is interrupted or if the transmitter loses power.

Setting the Fail Safe:

Fail Safe settings can be programmed for each of the four channels individually. In addition, Fail Safe settings are model-specific, meaning you can have different Fail Safe settings for each Model in memory. Three Fail Safe options are available for each channel as described below:

FREE - Fail Safe is disabled for this channel. Servos can move freely when the signal is lost.

HOLD - When Fail Safe Activates, the servo will be held in the last position it was in when the signal was lost.

% (PERCENTAGE) - When Fail Safe Activates, the servo will travel to the programmed position when the signal is lost.

1) From the Top Screen, press the ENTER key to open the Programming Menu list.

2) Scroll UP or DOWN to highlight the F/S menu, then press the ENTER key. The F/S menu

will be displayed and [ST]:FREE will be highlighted.

3) Scroll UP or DOWN to highlight the desired channel you would like to change the Fail

Safe option for.

4) Press the ENTER key, then scroll UP or DOWN to choose the desired Fail Safe option for

that channel. If you choose to program a % value, see step 5 below.

F/S setting range is FREE, HOLD, or %. The default setting is FREE.

14.F /S (FAIL SAFE

)

PROGRAM

5) To program a Fail Safe percentage value, move the control the amount you want the

servo to move to when the Fail Safe function Activates and HOLD it in that position, then press and HOLD the ENTER key until an audible tone sounds. The percentage and direction the servo will travel will be displayed. For example, to set the Throttle Brake to engage when the Fail Safe function Activates, push the throttle trigger toward the Brake side the desired amount, HOLD the throttle trigger in that position, then press and HOLD

the ENTER key. The percentage value programmed will be indicated by two hash marks on the Servo Monitor.

6) Check to ensure your Fail Safe settings are working properly. Make sure that both the transmitter and receiver are turned ON, then, while someone is holding your model, turn the transmitter OFF. The servos should react correctly based on the

Fail Safe values chosen.

The Fail Safe settings will be retained even if the transmitter loses power or if the transmitter and receiver must be paired again.

When using an FH2 receiver with your transmitter, these Fail Safe features are not supported. In this case, the Fail Safe function must be programmed directly through the receiver. For more information, follow the Fail Safe Programming

instructions provided with your FH2 receiver.

Setting the Receiver Battery Voltage Fail Safe Function:

The Receiver Battery Voltage Fail Safe function is designed to alert you when your receiver battery requires recharging. This

ensures that the receiver battery's voltage doesn't drop so low that your servos aren't provided adequate voltage to operate optimally. When Activated, the throttle servo will move to the predetermined position you programmed in step 5 in the Setting the Fail Safe section above. If this occurs, recharge or replace your receiver batteries.

WARNING: This function is designed for use with glow- or gas-powered Models that use a separate receiver battery pack.

Do NOT use this function with an electric Model that uses the motor battery to power the servos and receiver.

PROGRAM

If FREE or HOLD is chosen for the Throttle channel, you cannot Activate the Receiver Battery Voltage Fail Safe function. A % value must be chosen for the Throttle channel to be able to program and use the Receiver Battery Fail Safe function.

The Receiver Battery Voltage Fail Safe function works only with FH3 and FH4T receivers.

1) Follow steps 1 through 5 in the Setting the Fail Safe section to program a Throttle Fail Safe percentage value.

2) From within the F/S menu, press the ENTER key, then scroll DOWN to highlight [B-F/S] OFF.

3) Press the ENTER key, then scroll UP or DOWN to choose the desired Receiver Battery

Fail Safe Voltage value. Many factors, such as the current draw of your servos and how many servos you're using, etc., will determine the value to use. A good starting point

would be 3.7V. If it appears your servos are slow or not producing adequate torque what

that Voltage value is reached, Increase the Voltage value.

F/S B-F/S setting range for FH4T receivers is OFF and 3.5V to 7.4V. F/S B-F/S setting range for FH3 receivers is OFF and

3.5V to 5.0V. The default setting is OFF regardless of the Modulation Type chosen.

15.LOGGER (TELEMETRY LOG

)

PROGRAM

The Telemetry Log function allows you to view a log of the Telemetry Data that is sent from the receiver to the transmitter. You

are able to view Telemetry Data for both Temperature outputs, the RPM output and the receiver's Voltage. This information can be used to track specific information about your model, such as cylinder head temperature if you're running a nitro-powered model or battery temperature if you're running an electric model and much more. The interval that Telemetry Data is read and stored can be adjusted so that Telemetry Data can be stored for up to 90 minutes of use. The Telemetry Log can store 120 different data entries at intervals ranging from 00.1 seconds to 45.9 seconds.

90478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDE

02.BIND (BINDING, MODULATION TYPE AND SERVO OPERATING MODE

)

SYSTEM

The Binding function allows you to Bind the transmitter and receiver pair. When new, it is necessary to pair the transmitter and receiver to prevent interference from transmitters operated by other users. This operation is referred to as Binding. Once the Binding process is complete, the setting is remembered even when the transmitter and receiver are turned OFF. Therefore,

this procedure usually only needs to be done once. In addition, the Modulation Type and Servo Operating Mode can also be changed to suit your specific setup.

