Thermal Management

The POC-W243 terminal cover features vent holes that function as air inlets and out-
lets that transfer heat from inside the equipment to the cooler air outside. Do not
block the holes/vents with any material.
During operation, it is normal for the metal heatsink at the rear of the device to
become warm. The metal heatsink functions as a cooling surface that transfers heat
from inside the equipment to the cooler air outside. Do not block the heatsink with
any material.
Warning! Do not place the POC-W243 terminal on a pillow or other soft material
when powered on because the material may block airflow and cause the
device to overheat.
