HN-1010/1510 

Set Range Optimization 

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.
