BLX Transmitter and 1.5V Lithium Cell

Date Updated: September 13, 2017
I have a BLX2 transmitter. When I use an Energizer non-rechargeable lithium 1.5V battery / cell, the red LED flashes. Guidance, please.

This issue occurred with the early BLX transmitters.  It has been resolved with a firmware revision.
Shure Service will do a firmware update that will fix this issue. Please contact Shure Service at 800-516-2525 for instructions on returning the BLX transmitter for the firmware change.
