Common questions about manuals, registration, and support for this brand.
Firmware updates are typically performed using the Lightning Firmware Load Application. You must download the specific firmware file (.bk extension) from the BK Technologies service portal and connect your radio via the programming adapter (e.g., BKR0710).
This issue may require a battery characteristic file update. It is often resolved by inserting the battery into a BKR0303-2 Dual Unit Charger running firmware revision 3.0.16 or higher, which forces a calibration update.
Approved antennas, microphones, and batteries are listed in the user manual specifically for your model (e.g., BKR 9000). You can purchase official accessories through the BK Technologies online store or authorized dealers.
You can reach BK Technologies Technical Service Support by calling 1-800-422-6281 or by visiting their online service portal.
