Set Range Optimization (remote only)
This command applies an adjustment factor to the over-the-air timing of remotes to
compensate for the effects of propagation delay at long ranges. The default setting of
00H is suitable for ranges of 0 to 0.8 miles (1287 m), with optimal performance at 0.1
miles (162m). Each increment of this parameter adds 0.1 miles (162 m) to the working
range. Thus the optimal and max ranges are determined by:
optimal = 0.1mi + 0.1mi x dx = 0.17km + 0.17km x dx
max = 0.8mi + 0.1mi x dx = 1.33km = 0.17km x dx
The following table presents various values of dx and the associated optimal and max ranges.
