The Ethernet RJ45 port incorporates two indication LEDs. The Link LED comes on when there is a connection on
the Ethernet port, and will blink off briefly when activity is detected on the Ethernet port. The 100-MB LED indicates
that the connection is at 100 MBit/sec. The 100-MB LED will be off for 10 MB/sec connection. Other conditions
indicating a fault are described in “Chapter 4 - DIAGNOSTICS.”

• 9 x non overlapping 1.25-MHz channels
• 9 x partially overlapping 2.5-MHz channels
• 4 x non overlapping 5-MHz channels
• 4 x overlapping 10-MHz channels
• 2 x overlapping 20-MHz channels
If operating in Australia, the frequency range is 915–928 MHz and the available channels are as follows:
• 4 x non overlapping 1.25-MHz channels
• 4 x partially overlapping 2.5-MHz channels
• 3 x overlapping 5-MHz channels
• 1 x 10-MHz channel
If operating in Hong Kong, the frequency range is 922–925 MHz and the available channels are as follows:
• 2 x non overlapping 1.25-MHz channels
