Unit Installation
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.
6. Always disconnect the power to the unit before handling the NIM card, antennas, or cables.
