Before final placement or mounting, ensure that the wireless signal strength is strong enough for the chosen 
area. Once the unit has established connection to the wireless network, the Link Status LED will blink (75 ms on 
and 3 seconds off), then you can look to the signal indicators. To find your signal strength, look at the LED 
indicators on the front panel. If the first indicator is lit (“one bar”), there is sufficient signal strength for proper 
operation. If two or three are lit (two or three “bars”), then there is good signal strength and operation will not 
be impaired.
