) is in the
ON or SNZ (snooze) position, the display is automatically illuminated with a dim light eight hours before the alarm
time is reached.
THERMOMETER AND HYGROMETER FUNCTIONS
A built-in sensor measures temperature and humidity, and shows the measured value on the display.
The readout from the temperature sensor can also be switched between Celsius (°C) and Fahrenheit (°F).
Temperature Measurements
The temperature display shows “LO” for temperatures below –19.9°C (–3.8°F) and “HI” for temperatures above
49.9°C (121.8°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).
Switching between Celsius and Fahrenheit causes current high temperature/humidity and low temperature/
humidity memory contents to be cleared.

Humidity Measurements
The humidity display shows “LO” for humidity below 10% and “HI” for humidity above 90%.
Whenever the current temperature is outside the range of 0°C to 49.9°C, the humidity display will show “– –”.
Daily High Temperature/Humidity, Low Temperature/Humidity Memory
The clock remembers the highest and lowest temperature and humidity readings for the current 24-hour day.

BATTERY REPLACEMENT
Replace batteries whenever the display of the clock becomes dim and difficult to read.
1. Open the battery compartment cover as shown in the illustration.
2. Remove all of the old batteries.

directions. If you load batteries incorrectly, they can burst and damage the clock.
4. Press the RESET button (
6

5. Replace the battery compartment cover.
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.
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.
