BK Radio® Service Bulletins

During power up, a potential “Source Fault Set” message temporarily flashes on the display. This is a firmware bug and does not affect the operation of the unit.

BKR0102 Li-Ion batteries are reporting incorrect capacities relative to the actual capacity of the battery.

Notification of warning when using non-authorized BKR battery chargers.

Notification of KNG Series Firmware release Ver. 5.7.7.

Additional Features and various Bug Fixes

Resolves the potential of the “Zone” not maintaining its set location after a power cycle.

Resolves the potential of the radio side connector accessory not being detected when installed on the BKR5000.

Resolves the potential PC application crash (“Blue Screen” Error) when connecting the radio to the PC.

Resolves the potential of having update flashing errors when updating firmware ver. 5.8.57.

Resolves the following potential issues: 1.) Unterminated cloning when cloning from a DPH, 2.) Will not power up due to “kernel” file loss or corruption, 3.) “Lock-up” during standby or in scan modes, 4.) DTMF “Live Dial” being inoperative

BK Technologies has identified a potential issue which could result in a radio not powering up when the radio operator places the switch into the on position. This condition has only been noted during the power up sequence and has not been noted after the radio has gone through a successful power up sequence.

Resolves potential Apache "log4j" vulnerability and the incompatibility issue with comma/ decimal internationalization settings in Windows. 

Resolves potential cloning issues.

No PTT transmit from accessory port, pin 12. This was caused from the previous firmware release 5.5.0q.

In some cases, if the PTT is pressed just after the boot-up “splash screen” occurs when the display is present, the transmitter will lock-up.

Due to a revision change to the KNG-M Touch Screen Display from the display manufacturer, the KNG-M firmware had to be modified to make the new display compatible with the KNG-M Series.

A radio lockup or faulty operation may occur if the firmware versions between the KNG-Mxxx/KNG-MxxxR series and the connected Control Heads (KAA0660 and KAA0670) does not match.

Radio powering up with a “DSP Failure” error.
