1. Introduction

This document provides a guideline for operating and configuring the Castles S1U2-M4 terminal. The scope includes setting up the terminal, basic operation, application lifecycle, and some advanced features.

Regulatory instruction of usage

• Before using the terminal, please check if it has been disassembled, modified, or shows any abnormal situation. If so, please do not use it.
• Please stay away from strong electromagnetic waves (e.g., microwave ovens, magnets, shoplifting prevention devices, high-voltage wires, automatic doors, communication antennas, etc.).
• Condensation can occur when moving from a cold place to a warm place. If condensation occurs, do not use the unit until the water droplets have evaporated.
• Static electricity may occur in some places (such as where you use a carpet).
• Please do not leave the terminal in the sun for a long time.
• Please operate the unit carefully as it is a precision instrument. Do not apply impact, drop, or place heavy objects on top of the unit.
• Do not attach dust, oil, etc., to any part of the power terminal. Also, please do not scratch it.
• Operating Temperature: -20 to 70°C.

Federal Communication Commission Interference Statement

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

FCC Caution:

• Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment.
• This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body.

Note: The country code selection is for non-US models only and is not available to all US models. Per FCC regulation, all WiFi products marketed in the US must be fixed to US operation channels only.
