Antenna Extensions
Coaxial cable can be connected to the standard SMA antenna connectors to extend the placement distance
of the antennas from the 3G NIM base unit. Using cables introduces signal loss in the antenna system, but
can be minimized by minimizing the length of cable used and using low-loss or ultralow-loss antenna
cables. Cables that do not match the antenna specifications are strictly prohibited for use with this device.
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.
6. Always disconnect the power to the unit before handling the NIM card, antennas, or cables.
Using improper cables may hinder the ability of the 3G NIM to communicate with a
cellular network. Refer to the documentation accompanying your cables to ensure you
have the right cables for this usage and that the cables meet the requirements specified
above.
