(1) Range is characterized in open office environments. Interfering RF sources in the
2.4 GHz spectrum, as well as absorptive objects occluding the RF communication path
may degrade transmission distance. Stated range can be exceeded under favorable RF
conditions.
(2) Battery duration is a function of charge and discharge conditions. Optimal battery per-
formance is obtained when the device is operated at room temperature. Note that the
stated Operation Time reflects the expected performance of a fully charged new battery
used in a sensor that is transmitting data. Operation Time is expected to decrease as a
function of charge cycles, and when the sensor is searching for a network.
(3) 80% of original battery capacity is maintained after 300 discharge/recharge cycles or
after 2 years if recharge cycles are less than 300. These values represent typical ex-
pectations under normal conditions. Actual performance will vary depending on usage
conditions.
(4) Operation beyond these temperature limits may damage the rechargeable battery.
(5) Input-referred noise is calculated as a root mean square over a 3 second window sam-
pled at 1926 kHz.
