Specifications:Operating Instructions Main Station: Temperature Range –40F to 392F (40°C to 200°C) LLL indicates reading less than –40F (40°C) HHH indicates reading more than 392F (200°C) Display resolution 1 degree C/F Indoor temperature Temperature range 32F to 122F (0°C - 122°C) LLL indicates reading less than 32F (0°C) HHH indicates reading higher than 122F (50°C) 1. Normal operation – The Main Station automatically links up to three remote transmitters. If more than one sensor is being used the next higher channel is automatically selected. If all three channels are in use, the main station will automatically replace Channel 1. 2. C/F button – on back of unit is used to toggle between Centigrade and Fahrenheit. 3. Hi/Low Button – Pressing the Hi/Low button on back will toggle between higher than and lower than temperature set points. This is indicated by arrows on the LCD screen. 4. Channel Button – on back will change channel display when multiple sensors are used. A Channel Auto scroll feature in enabled by holding the Channel button down for 2 seconds. The remote temperature display will then display each remote sensor for 2 seconds. 5. Hi/Low Button & Channel Button – When pressed together it allows toggling between indoor temperature display or set temperature display. 6. Set Button – on front is used to set remote temperature alarms. Depressing the set button will allow a toggle between channels when multiple sensors are in use. 7. Up arrow – pressing the up arrow on front is used in set mode and will increases the set temperature 1 degree per second. 8. Alarm Set Point Reached – When more than one remote alarm set point is reached the left most display will be overwritten with the temperature with the remote sensor temperature that has reached its set point. 9. Alarm – The Alarm will sound when the set temperature is reached until. Battery Life – 5 months depending on use Low Battery indicators – if remote sensor batteries or main station batteries are low an icon will be present on main station. Caution: Do not mix alkaline batteries with Cadmium or Lithium batteries. Note: The temperature displayed is taken from the interior sensor unless probe is used. When the probe is used the temperature display is form the probe itself. 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. A. Any front key is pressed (Set or Up arrow) B. The Alarm Times Out after 1 minute NOTE: 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.

Administratively, there is one small thing for each application. 1. 15.19 statement - The wording is slightly incorrect. The FCC is a stickler for these things. So, please revise and send back. I have attached a sample to assist you. Have a good day. 15.19 statements.pdf Marianne T.

FCC ID: N9Z-NU-701 Circuit Description The 433.92MHz crystal oscillator drives the base of Q9 the final/buffer amplifier. The modulation provided by Mic. The output of Q9 has the matching network consisting of L1, L3, C21 and C19 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 9 Volt (“6F22” size battery x 1) primary battery

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigate all operating modes, rotated about all 3 axis (X, Y & Z) to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. *:OATS [Open Area Test Site] located at HKSTC with a metal ground plane on filed with the FCC pursuant to section 2.948 of the FCC rules, with Registration Number: 90657.
