Do not place the device alongside computer discs, credit or travel cards, or other magnetic media. The information contained on discs or cards may be affected by the device. Using accessories, such as antennas, that MultiTech has not authorized or that are not compliant with MultiTech's accessory specifications may invalidate the warranty.
SAFETY WARNINGS If incorrectly installed in a vehicle, operating the wireless device could interfere with the vehicle’s electronics. To avoid such problems, use qualified personnel to install the device. The installer should verify the vehicle electronics are protected from interference. Using an alert device to operate a vehicle’s lights or horn is not permitted on public roads.
SAFETY WARNINGS Keep the device on the opposite side of the body from the pacemaker to add extra distance between the pacemaker and the device. Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or jacket pocket directly over the pacemaker).
INSTALLING AND USING THE DEVICE Chapter 3 – Installing and Using the Device Installing the Device Connect suitable antenna(s) to the antenna connector(s). If your device is the serial version: Connect the DE9 male connector (9-pin) of the RS-232 cable to the RS-232 connector on the device, then connect the other end to the serial port on the other desired device.
If possible, use a USB port that connects directly to the motherboard rather than a USB port with added cabling inside the computer chassis. Use USB 3.0 ports if available. These ports are typically rated for more current. You can order the USB cable through MultiTech. The part number is CA-USB-A-MINI-B-3 Powering Down Your Device CAUTION: Failing to properly power down the device before removing power may corrupt your device's file system.
Some environments are harsher on particular bands. MultiTech products have antenna connectors at the best spacing for the product size. Placing antennas in close proximity to each other is not optimal, but you can do it if necessary. It depends on the signal strength to and from each antenna.
All antennas need to have a minimum flammability rating. Safety requirements depend on your final product. Unless otherwise noted, antennas certified by MultiTech are not approved for outdoor use. Do not extend these antennas outside of any building. Diversity and Power Draw There are no significant power draw differences.
