N9ZTHX301MPart 15 Security / Remote Control Transmitter

Thermo sensor Model: THX301 Instruction Manual Congratulations on your of purchasing our new long range outdoor thermo-hygrometer senor which can cover up to 75m range in an open area. This sensor is designed for everyday use for the home or office and used to monitor the temperature and humidity change of outdoor sites. A D C B Features A. LED indicator Flashes when remote unit transmits a reading. B. Channel number Indicates the remote sensor is set to which channel and the user can find the corresponding reading in the same channel in the linked receiving unit. C. Temperature/humidity display Display the measured temperature and humidity Description of buttons The remote sensor has 3 function buttons inside the battery compartment 1. [CH] button After the battery installation, the LED blinks slowly every 1.5 seconds and channel number shows ‘1’ to indicate it is now under channel setting mode and is set to channel 1 by default. If the user presses no key within ten seconds, the unit will auto-exit the channel setting. If the user press [CH] button once during the channel setting, the channel number is changed to ‘2’ to indicate the unit is set to channel 2. If the user press [CH] button again, the channel number will be advanced to channel ‘3’ and so on. The maximum channel number is ‘5’ and the unit will be scrolled back to channel ‘1’ at the 5 th press of the [CH] button. 2. [C/F] button Press to toggle unit °C or °F 3. [ RESET ] Button Press to hardware reset the unit to factory setting Setting procedure to link up with a receiving unit This device is designed for easy set up with no wire installation. The following steps are required to be done in proper sequence to link up with a receiving unit. Please insert batteries for the receiving unit before doing so for the remote unit. 1. Remove the bracket stand. 2. Unlock two latches in the bottom to release the semi-transparent jacket. 3. Slide down the battery door in the back. 4. Insert 2 pieces AAA size batteries according to polarity marking on the battery compartment. 5. The LED blinks slowly to indicate it is under the channel setting mode and the user can set it to other channel by press [CH] key. 6. The temperature of the sensor will appear on the selected channel of the receiving unit if it is linked up with the receiving unit successfully. 7. Close the battery door and use two latches in the bottom to lock it with the semi-transparent jacket. Follow the same procedure (1 to 7) to register other remote sensors. Note: For the user purchasing more than one remote sensor, he must set the sensors to different channel in the start up to avoid conflicts. Precautions a. Do not clean the unit with abrasive or corrosive compound. It may scratch the plastic parts and corrode the electronic circuits. b. Do not subject the unit to excessive force shock, dust, temperature or humidity, which may result in malfunctioning, shorter electronic life span, damaged battery and distorted parts. c. Do not tamper with these units’ internal components. Doing so will invalidate the warranty on the unit and may cause unnecessary damage battery and distorted parts. d. Do not subject the unit to excessive exposure to direct sunlight. The remote sensor is splash proof. Never immerse it in water or expose to heavy rain. e. Always read the users manual thoroughly before operating the unit.
