Additional Warnings
The following are guidelines and warnings for wireless access devices.
1. Do not operate RF devices in an environment that may be susceptible to radio interference
resulting in danger, specifically:
Areas where prohibited by law.
Areas where explosive atmospheres may be present.
Areas where medical or life support equipment may be present.
On an aircraft, either on the ground or airborne.
While operating a vehicle.
2. Do not touch or move antennas while the unit is transmitting. Do not hold any unit containing a
radio so that the antenna is close to, or touching, exposed parts of the body while the unit is
transmitting.
3. The antennas and units are designed to operate in an indoor environment only.
4. Avoid connecting or disconnecting cables during periods of lightning activity.
5. When handling the 3G NIM and antennas, wear grounding straps to avoid ESD damage to the
card. Touching the rear panel with your hand or any metal tool can result in a shock.
