:
Range measured is Line of Sight at 10ft elevation from Ground at different combinations of orientation of
transmitter and receiver, with special conditions were there is minimal or no RF interference from other sources. For best
case orientation of the ZigBits to achieve maximum range, refer to section 3.4.

Note: 1. For detailed characteristics, please refer [4]
2. To ensure compliance, the following regional specific settings are to be ensured:
FCC and IC compliance:
Operating the ZigBit from Channels 12 to 24 has no restrictions on Set power level.
Operating the ZigBit at Channel 11 requires limitation of TX output power to maximum +16dBm, the
power setting register value should be 0x0D or less
Operating the ZigBit at Channel 25 requires limitation of TX output power to maximum +13dBm, the
power setting register value should be 0x0E or less
ETSI Compliance: Operating the ZigBit in Europe requires setting TX Power to 0x0F for Channels 11 and 26.
All other channels can use a power setting of either 0x0E or 0x0F. This setting ensures compliance with ETSI
EN 300 228 clause 4.3.2.2 Maximum Power Spectral Density