Changing the Modulation Type:

The Modulation Type function allows you to choose the transmitter Modulation Type. The Modulation Type can be changed to match the receiver you're using. For example, if you wish to use an Airtronics 2.4GHz FH2 receiver with your transmitter,

you would need to change the Modulation Type to FH2 prior to Binding your transmitter and receiver. Modulation Type

is model-specific, meaning that you can have one model use FH4T Modulation and another model use FH2 Modulation, etc.

The Modulation Type must be chosen prior to Binding the transmitter and receiver. Make sure the Modulation Type you

choose matches the Modulation Type of the receiver you're using.

1) From within the SYSTEM menu, scroll UP or DOWN to highlight the BIND menu.

2) Press the ENTER key. The BIND menu will be displayed and [RF MODE]:FH4T will be

highlighted.

3) Press the ENTER key, then scroll UP or DOWN to select the desired Modulation Type, then press the ENTER key a second time. Set to (Modulation Type) NO/YES will be

displayed.

4) Scroll DOWN to highlight YES, then press the ENTER key.

The following Modulation Type options are available:

FH2 - Select this Modulation Type when using an Airtronics 2.4GHz FH2 surface receiver.

FH3 - Select this Modulation Type when using an Airtronics 2.4GHz FH3 receiver.

FH4T - Select this Modulation Type when using an Airtronics 2.4GHz FH4T Telemetry receiver.

FH3F/FH4FT - These Modulation Types are NOT used in North America. They are typically used in France.

IMPORTANT: Not all BIND menu functions are supported by all Modulation Types. Only supported functions will be

displayed once a Modulation Type is chosen. For example, the FH2 Modulation Type does not support the ability to change

the Servo Operating Mode.

Changing the Channel Mode - FH2 Modulation Type Only:

When the FH2 Modulation Tyep is selected, you can choose to operate the transmitter in either 2-Channel Mode or 4-Channel Mode. This option is available ONLY when [RF MODE] FH2 is selected.

1) From within the BIND menu, scroll DOWN to highlight [CH]:4ch.

2) Press the ENTER key, then scroll UP or DOWN to choose the desired Channel Mode. Selecting 2CH will enable 2-channel operation (Steering and Throttle). Selecting 4CH

will enable 4-channel operation (Steering, Throttle, Auxiliary 1 and Auxiliary 2).

BIND CH setting range is 2CH and 4CH. The default setting is 4CH.

Changing the Servo Operating Mode:

The Servo Operating Mode function is used to optimize the radio control system to suit the type of servos you're using in your

model. For example, using the SHR setting with Digital servos will Increase the servo's response time, even above the manufacturer's stated specification. If you're using Airtronics SRG Digital servos, you can use the SSR setting for the fastest

response time. The combination of using Digital servos and using the correct Servo Operating Mode results in the ultimate feel

and response, making you feel more in control of your model than ever.

02.BIND (BINDING, MODULATION TYPE AND SERVO OPERATING MODE

)

SYSTEM

1) From within the BIND menu, scroll UP or DOWN to highlight the desired channel you would like to change the Servo Operating Mode for. Choose from either [ST]:NOR (Steering), [TH]:NOR (Throttle), [A1]:NOR (Auxiliary 1) or [A2]:NOR (Auxiliary 2).

2) Press the ENTER key, then scroll UP or DOWN to choose the desired Servo Operating

Mode option for that channel.

SERVO OPERATING MODE setting range is NOR, SHR and SSR. The default setting is NOR. SSR Operating Mode is not supported when the FH3 or FH3F Modulation Type is selected. No Servo Operating Modes are supported when the FH2 Modulation Type

is selected.

IMPORTANT INFORMATION ABOUT SERVO OPERATING MODES:

If you're using Analog servos in your model, DO NOT use SHR or SSR Servo Operating Mode for those channels. Use the NOR (Normal) Servo Operating Mode with Analog servos. Using SHR or SSR Servo Operating Mode with Analog servos can

result in poor performance or even damage to the servos or the receiver! In some cases, the servo may not operate at all.

Not all ESCs are compatible with SHR or SSR Servo Operating Modes. If your ESC does not operate correctly, change the

Servo Operating Mode to NOR (Normal) for that channel (or channels).

SHR and SSR Servo Operating Modes should only be used with Digital servos. While the SHR Servo Operating Mode can be used with any brand of Digital servo, the SSR Servo Operating Mode should ONLY be used with Airtronics SRG Digital servos.

Binding the Transmitter and Receiver:

To Bind the transmitter and receiver, please see the Transmitter and Receiver Binding section on page 16. Prior to Binding the

transmitter and receiver, make sure to choose the desired Modulation Type that matches the receiver you're using. Servo

Operating Mode can be changed prior to Binding the transmitter and receiver, or after the Binding process.

