  • Page 7: Installing Batteries

    INSTALLING BATTERIES Your thermometer system requires four AA batteries (not supplied) for power — two each for the main unit and the remote sensor. For the best performance and longest life, we recommend RadioShack alkaline batteries. Cautions: • Use only fresh batteries of the required size and recommended type.
  • Page 8: In The Remote Sensor

    Notes: • If you use the remote sensor in tem- peratures below –4°F (–20° C), we recommend you use lithium batteries in the remote sensor. • Install batteries in the remote sensor first, then in the main unit, to give the main unit time to find the remote sensor’s signal.
  • Page 9 1. Use a Phillips screwdriver to remove the screws in the battery compart- ment cover, then lift off the cover. 2. Set inside the CHANNEL °C/°F compartment to the desired set- tings. (See “Setting/Selecting the Display Channel” on Page 18 and “Changing the Degree Format”...

    Warning: Dispose batteries promptly and properly. Do not burn or bury them. Caution: If you do not plan to use the system for a month or longer, remove the batteries. Batteries can leak chemicals that can destroy electronic parts. In the Main Unit 1.

  • Page 12: Selecting A Location

    Selecting a Location Choose locations for the main unit and remote sensor that are within about 328 feet (100 m) of each other. The main unit should be located indoors, but the remote sensor can be placed either indoors or out.
  • Page 13: Mounting The Main Unit

    • Do not place the main unit in a location where it is likely to get wet. Only the remote sensor is weather- resistant. • Do not place the main unit or remote sensor near electrical appliances or heating or air conditioning vents.

  • Page 15: Mounting The Remote Sensor

    Mounting the Remote Sensor To set the remote sensor on a flat sur- face , insert the ends of the supplied wire stand into the holes on the back of the re- mote sensor. To mount the remote sensor on a wall (or on a post outdoors, for example), you need two -inch (3.5-mm) screws (not...

    Note: If the main unit does not receive or stops receiving a signal from the remote sensor, appears. If this happens, force a signal search (see “Forcing A Sig- nal Search” on Page 30) or reset the main unit (see “Resetting the System” on Page 31).
  • Page 21: Changing The Degree Format

    CHANGING THE DEGREE FORMAT You can view the temperature in degrees Fahrenheit (°F) or degrees Celsius (°C) on the main unit and on the remote sen- sor. To change the degree format for all tem- peratures displayed on the main unit, set on the back of the main unit to the °C/°F desired setting.
  • Page 22: Reading The Temperature And Humidity Trend Display

    READING THE TEMPERATURE AND HUMIDITY TREND DISPLAY The main unit displays the current tem- perature and humidity trend as rising, steady, or falling. The trend is based on the average temperature measured at the selected channel’s remote sensor within the last 30 minutes. Note: If appears, the HHH°...

  • Page 24: Reading The Signal Status

    READING THE SIGNAL STATUS The main unit displays the signal re- ceived status (directly above the CHAN- number). If there are no arcs above the channel number, then the main unit is not receiv- ing a signal. One to three arcs indicate the main unit is searching for and/or re- ceiving a signal (from the selected chan- nels’s remote sensor).
