BATTERY INSTALLATION
NOTE: When the temperature falls below freezing point 32F° (0C°), battery voltage will
drop which may result in reduced the transmission range. For optimum performance in
cold weather conditions, we recommend using lithium batteries.
NOTE: Install the batteries before mounting the remote sensor.
• Remove the screws from the battery compartment with a small Phillips screwdriver (not
included).
• Install 2 “AAA” size batteries (not included) matching the polarities shown in the battery
compartment.
• Replace the battery compartment door and secure the screws.
• Secure the remote sensor in the desired location.
MOUNTING
