Error symptom 3: 
The power setting usually has a value close to or identical to the set Power Ramp high limit. 
Countermeasure 3: 
Increase the Power Ramp high limit. If this is not possible, modify the antenna configuration 
(see example Example of an application "optimize a
ntenna position" (Page 67)) or select a 
different antenna. 
 
Error symptom 4: 
The Power Ramp low limit is never adequate to identify the transponders. Too many steps 
are required to reach the necessary power. 
Countermeasure 4: 
Increase the Power Ramp low limit and, if necessary the step size (Boost Step Size ANT1 or 
Boost Step Size ANT2).
