Setting the Receiver Battery Voltage Fail Safe Function
The Receiver Battery Voltage Fail Safe function allows you to set a custom voltage that the Receiver Battery Voltage Fail
Safe function will Activate at. When your receiver battery voltage drops to the programmed voltage, the throttle servo will
move to the predetermined position you programmed in step 5 in the Setting the Fail Safe section on the previous page. If
If FREE or HOLD is chosen for the Throttle channel, you cannot Activate the Receiver Battery Voltage Fail Safe
The Receiver Battery Voltage Fail Safe function works only with FHSS-4T and FHSS-3 receivers. When using an
FHSS-2 receiver, these Fail Safe features are not supported. In this case, Fail Safe must be programmed through
1) Follow steps 1 through 5 in the Setting the Fail Safe section on the previous page
to program a Throttle Fail Safe percentage value.
2) From within the F/S menu, press the ENTER key, then scroll DOWN to highlight
3) Press the ENTER key, then scroll UP or DOWN to choose the desired Receiver
F/S B-F/S setting range is 3.5v to 7.4v. The default setting is OFF.
The receiver will operate down to 2.5 volts, however, the minimum operating voltage of most servos is higher than
that. The Receiver Battery Fail Safe Voltage should be set to a value that will allow all of your servos to operate.
The Telemetry Log function allows you to view a log of the Telemetry Data that is sent from the receiver to the transmit-
ter. 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. The interval that Telemetry Data is read and stored can be adjusted so that Telemetry

Starting and Stopping the Telemetry Log
The Telemetry Log function must be Started in order for the transmitter to read and store Telemetry Data from the re-
ceiver.
1) In the default configuration, Push-Button Switch Sw1 controls the Telemetry Log. To start the Telemetry Log, press
the Push-Button switch. LED1 (Blue) will flash, indicating the Telemetry Log is storing data. Telemetry Data is stored
for all four Telemetry functions, whether the Telemetry Sensors are hooked up or not.
Each time the Telemetry Log is started, any old Telemetry Data is automatically erased. In addition, the Telemetry
Log will stop automatically once the Telemetry Log is filled. The Telemetry Log can store 120 separate entries. If the
Log Interval is set to 00.1 seconds, the Telemetry Log can record for 12 seconds. If the Log Interval is set to 45.1 seconds,
If a Telemetry Sensor is not connected, default Telemetry Data for that input will be shown in the Telemetry Log.
