Screw tightening
• The screws and bolts must be tightened
with an appropriate tightening torque
according to the material and strength of
the installation area.

impact driver may damage the screws or
cause tightening excessively.

Heater unit
This product is equipped with an internal heat-
er unit for use in cold climates. The heater unit
turns on automatically when the temperature
inside the product drops below around 0 °C
{32 °F}. However, in an extremely low-temper-
ature environment below –30 °C {–22 °F},
snow and frost may not be defrosted from the
dome cover. When using the product in cold
climates, take notice of the ambient and inter-
nal temperatures of the product. When this
product is installed and operated in low tem-
peratures below –20 °C {–4 °F}, normal images
may not be obtained immediately after startup.
In such a case, wait until the internal tempera-
ture of the camera rises (for around 2 hours or
more in temperatures below –20 °C {–4 °F}), turn
the power off once, then turn it back on again.