03.KEY ASSIGN (KEY ASSIGNMENTS

)

SYSTEM

The Key Assignments function allows you to assign different functions to each of the two Push-Button Switches, the four Trim Switches, the Dial Knob and the Auxiliary Lever. In addition, the ON/OFF behavior of some Push-Button Switch functions can

be changed. The Key Assignments function also allows you to change the Direction of Travel and the Trim Resolution of the four Trim Switches and the Rotary Dial. This allows you to fine-tune the movement of the servos when the Trim Switches are pressed and the Rotary Dial is turned.

Switch Trm1, Trm2, Trm3 or Trm4. A list of functions that can be assigned to the Trim Switches is shown in the table above and on the previous page.

Changing the Trim Switch Step Value:

The Step function allows you to adjust how far the servos travel when the Trim Switches are pressed. You can increase the

Trim Resolution by decreasing the Step value, so that the servos travel less when you press the Trim Switches. This makes it possible to fine-tune servo movement extremely accurately.

Alternately, you could decrease the Trim Resolution by increasing the Step values, so that the servos travel more when you press the Trim Switches. This setting may not be as accurate, although it allows you to command large amounts of servo travel at a time.

1) From within the TRIM menu, scroll UP or DOWN to highlight the Step value you would

like to change for either TRM1, TRM2, TRM3 or TRM4.

2) Press the ENTER key, then scroll UP or DOWN to choose the desired Step value for Trim

Switch Trm1, Trm2, Trm3 or Trm4.

TRIM STEP setting range is 1 to 100. The default setting for TRM1 is 5, for TRM2 is 5, for TRM3 is 1 and for TRM4 is 1. The Step value is a percentage of servo travel.

Changing the Auxiliary Lever Function:

In general, the Auxiliary Lever is used to control Auxiliary 1 Channel 3 or Auxiliary 2 Channel 4. Adjusting the High and Low

Tweak values determines how far and in which direction the Auxiliary servo travels when the Auxiliary Lever is moved Up and

Down. For example, if you assign AUX2 to the Auxiliary Lever and adjust the Tweak values to +50 and -50, the Auxiliary 2 servo

will be centered when the Auxiliary Lever is centered and will travel 50% in one direction when the Auxiliary Lever is moved Up and travel 50% in the other direction when the Auxiliary Lever is moved Down. This allows you to use the Auxiliary Lever like a 2- or 3-position switch.

In addition, the Auxiliary Lever can be used to control the same parameter functions as the Trim Switches and the Rotary Dial. For example, if you assign TRIM-ST and adjust the Tweak values to +100 and -100, the Auxiliary Lever will control Steering channel Trim. The direction and amount the Trim moves when you move the Auxiliary Lever Up or Down is dependent on the Positive and Negative Tweak values.

To control either the Auxiliary 1 or the Auxiliary 2 servos using the Auxiliary Lever, the Auxiliary Type in the AUX TYPE menu must be either STEP AUX or POINT AUX. For more information, see the Auxiliary Type section on pages 59 and 60.

When you use the Auxiliary Lever to control a function, such as Steering Dual Rate or Exponential, the change in values will not be displayed in a pop-up window like they

are when you use the Trim Switches or the Rotary Dial to make the same changes. Instead, the current position of the Auxiliary Lever is displayed on the Top Screen.

1) From within the KEY ASSIGN menu, scroll UP or DOWN to highlight LEVER.

2) Press the ENTER key. The LEVER menu will be displayed and FUNCTION AUX2 will be

highlighted.

3) Press the ENTER key, then scroll UP or DOWN to choose the desired function for the

Auxiliary Lever. A list of functions that can be assigned to the Auxiliary Lever is shown in the table on pages 55 and 56.

Changing the High and Low Tweak Values:

The High and Low Tweak values determine the direction and amount of Auxiliary 1 or Auxiliary 2 servo travel. In addition, the High and Low Tweak values determine the direction and amount of parameter function changes, such as Steering Trim or the

Anti-Lock Braking Point percentage value.

1) From within the LEVER menu, scroll DOWN to highlight TWEAK(H) +100.

2) Press the ENTER key, then scroll UP or DOWN to choose the desired High Side Tweak

value. Increasing the Tweak value will increase servo travel in the High Side direction and decreasing the Tweak value will decrease servo travel in the High Side direction. Using a negative value will change the direction of servo travel.

LEVER TWEAK(H) setting range is -100 to +100. The default setting is +100.

3) Scroll DOWN to highlight TWEAK(L) -100.

4) Press the ENTER key, then scroll UP or DOWN to choose the desired Low Side Tweak

value. Decreasing the Tweak value will increase servo travel in the Low Side direction and increasing the Tweak value will decrease servo travel in the Low Side direction. Using a positive value will change the direction of servo travel.

LEVER TWEAK(L) setting range is -100 to +100. The default setting is -100.
