Can I adjust the shock sensor sensitivity?
Yes, locate the control unit and turn the shock sensor adjustment screw with a small screwdriver. Clockwise increases sensitivity, counterclockwise decreases.
What should I do if the remote control is lost or not working?
First, replace the remote battery with a CR2032 coin cell. If it still does not work, contact a Positron dealer to purchase a new remote and program it following the manual instructions.
Does the Duoblock FX 350 G8 require professional installation?
It is recommended, especially for proper connection to central locking and immobilizer. However, if you have good automotive electrical knowledge, you can install it yourself using the manual.
How do I program a new remote control?
Turn the ignition on and off, then press the valet switch a prescribed number of times. Details are in the installation manual. If not available, use the learning procedure described in the full manual.
What is the battery backup for?
The backup battery ensures the siren continues to sound and the system stays armed if the main vehicle battery is disconnected.
Can I enable silent arming?
Yes, press both remote buttons simultaneously or use the specific button. The alarm arms without chirping, only LED confirmation.
Will the alarm interfere with my car's central locking?
The Duoblock FX 350 G8 has a central locking integration output. It can be connected to your car's central locking system, provided the wiring is correctly matched.
Why does the siren randomly go off?
It may be due to a too sensitive shock sensor or a fault in the sensor. Reduce sensitivity, or check for loose connections. Also ensure the hood and trunk sensors are aligned properly.
