THERMOMETER FUNCTIONS
MAX/MIN TEMP. button (7)
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.
Main unit high temperature and low temperature
Sub-unit high temperature and low temperature
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.
