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. 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.
