1. TEMP • Input temperature correction.
• Correct the TEMP. data according to the PWB ambient temperature, and input it.
• Since the temperature rise causes error of temperature sensing part (RF IC), the following requirements must be observed.
1
Perform the TEST mode without mechanical connection.
2
This operation must be performed quickly after power is supplied.
