  • Fixed a bug that caused the receiver to report transmitter battery voltage/status incorrectly.
  • Added customizable "Group" tuning feature, permitting quick and convenient access to four groups of up to 32 channels each.
  • Added "AutoOn" feature, so units with the necessary hardware support (sn# 1189 and above) can power themselves back on if the power was removed while on. Older units can be updated at a moderate cost to include this feature by contacting our service department.
  • Unit will now shut off automatically if the local battery voltage becomes critically low.

LR Firmware Update v1.18 - 17 August 2015

  • Added block 606 legacy feature, which can be used to pair band B1 and C1 transmitters with legacy block 606 receivers.

Block 606 is a special frequency range used in the United Kingdom.
