THERMOMETER FUNCTIONS
• A built-in sensor measures temperature and shows the measured value on the display. The readout from the
temperature sensor can also be switched between Celsius ( °C) and Fahrenheit (°F).
• 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 40.1°C (104°F), note that such
readings are actually outside the guaranteed temperature range of this clock.
Switching between Celsius and Fahrenheit
• Slide the °C / °F switch (6) to specify Celsius (°C) or Fahrenheit (°F) as the temperature unit.
HYGROMETER FUNCTION
• A built-in sensor measures humidity and shows the measured value on the display.
• The humidity display shows “LO” for humidity below 10% and “HI” for humidity above 95%.
BATTERY REPLACEMENT
Replace batteries whenever the display of the clock becomes dim and difficult to read.
1. Pressing down lightly on the battery compartment cover, slide it downwards and remove it.
2. Remove all of the old batteries.
3. Load a full set of new batteries. Make sure that their positive (+) and negative (–) ends face in the correct
directions. If you load batteries incorrectly, they can burst and damage the clock.
4. Replace the battery compartment cover.
5. Press the RESET button (3). Be sure to press the RESET button (3) after replacing batteries.
Battery precautions
• Keep batteries out of the reach of small children. If a battery is accidentally swallowed, contact your physician
immediately.
• 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 clock.
• Should batteries ever leak while in the clock, 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 clock lose some of their power during transport and storage.
