Frequently Asked Questions - X4 Roxim

How do I mount the Roxim X4 to my handlebar?

Use the included handlebar mount (BPC-126U). Secure the bracket to the handlebar, then slide the light onto the mount until it clicks. Tighten the screw if needed.

What are the different power options for the X4 series?

The X4, X4A, and X4W use an integrated USB lithium battery. The X4AN uses a 4AA battery box (included). You can also use an external USB power bank with the X4W model.

How do I charge the integrated battery?

Connect the light to a USB wall charger or USB port using the provided cable. Ensure the charger outputs constant current >1A. The green LED turns steady while charging and off when complete. Blinking green indicates an incompatible charger.

What is the difference between Manual and AUTO mode?

Press the button for 0.5 seconds for Manual mode, where you cycle through brightness levels (HI, MID, LOW). Press for 2 seconds for AUTO mode, which activates smart features: DRL during daytime, stop detection (light dims after 30s stop, turns off after 4 min), and ambient light sensor (main LED on when dark).

How do I interpret the battery status LED?

The 4-lamp indicator shows: steady blue = full; blinking blue/red = below 70%; slow red = low; fast red = below 5%. Note: In AUTO mode, the indicator only shows status when battery is low.

Can I use alkaline batteries in the X4AN?

No, alkaline batteries are not recommended. Use rechargeable AA batteries for better performance and compatibility.

What should I do if the light does not turn on?

Check the battery connection. For X4/X4A/X4W, charge the battery with a compatible charger (≥1A). For X4AN, ensure batteries are installed correctly and have charge. If the green LED blinks during charging, the charger is incompatible.

Is the Roxim X4 helmet mountable?

Yes, with the optional Helmet Mounting Kit (MB XF). You can attach the mount to your helmet with the provided straps, then clip the light onto the mount.

How do I switch from AUTO mode back to Manual mode?

In AUTO mode, press the button once to exit AUTO and enter Standard (Manual) mode. You can then toggle brightness with short presses.

Where can I find the user manual for the Roxim X4?

The manual is available for free download in PDF format from notice-facile.com or the Roxim website ([e-mail]). It covers mounting, connection, charging, and operation instructions.
