OFNA Micro Fail Safe Unit - #91002 - Install & Setup

** FITS MOST IF NOT ALL U.S. R/C RADIOS **
The OFNA Fail Safe unit is used to protect your RC car from loss of control due to:

  • Weak radio signal
  • Low radio batteries
  • Radio interference of any kind
  • Another radio on the same channel
  • Low receiver car battery

The Fuzzy Logic CPU operates on 3.8 to 6.0 volts DC from your receiver battery pack.
Warning
- If receiver is dead or removed or car battery is switched off, THE FAIL SAFE UNIT WILL NOT FUNCTION, nor provide any RC control protection. **

Installation:
1) Connect the unit between your receiver and throttle servo. But before applying power double-check wiring color code to ensure correct polarity.
2) Locate unit in battery box or holder. It is best to keep dirt or water away from unit. Also, secure unit so it is not loose or allowed to wiggle freely on the lead wires.
3) To setup the unit, turn on the radio transmitter and car receiver. You should see the throttle and steering servo's operate normally. Also, the fail safe “red” light will be flashing quickly. If solid red, you may have radio problem or not turned ON.
4) With radio transmitter on, push throttle trigger to full brake and hold, not full throttle. Then, with a pin, push the Set Position button on the fail safe unit. You should feel a one click and a flashing red light indication. For a few seconds, the red led will flash quickly then pause, this pause indicates the fail safe is set to your brake trigger position.

The unit is now set. To check, turn off radio transmitter. Note the throttle servo will immediately move to the brake position set, in this case FULL. Also, the red light will be on. Solid Red means dangerous operation; flashing red means safe operation. With solid indication (Solid red), stop operation until interference or battery recharge is done.

IF YOU HAVE ANY QUESTIONS OR PROBLEMS, CALL OFNA TECHNICAL SUPPORT.
