2.Easy optical alignment with LED indication
* 7-level LED indicator which can be checked the beam
   strength easily.
* Highly accurate alignment with no need to use a
   voltmeter.
* No need for beam blocking plate.

LED level meter for beam alignment. Two LEDS on the receiver act as a level meter to visually disply the beam reception level Each LED changes flickers more quickly--flickers  quickly--flickers slowly---turns off. 7-level LED indicator enables quick and accurate beam alignment.
