If you own a , you already know it’s more than just a job site radio. It’s a rugged, water-resistant (IP64 rated), dual-power workhorse that keeps you connected via Bluetooth and provides clear audio while charging your 18V LXT batteries. However, like many modern smart radios, the DMR 112 runs on firmware. And occasionally, Makita releases updates to fix bugs, improve Bluetooth connectivity, or enhance user interface responsiveness.
: Currently, there are no widely available consumer software patches for the DMR112. Most "updates" for this model are handled internally by Makita Service Centers if the unit requires a hardware-level fix. Update Procedure (General)
(Invoking related search-term suggestions now.)
: Avoid using harsh chemicals like gasoline or thinner on the casing, as these can cause discoloration or cracks that might interfere with the IP64 protection. Technical Specifications Overview
If the DAB section is truly bricked (e.g., after a lightning strike near an antenna), the series DAB chip can be reflashed, but only with an external programmer (e.g., Segger J-Link) and the factory BIN file from the chip manufacturer (Silicon Labs), not from Makita.
That is normal. Contact Makita support directly using their online form or phone number. Explain your specific issue (e.g., "DMR 112 cannot lock onto DAB channels after a regional frequency change"). If a patch exists, they will provide it.
