1. Introduction
This document provides a guideline for operating and configuring Castles S1F4CT
terminal.
The scope of this document includes setting up the terminal, basic operation, application
lifecycle, and some advanced features.
Regulatory instruction of usage
● Before using the terminal, please check has it been disassembled, modified, or showed
abnormal situation. If yes, please do not use.
● Please stay away from strong electromagnetic waves.
(Example) 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 connected water droplets evaporate.
● Static electricity may occur in some places (such as where you use a carpet).
● Please do not leave it in the sun for a long time.
● Please operate the unit carefully as it is a precision instrument. Do not apply impact,
drop or heavy objects on top of the unit.
● Do not attach dust, oil, etc. to a part of the power terminal. Also, please do not
scratch.

3. Appendix
3.1. FCC
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 minimum distance 20cm
between the radiator & your body.

3.2. IC
Industry Canada statement
This device complies with ISED’s licence-exempt RSSs. 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.
Le présent appareil est conforme aux CNR d’ ISED applicables aux appareils radio
exempts de licence. L’exploitation est autorisée aux deux conditions suivantes : (1) le
dispositif ne doit pas produire de brouillage préjudiciable, et (2) ce dispositif doit
accepter tout brouillage reçu, y compris un brouillage susceptible de provoquer un
fonctionnement indésirable.
Radiation Exposure Statement:
This equipment complies with ISED radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
