VR18: Real Time Clock Bug: February 28, 2006
VR18 Firmware versions up to and including v2.20 have a software bug that miscalculates leap year and RESETS the time & date to an earlier time/date. This bug will occur every 4 years beginning at 23:59:59 February 28, 2006 or if not powered at that time the first time it is powered on or after March 1, 2006.
VR18 Firmware Update v2.21 or later versions corrects this bug.
Observer I and II Software requirements after v2.21 or later firmware update
Observer I or II Software v2.20 will operate with VR18 firmware v2.21 but not later versions; update Observer Software to match or exceed the VR18 firmware version number.
Example:
VR18 v2.31 firmware requires Observer v2.31 but will work with later versions such as v2.32.
