4.1. Microphone
The microphone is placed behind perforated part of front panel. Its sensitivity
can be adjusted from superior system via Ethernet interface.
4.2. ALS indication LED
Behind perforation of front panel are concealed the LED indicators, which
allows the user an identification of device which communicates at given
moment. Diodes blinks red, when the RRAS-MC/A1 unit recognizes its IP
address within the Ethernet frame.

6. Configuration
All microphone parameters are configured through Ethernet interface.
6.1. Factory setting
The microphone set is fitted with „RESTORE“ button to get into factory setting.
This button is accessible at the cover upper side. To push the button use a tool
(stick) with maximum diameter 1.5 mm. Do not use tools with sharp tip!
The button should be pressed while switching the power supply on ca. 5 sec.
Successful restoring of factory setting is indicated by short blink of green LED,
located on rear cover. Release the button after start of LED blinking.

7.1. Installation rules
Connect the terminal PE on the microphone rear cover with vehicle frame.
For service and within the distributor box is enough to use an unshielded cable
(the patch cable).
Apply the STP cabling for permanent use outside the distributor frame.
All wired connections to PE terminal must be realized with as low as possible
impedance. Technical parameters of unit are guaranteed only when these
wiring rules are applied.
