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.
Each press of the MAX/MIN button (8) cycles between screens as illustrated below.
Daily high and low temperature/humidity memory contents are cleared each day at midnight.
Changing the Temperature/Humidity Display Screen
Press of the MAX/MIN button (8). Each press cycles between screens as shown below.

BATTERY REPLACEMENT
Replace batteries whenever the display of the clock becomes dim and diffi cult to read.
1. Open the battery compartment cover as shown in the illustration.
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. 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 fl uid 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.
