A TUVRheinIandffi’ www.tuv.com Report No.14017151 001 Appendix 7 User Manual Size: 140mm(W) x 177mm(H) Ver. 4 20 Jul, 2007 P2 INSTRUCTION MANUAL Model number : 261 N'UINC/BC/BUIN'E/N'I/BE Locations of Control Main Unit (Receiver) MAX/MIN BUTTON IE CLEAR BUTTON RESET BUTTON E] °CI°F BUTTON RE-SYNC BUTTON Remote Unit (Transmitter) RESET BUTTON - The configuration of your product may dilter somewhat lrom that shown in the illustration. the engraved battery marks inside the battery compartment tor the correct battery type. - “AA“ or "AAA" size battery. This product may use more than one piece of battery. Please refer to Feature - Indoor temperature and remote temperature - Centigrade or Fahrenheit readout Indoor, Outdoor temperature measurement range from -58°F ~ 158°F ( -50°C ~ 70°C ) - Temperature resolution 02°F ( 0.1°C ) - Main unit operation temperature from 32°F ~ 122°F ( 0°C ~ 50°C ) Before You Begin To ensure proper functioning of the Wireless thermometer, please follow this set up procedure. - Insert batteries for the main unit ( Refer to section of Battery Installation ) - Place the main unit as close as possible next to the remote unit and insert batteries for the remote unit. - Position the remote unit and main unit within effective transmission range, which in usual circumstances is 65 to 100 feet (20 to 30 meters). Note that the effective range is affected by the buiIding materials and where the main and remote unit are positioned, try various setup for the best results. Battery Installation Battery Installation of the main unit - Open the battery door - Remove whole set of old batteries Insert 2 fresh AA size batteries in place of the old batteries. Insert them in the proper position matching the polarity (+) and (-) as indicated. - Close the battery door - Press RESET button once Battery Installation of the remote unit - Open the battery door - Remove whole set of old batteries - Insert 2 AA batteries of new batteries in polarity ( + ) and ( - ) as indicated - Close the battery door - Press RESET button once Warning : Do not mix old and new batteries Do not mix alkaline. standard ( carbon—zinc) or rechargeable ( nickel cadmium ) batteries. Do not touch any other button or setting on your main unit. It will automatically receive the remote temperature signal after batteries inserted, P2 P. 3 R4 Getting Started Upon power up of the remote unit ( or pressing the RESET button ), the temperature RF signal is immediately sent to the main unit. The main unit attempts to search the RF temperature signal for 5 minutes after power up ( or pressing the RESET button ). If the RF signal is received within the first 5 minutes after power up of the main unit. the temperature will show on the outdoor temperature display, otherwise it will show blank --.-°F. After the remote unit temperature is shown on the outdoor temperature display, the synchronization of main unit and remote unit is established Place the remote unit outside in a shaded, dry area to protect it as if under an umbrella. If the RF temperature signal is not received within the first 5 minutes, press the RE—SYNC button on the main unit. The main unit will attempt outdoor temperature for another 6 minutes. Check INDOOR l OUTDOOR Temperature The indoor temperature is displayed on the INDOOR temperature field and the OUTDOOR temperature will be shown on the OUTDOOR temperature field. Maximum and Minimum Temperature The maximum and minimum recorded temperature reading will automatically be stored in the memory. Press the MAX/MIN button once to display the INDOOR maximum and minimum record. Press the button again to show the OUTDOOR maximum and minimum record. The respective indicator. INDOOR and OUTDOOR will be displayed. To clear the memory, press CLEAR button when the maximum and minimum temperature records are shown, it will clear the record of the shown temperature field. Display Unit The default unit for temperature is °F. press °CI°F button will toggle the display unit of temperature between °C and °F. Receiver Stage lndicator The RF signal indicator in the base unit remote temperature window will show the following: NO SIGNAL DETECTlON SIGNAL DETECTION ”H SUCCESSFUL RECEPTPDN Losing Synchronization of the Wireless Thermometer If the base unit displayed a proper remote temperature in the past but now displays blank --.-°F, the remote unit and the main unit may have lost synchronization If this occurs, press the RE-SYNC button of the main unit. The main unit will attempt outdoor temperature reception for another 6 minutes and reinitiate synchronization with the remote unit. If the remote temperature cannot be received, check: 1. The distance of the main unit or remote unit should be at least 34 feet away from any interfering sources such as computer monitors or TV sets. 2, Avoid placing the main unit onto or in the immediate proximity of metal window frames 3. Using other electrical products such as headphones or speakers operating on the same signal frequency ( 433MHz ) may prevent correct signal transmission and reception. 4. Neighbors using electrical devices operating on the 433MHz signal frequency can also cause interference. Note: When the 433MHz signal is received correctly, do not reopen the battery cover of either the remote unit or the main unit, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset both units. OthenNise transmission problems may occur. The maximum transmission range is 100 feet from the remote unit to the main unit ( in open space). However, this depends on the surrounding environment and interference levels. The temperature signal travels in a straight line from the remote unit to the clock. The signal will not curve around a blocking object. If no reception is possible, despite the observation of these factors, all units will have to be reset. Interference Signals from other household devices, such as entry controls, door bells and home security systems. may temporarily interfere with the units and cause reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of temperature reading will resume once the interference has stopped. Trouble Shooting I FAQ ( Frequent Ask Question ) There is no outdoor temperature shown on the unit? A : Press the RE-SYNC button on the main unit and the outdoor temperature will show within minutes. If no temperature is shown after 6 minutes of RE-SYNC button being pressed,the remote unit is either too far away or there is some interference between the remote and main unit. Bring the remote unit to the main unit and re—synchronize. Then move the remote unit to a new location closer and in direct line with the main unit. P4 P. 5 P5 The remote temperature is reading 405°C when the temperature is 155°C A : The remote unit is in direct sunlight. Move it to a shaded protected area. Care of Your Clock - Avoid exposing your clock to extreme temperatures, water or severe shock. ' Avoid contact with any corrosive materials such as perfume, alcohol or cleaning agents. ' Do not subject the clock to excessive force, shock, dust, temperature or humidity. Any of these conditions may shorten the life of the clock. - Do not tamper with any of the internal components of this clock. This will invalidate the warranty and may cause damage. Correct Usage of the Batteries - Use 4 AA batteries - Do not mix standard and rechargeable batteries - Do not mix new and old batteries - When the low battery mark CK} appears on the display. replace all batteries with new ones, when the low battery mark [3K]- appears on the REMOTE temperature field. replace all batteries of remote unit with new ones.
