Battery Backup Operation
The Tropos 5210 Wi-Fi cell may contain an automatically recharging battery, which provides an
integrated uninterruptible power supply (UPS). The available backup time depends upon the
level of network traffic serviced by the cell and the ambient temperature. Figure 24 shows the
relationship between average throughput and battery uptime.
Note
The internal battery is not field replaceable.

Safety Information for the Tropos 5210 Wi-Fi Cells
The Federal Communications Commission (FCC) with its action in ET Docket 96-8 has adopted
a safety standard for human exposure to RF electromagnetic energy emitted by FCC certified
equipment. The Tropos 5210 products meet the uncontrolled environmental limits found in
OET-65 and ANSI C95.1, 1991. Proper operation of this radio according to the instructions
found in this manual and the hardware and software guides on the Tropos 5210 Wi-Fi cells result
in user exposure that is substantially below the FCC recommended limits.
The following are guidelines to insure safe operation of the Tropos 5210 Wi-Fi cells:
 Do not touch or move the antenna(s) while the unit is transmitting or receiving.
 Do not hold any component containing a radio such that the antenna is very close to or
touching any exposed parts of the body, especially the face or eyes, while transmitting.
