Section 4:
Operational Precautions
4.1 General Safety Instructions
When using the SR14+ABC reader, general safety precautions should always be
followed.
1. Handle bare boards with care
2. Only operate the product with the indicated power supply requirement

4.2 Installation
SR14+ABC reader is a contact-less smart card reader, which uses inductive coupling
to communicate with contact-less cards. Precaution must be taken to keep the reader
far enough from metal surfaces. Refers to table below for general guidelines.
Installation of reader near a metal surface may dramatically shorten the operating
distance and increase power consumption
Descriptions Clearance
Antenna positioned above metallic
Recommended to be > 20mm away
surface (ferrous or non-ferrous metal
alike)
Any edge or sides of the antenna
Recommended to be > 20mm away
against any metal surface (ferrous or
non-ferrous metal alike)
Any closed loop formed by metal in
close proximity to antenna
To be avoided at all times! Especially
within 100mm facing directly parallel to
the antenna top face.
Figure 4.1 Installation Recommendations
Please notice that installation recommendations served as a general guidelines for
SR14+ABC reader installation. It does not guarantee the performance to be consistent
over every reader installed under different scenarios.
Fine-tuning or adjustment of the antenna may still be required to achieve optimal
performance.
4.3 Diagnostic Status Indicators
Conditions Descriptions
LED – All 4 LED ON Performing Power-On Self Test during
Boot-up
Any of 4 LED remains ON after PowerON Self Test
If any of the 4 LEDs remain ON after
Built-in Self Test on Power-Up, there is
error occurred and should be send for
technical troubleshooting.

Section 5: Compliance Statement
This product is currently pending certification for the following compliances:
1. CE
2. FCC
3. EMC: EN61000-6-4: Part 6-4 – Generic Standards – Emission standard
for industrial environment
4. EMC: EN61000-6-2: Part 6-2 – Generic Standards – Immunity standard
for industrial Environment
Regulatory Notes
An RFID system comprises an RF transmission device, and is therefore subject to
national and international regulations. Prior to the powering and operation of the
SR14+ABC reader, relevant compliance certificate should be obtained from the
associated watchdog agency. Sale, lease or operation in some countries may be
subject to prior approval by the respective government body or other international
compliance organization.
For operation of radio telecommunication equipment in the European Union or in
countries where the CE (Conformité Européene) mark is recognized, Kenetics
Innovations, hereby, declares that the SR14+ABC Reader is in compliance with the
essential requirements and other relevant provisions of the European Council’s
R&TTE directive 1999/5/EC. Note that the SR14+ABC Reader is supplied with its
own integral antenna. Users and installers are welcomed to consult the R&TTE
directive 1999/5/EC as well as the ETSI EN 302-291-1/2 harmonized standard
whether further compliance testing is required if they intend to use their own antenna
with SR14+ABC reader control board.
In addition, the length of external cables connected to interface 10 pins of
SR14+ABC reader should not exceed 3m. Cable lengths exceeding 3m may not
necessarily degrade the performance of the reader but would have to be subject to
further compliance test associated with the CE mark. Kenetics will not be liable for
cable installations that exceed 3m.
For countries requiring FCC certification, a typical system configuration
containing the SR14+ABC reader has been tested and found to be compliant with the
limits for a FCC Part 15C (intentional radiator) device. Nonetheless, it is still the
responsibility of the customers to have their complete system tested and approved for
use from the appropriate compliance agencies/authorities before operating or selling
the system. As part of FCC part 15 compliance requirements, it should be noted that:
• Modifications not expressly approved by this company could void the user’s
authority to operate the SR14+ABC reader.
• The SR14+ABC reader complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) The SR14+ABC reader may not
cause harmful interference, and (2) must accept any interference received,
including interference that may cause undesired operation.
