Heat Index/Dew Point: Press HEAT/DEW once for Heat Index, twice for Dew Point.
Backlight: Adjustable (HI-LOW-OFF) when using AC power. With battery power only, backlight comes on for 10 seconds when pressed.
MIN/MAX Values: Automatically resets daily at midnight. Press ▼ to view minimums, hold ▼ for 5 seconds to reset. Press ▲ to view maximums, hold ▲ for 5 seconds to reset.
Outdoor Sensor Search: Hold HEAT/DEW for 3 seconds. The signal icon animates until a signal is received or for 3 minutes.
Temperature/Humidity Trend Indicators: Updates every 30 minutes or less, showing if temperature (2°F/1°C) and humidity (3% RH) have risen, fallen, or not changed in the past 3 hours.
WWVB Radio-Controlled Time Search: Press TIME SET to start/stop a manual search. The WWVB icon flashes during search and is solid when connected. Searches automatically at UTC 7:00, 8:00, 9:00, 10:00, and 11:00.

Maintenance Features:

Low Battery Icon: Indicates low battery for the station or sensor. Replace batteries next to outdoor temperature (sensor) or indoor temperature (weather station).
Position Outdoor Sensor: Mount on a north-facing wall or in a well-shaded area, preferably under an eave or deck rail. Maximum transmitting range is over 300 feet in open air.
Care and Maintenance:
- Do not mix old and new batteries, or different types (Alkaline, Standard, Lithium, Rechargeable).
