During the test, some sources of electrical interference should be avoided, such as signal towers, base stations, utility poles, making calls, sending and receiving text messages, etc.

Feature:
Premium Material: The housing is made of solid plastics material, fallproof, wear resistant, and with nice durability. Digital Display: 4-bit digital display of radiofrequency micro-computer measuring instruments, you can see the tested frequence clearly. LED Light Design: The instrument is equipped with LED illumination, which is more convenient for using in the dim light environment. Indicator Light: Equipped with an infrared input indicator, the red light shows that the infrared output of the remotes control is normally emitted; If the indicator is off, means the infrared emitter failure, damage or other reasons. 9V Battery Power Supplys: Built-in a 9V battery, large capacity and can provide long service time.
Seems a good remote tester, able to display the operating frequency. I have tested Ok my car key and the garage doors remote, both operating at 433 and 434 MHz. It says in its case that it works from 100-1000 Mhz, but I have not tested it at higher frequencies yet. Also I have not tested its IR capabilities yet but seems limited to IR detection, yes-no; no further info. It came with 9V battery included
