The Panasonic WX-CS560 Speaker/Microphone is used as both the speaker and the microphone elements in the speaker post
The WX-CS560 is not a weatherproof unit and must be housed in an enclosure
A speaker post must be used to ensure best operation
A menu board may be used if it is designed to properly hold a speaker and a microphone and the distance to the car is not excessive
Best distance from the speaker post to the car is 3 feet or less
Distances over 3 feet will increase ambient noise and echo greatly degrading performance
The speaker and microphone must be installed in the acoustic foam supplied with each unit
ALL QUALITY starts with the proper installation of the speaker post. Any error here will be amplified down the line
