5.3.5.2 Cellular signal strength
The terminal then displays the current operator and signal strength for the base
station with which it is communicating.
Note: A signal strength of 010 CSQ or higher is recommended for a reliable
connection.
If the signal strength is below or close to minimum then try to reposition the antenna or use an external high
gain antenna to improve signal strength (if necessary). Re-run the signal strength test and reposition again if
necessary to gain best signal strength possible.
When the signal strength is as good as you can get it, click «Continue».
5.3.5.2.1 For the 50 (DS2220/IRIS-4 50)
On this terminal you can press and hold the "SW" button for 3s which will let you see the current signal
strength indicated across the LEDs:
5.3.5.2.2 For the 6xx with cellular connection
Use the LEDs on the 6xx to perform a signal strength check.On the 6xx you can press and hold the "AP"
button which will let you see the current signal strength indicated across the LEDs. The SYS LED remains
flashing and the signal strength is indicated from the POL LED.
For a reliable cellular connection, a signal strength that lights three or more of the indicating LEDs is
recommended:
