Removing a SIM Card

To remove the SIM card, push the SIM card in. The device ejects the SIM card.

Mounting Device to Flat Surface

1. Locate the groove on the bottom of the device.
2. Slide the mounting bracket through the groove.
3. To secure the bracket to the desired surface, place and tighten two screws in the holes on either end of
the mounting bracket. The dimensions illustration in this guide shows the mounting bracket, as well as
the dimensions for placement of the screws.

LTE Antenna MISO

LTE devices use Multiple Input and Single output (MISO) to improve the downlink connection (cell tower to
mobile). It has no effect on the uplink (mobile to cell tower).
Important: Always connect all included antennas for increased downlink bandwidth and better signal handling
in diverse locations. You must deploy with two antennas, unless your carrier has authorized you to deploy with
one antenna.

Selecting Antennas

Select an antenna based on your product and application. Typically, both antennas are the same and either can be
the main receive antenna.

Placing External Antennas

Antennas are usually a quarter wavelength apart from each other. With multiband radios where the quarter
wavelengths in each band are diverse from each other, this rule may not be practical. Choose spacing based on the
band used most often or the band with connection difficulty. 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.
If the antennas are too close together for your application, use a similar antenna on a short cable for the second
receive only antenna.

Antenna Approvals and Safety Considerations

Note the following:
Carriers conduct antenna diversity tests.
There are no EMC concerns about antenna diversity.
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.
