Version History: Version 1.6.1 Field Update: contains Firmware Revision 1.6.1 and Interface Revision 1.6.1. Version 1.6.2 Field Update: contains firmware revision 1.6.1 and interface revision 1.6.2. Interface revision 1.6.2 fixes a minor bug where the bias dither frequency and voltage were not updated correctly on the home pages for MBX, G, and A models. This bug only affected the display (the hardware was set to the requested voltage and frequency, whether the settings were changed via the LCD GUI or by remote control, but the displayed values on the home pages were not updated to reflect the changes). Firmware update 1.6.2 fixes a minor bug where after turning on the amplifier, putting the unit to sleep with the standby button, waking up the unit again, then turning on the amplifier again, the green dot on the display used to indicate that the amplifier was in a stable "on" state would never stop flashing, even though the amp was actually behaving normally. This bug only affected models with amplifiers, and only the display was incorrect -- the amp would actually power on as requested.
