K200S Amplified Repeater
1 Part Description: K200S Wireless Amplified Repeater
2 General Description and Purpose
The K200S device is designed to be portable or directly mountable within the desired
location: Applications include fridges, freezers, cold rooms and ambient storage.
The K200S is equipped with an RF amplifier which increases the range of the device.
The K200S implements battery booster technology which allows the sensor to function at
lower temperatures and extends the battery life.
Each K200S has an internal digital sensor which is calibrated and verified by Kelsius.
The K200S is activated by operation of the recessed on/off switch at the bottom of the
device. (left position On, right Position Off)
The K200S communicates with the Network Controller wirelessly and directly, or via
Repeaters, even when buried deep inside storage cabinets.
This equipment design typically applies to commercial or industrial equipment expected
to be installed in locations by Kelsius trained engineers and where only adults are normally
present.

3 LED Indications
Green LED
The Green Led (Fig.2) will indicate the power up sequence and if an established
communication link has been discovered.
On power up the device will illuminate two times. After power up it will indicate if the
device is communicating with a network controller.
• If the K200S is installed and communicated to a Kelsius Network Controller, the
green LED will flash six times.
• If the K200S is not installed on a network controller the green LED will flash once.

FCC Interference Statement
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 or more 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.
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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.

Economic Development Canada's licence-exempt RSS(s). Operation is subject to the following two
conditions: (1) This device may not cause interference. (2) This device must accept any interference,
including interference that may cause undesired operation of the device.
ISED Canada — Avis d'exemption de licence (CNR-Gen, Français)
L'émetteur/récepteur exempt de licence contenu dans le présent appareil est conforme aux CNR
d'Innovation, Sciences et Développement économique Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) L'appareil ne doit pas
produire de brouillage ; (2) L'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le fonctionnement.
RF Exposure Statement (FCC / ISED RSS-102)
This equipment complies with FCC and ISED radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20 cm
between the radiator and any person.
Cet équipement est conforme aux limites d'exposition aux rayonnements de la FCC et d'ISDE établies
pour un environnement non contrôlé. Cet équipement doit être installé et utilisé en maintenant une
distance minimale de 20 cm entre la source de rayonnement et toute personne.
