Battery Fail Safe (Receiver Battery Voltage Alarm) - AIRTRONICS SD-10G Operating Manual

SYSTEM MENU
Using the Fail Safe Function with FHSS-1 Receivers
If you are using the SD-10G transmitter with an FHSS-1 receiver, the Fail Safe setup procedures described previously do not
apply. Use the procedures described below to utilize the Fail Safe function with your FHSS-1 receiver.
Programmable Fail Safe is available on channels 1 through 4 only.
1) Drop the throttle control stick all the way back to the Low Throttle position, then turn the transmitter ON.
2) Turn the receiver ON. The Bind LED on the receiver should illuminate solid blue, indicating that the transmitter and receiver
are paired, then move the transmitter control sticks to verify that the servos are operating.
The Fail Safe settings will be erased if you re-bind the transmitter/receiver pair. If you bind the same transmitter/receiver
pair you MUST repeat these procedures to setup the Fail Safe function again.
3) Move the transmitter control sticks to the desired Fail Safe position. While holding the transmitter control sticks in those
positions (generally throttle at idle and a minimal amount of elevator and/or aileron), press and hold the Bind Button on the
receiver. After ~2 seconds, the Bind LED will begin to blink slowly. Continue holding the Bind Button until the Bind LED begins
to blink rapidly (~2 more seconds). Once the Bind LED begins to blink rapidly, release the Bind Button.
4) Turn the transmitter OFF to test Fail Safe operation. The servos should move to the positions that you set in step 3.

The Battery Fail Safe function allows you to set a custom receiver voltage, that when reached, will provide feedback to you by
quickly cycling the throttle servo up and down in 1 minute intervals to indicate that the receiver battery has reached the programmed
Battery Fail Safe voltage. This feedback will help prevent you from flying too long and losing receiver battery power.
The Battery Fail Safe function is not supported when used with FHSS-1 receivers.
Activating Battery Fail Safe
1) Press the Navigation Pad 56 to highlight BATTERY FAIL SAFE, then
press the ENTER key to display the BATTERY FAIL SAFE menu. The
cursor will default to >INH.
2) Press the YES/+ key to Activate the Battery Fail Safe function. ACT will
be displayed.
Adjusting Battery Fail Safe Voltage
1) Press the Navigation Pad 6 to highlight VOLT>4.2V, then press the
YES/+ or NO/- keys to increase or decrease the receiver voltage at
which the Battery Fail Safe Alarm will Activate.
VOLT setting range is 3.8V to 4.6V. The default setting is 4.2V.
Use the table below to help you decide at what voltage to set the Battery Fail Safe to. The voltage should be set so that
under no circumstances can the receiver battery be allowed to drop below its safe discharge level.
BATTERY TYPE
4 Cell Ni-Cd 4.8 Volt
5 Cell Ni-Cd 6.0 Volt
4 Cell Ni-MH 4.8 Volt
5 Cell Ni-MH 6.0 Volt
2 Cell Li-Po with 6.0 Volt Regulator
RECOMMENDED VOLTAGE
3.8 Volts
4.6 Volts
4.0 Volts
4.6 Volts
4.6 Volts

IMPORTANT When the receiver battery voltage
drops to the programmed voltage setting, the
throttle servo will quickly cycle up and down in
1 minute intervals. The Bind LED on the receiver
will also illuminate RED. When this occurs, we
strongly suggest you land as soon as possible
and recharge your receiver battery.
