Note: 

• Do not place the clock in direct sunlight as this 

will give you an inaccurate temperature reading. 

Replacing Batteries: 

• We recommend using high quality batteries for 

the best product performance. 

• Heavy duty or rechargeable batteries are not 

recommended. 

•The outdoor sensor requires lithium batteries in 

low temperature conditions. Cold temperatures 

would cause alkaline batteries workimproperly. 

• Do not mix old and new batteries. Do not mix 

alkaline, standard, and rechargeable batteries. 

Low Battery Indicator: 

If the low battery indicator is displayed on the 

LCD for either the outdoor sensor or the display 

unit, immediately change the batteries to prevent 

disruptions in communications of the devices.
