TECSUN PL-380 with New Function - ETM (Easy Tuning Mode) This function is similar to ATS (Auto-tuning Storage)! ETM can scan through the whole frequency band and select all the available stations. However, unlike ATS, ETM will not store or replace those exiting memories with the new scan. It works just like a fast tuner; it is easily tune to the next available station by a click of the tuning wheel. You may find this function is useful when you are travelling to other country! Because you can use ETM to scan through the frequency band without delete or replace any of the memory that is stored back home.
