Precautions Regarding the Sensors Provided with the Remote Unit
Temperature Sensor TR-5106 (Provided with RTR502B)
Submersible
①
②
Materials: ① Thermistor ② FEP Coated Electrical Wire
• Do not bend or press the last 5cm to the tip of the sensor, as this may damage it.
• If the FEP coating on the sensor and/or the cable has a defect or tear, the waterproof
capacity will be lost. Inspect it before operation.
• Insert the sensor tip to at least 5cm or more to obtain an accurate temperature measure-
ment.
• Use the sensor within its resistance range (-70 to 180° C).
Temperature-Humidity Sensor TR-3310 (Provided with RTR503B)
① ② ③
Materials: ① Temp-Humidity Sensor ② Polypropylene Resin ③ Vinyl Chloride Coated Electrical Wire
• This sensor is not water resistant. Do not expose to condensation, dampness, corrosive
gases or organic solvents. If the sensor gets wet, immediately remove the sensor from the
unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in
normal room temperature before using it again.
• Do not expose the sensor to a strong impact. This may adversely aect measurement
accuracy and cause damage or malfunction.
• Continued use may cause a decrease in the sensor's accuracy and sensitivity even under
normal operational conditions. Periodic calibration may be required.
• When the sensor is not to be used for a long period of time, please store it at normal
temperature and humidity.
High Precision Temp-Humidity Sensor SHB-3101 (Provided with RTR507B)
Temperature Humidity Sensor
① ② ③
Materials: ① Temp-Humidity Sensor ② ABS Resin ③ Vinyl Chloride Coated Electrical Wire
• This sensor is not water resistant. Do not expose to condensation, dampness, corrosive
gases or organic solvents. If the sensor gets wet, immediately remove the sensor from the
unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in
normal room temperature before using it again.
• When continually used in environments with temperatures above 60
C, accuracy of
humidity measurements will decrease over time. Also, humidity cannot be measured at
temperatures below -20
C.
• Do not expose the sensor to a strong impact. This may adversely aect measurement
accuracy and cause damage or malfunction.
• Continued use may cause a decrease in the sensor’ s accuracy and sensitivity by about
1% per year even under normal operational conditions.
• When the sensor is not to be used for a long period of time, please store it at normal
temperature and humidity.
Compliance Information
<For FCC Model>
FCC 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 o
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 dierent from that to which the receiver is
connected.
-
Consult the dealer or an experienced radio/TV technician for help.
Caution: Changes or modications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
This transmitter must not be co-located or operated in conjunction with any other antenna or
transmitter.
ISED Statement
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science
and 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 interfer-
ence, including interference that may cause undesired operation of the device.
This digital apparatus complies with CAN ICES-3(B)/NMB-3(B).
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.
Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.
FCC/ISED Radiation Exposure Statement
This equipment complies with FCC/ISED radiation exposure limits set forth for an uncontrolled
environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the ISED
radio frequency (RF) Exposure rules. This equipment should be installed and operated keeping the
radiator at least 20cm or more away from person’ s body.
Cet équipement est conforme aux limites d’exposition aux rayonnements énoncées pour un environne-
ment non contrôlé et respecte les règles les radioélectriques (RF) de la FCC lignes directrices d'exposition
et d’exposition aux fréquences radioélectriques (RF) CNR-102 de l’ISDE. Cet équipement doit être installé
et utilisé en gardant une distance de 20 cm ou plus entre le radiateur et le corps humain.

Important Notes about Use of Wireless Products
Operations in the 5GHz WiFi band are restricted to indoor usage only.
Wireless products cannot be used in countries other than where those products have been
approved for use, according to that country's wireless regulations.
T&D Corporation shall in no manner whatsoever take responsibility for the usage of these products,
nor be liable in any manner for legal consequences stemming from the usage of these wireless
products in unapproved areas.
• When inserting a battery, make sure no water or foreign objects get inside the case.
• To maintain waterproof capacity, when changing batteries also change the rubber
packing and the drying agent (silica gel).
Lithium Battery
• When using an LS14250 type lithium battery, even though a new battery has been
inserted the [ ] indicator may remain on for a short time. This is due to a special
characteristic of the battery. Note that the longer the battery has been in storage the
longer the amount of time, from 10 minutes to about 1 hour, the battery warning mark
will remain on. If during that time the Base Unit is used to get the current status of the
Remote Unit, the remaining battery level will show that the battery level is low.
• Please store the LS14250 in a place that is 20° C or less.
• The estimated battery life of the Lithium Battery LS14250 is about ten months if recorded
data is downloaded once a day or the monitoring occurs once every 10 minutes.
• When using lithium batteries other than LS14250 produced by SAFT, such as CR2, product
specications cannot be guaranteed nor can the performance of some functions, such as
the battery warning function.
• Please avoid using the CR2 in the following situations:
Using the unit in an environment below 0 ° C or above 60 ° C
Exposing the CR2 to continuous vibration such as in transportation
• When using a CR2 lithium battery, the tube is not necessary
• To maintain waterproof capacity, when changing batteries also change the rubber packing
and the drying agent (silica gel). When using a CR2 lithium battery, please purchase the
optional Maintenance Set (TR-00P1) to replace the rubber packing and silica gel.
Operating Environment
• Use in high or low temperature environments will result in a shortening of the battery life.
In environments of 60℃ or higher, not only will battery life be shortened but the unit itself
and its parts will deteriorate more rapidly. Please do not use in such environments for
prolonged periods of time.
-20℃ ----- one half of life compared to normal temperatures
-30℃ ----- one third of life compared to normal temperatures
60℃ ------ one half of life compared to normal temperatures
• Although under normal temperature environments the ［bAtt] or [ ] mark may not
appear, it may still become impossible to carry out communication in low temperatures.
