Battery precautions

• Be sure to load the batteries with their positive (+) and negative (–) ends facing correctly.
• Never mix old and new batteries, or batteries of different brands.
• Never charge the batteries that come with the product.
• Should batteries ever leak while in the product, wipe out the fluid with a cloth, taking care not to let any get onto
your skin.
• Replace the batteries at least once a year, even if the current batteries are working properly.
• The batteries that come with the product lose some of their power during transport and storage.
THERMOMETER FUNCTIONS
Both the main unit and the sub-unit are equipped with their own temperature sensors. Temperature data measured
by the sub-unit is sent by wireless transfer to the main unit. You can toggle the main unit display between the main
unit temperature reading and the sub-unit temperature reading. This makes it possible to view both the indoor and
outdoor temperature on the main unit display.
Temperature Measurements
• Both the main unit and the sub-unit take temperature measurements every 16 seconds.
• The temperature display shows “LO” for temperatures below –50°C (–58°F) and “HI” for temperatures above
70 °C (158°F).
• Though temperature readings are displayed up to 0°C (32°F) and greater than 41°C (105°F), note that such
readings are actually outside the guaranteed temperature range of this clock.
Switching between Celsius and Fahrenheit
• Push the °C/ °F button (5) to select either Celsius (°C) or Fahrenheit (°F).
