Changing the Fail Safe Settings:
1) From within the SETUP menu, scroll UP or DOWN to highlight the F/S menu.
2) Press the ENTER key to open the F/S menu. ST > FREE will be highlighted.
3) Scroll UP or DOWN to highlight the desired channel you would like to change
the Fail Safe value for.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Fail Safe
value 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 for all channels is FREE.
5) To program a Fail Safe % value, move the transmitter control (e.g., Throttle
Trigger) the desired amount, then press and HOLD the ENTER key until an
audible Tone sounds. The direction and percentage the servo will travel will
be displayed. For example, to set the Brakes 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.
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.
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.
If using a Car Type that features two Steering channels or two Throttle channels (like a Rock Crawler) and you're programming
a Fail Safe % value, we suggest setting one of the Steering or Throttle channels to FREE and the other Steering or Throttle
channels to the desired Fail Safe % value. This will ensure one of the channels won't be fighting the other duplicate channel
should the Fail Safe function Activate.

B - F /S {RECEIVER BATTERY VOLTAGE FAIL SAFE}SETUP
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 servo(s) will move to the predetermined position that you programmed in step 5 in the
Changing
the Fail Safe Settings
section to indicate your receiver battery's voltage has dropped below the programmed Voltage value.
When used with an FH4 or FH4T receiver, the Receiver Battery Voltage Fail Safe function can be Activated for all four channels
independently. When used with an FH3 receiver, the Receiver Battery Voltage Fail Safe function can be Activated only for the
Throttle channel. The Receiver Battery Voltage Fail Safe function cannot be used with FH2 receivers.
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.
Choosing the Receiver Battery Voltage Value:
1) From within the SETUP menu, scroll UP or DOWN to highlight the B-F/S menu.

2) Press the ENTER key to open the B-F/S menu. VOLT (RX) > OFF will be
highlighted.
VOLT (RX) setting range for FH4 and FH4T receivers is OFF and 3.5V to 7.4V. VOLT (RX) setting range for FH3 receivers is
OFF and 3.5V to 5.0V. The default setting is OFF regardless of the Modulation Type chosen. Use with FH2 receivers is not
supported.
3) Press the ENTER key, then scroll UP or DOWN to choose the desired Receiver
Battery 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.
Activating the Receiver Battery Voltage Fail Safe Function:
The Receiver Battery Fail Safe function can be Activated for one or more channels, however, in most cases you will want
to Activate this function only for the Throttle channel. When Activated, the Throttle servo will move to the predetermined position
that you programmed in step 5 in the
Choosing Fail Safe Settings
section to indicate your receiver battery's voltage has dropped
below the programmed Voltage value. When this happens, stop using your Model and recharge the receiver battery.
A % value must be Selected to be able to Activate the Receiver Battery Voltage Fail Safe function. If FREE or HOLD is
Selected for any of the channels, you cannot Activate the Receiver Battery Voltage Fail Safe function.
1) From within the B-F/S menu, scroll UP or DOWN to highlight desired channel
number you want to Activate the Receiver Battery Voltage Fail Safe function for.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Battery
Fail Safe value, either ACT or INH.
3) Press the ENTER key, then repeat steps 1 and 2 to change any other desired
Battery Fail Safe values.
CH1, CH2, CH3 and CH4 setting range is INH and ACT. The default setting for all channels is INH.

LAP TIMER MENU {VIEW LAP TIMES AND CHOOSE LAP TIMER OPTIONS}SETUP
The Lap Timer function allows you to measure and record Lap Times for up to 250 Laps. The total number of Laps, the Current Lap
Time, the Best Lap Time and the Average Lap Time are all displayed. After the Lap Timer is Stopped, the Cumulative Time will be
displayed. Lap Times are displayed in the following format: 00':00".00 (Minutes : Seconds : 1/100th of a Second).
In addition to being able to view Lap Times, a Goal Time function is featured
that will sound when you reach your Goal Time. For example, you can set
the Goal Time value to the total time you would like to finish your race under.
If desired, a Pre-Alarm function can be programmed to Alert you to your
upcoming Goal Time.
Lap Times can be viewed within the LAP TIMER menu or on the TELEMETRY
screen ALL and LAP pages. In addition, a pop-up window will display when
the Lap Timer Starts and Stops, and each time a Lap Time is counted.
In the default configuration, placing the Lap Timer in Standby, Starting and
Stopping the Lap Timer, and counting Lap Times, is controlled using the Lap
Timer Switch (Push-Button Switch Sw3). In addition, if desired, the Throttle
Trigger can be used to Start the Lap Timer after it's been placed in Standby.
