z Before accessing the DIP switches, turn off the power and make sure that none of
the LEDs on the circuit board are lit. Attempting to access the DIP switches with
any LED lit could result in an electrical shock due to electricity remaining in the
circuit.
Be sure to check the DIP switch settings whether or not you want to change the factory default settings.
After changing any DIP switch setting or connector, you have to turn the power off and back on for the
new setting to take effect.
When you want to reset the outdoor unit power supply, turn off the power and make sure that none of the
LEDs on the circuit board are lit before turning back on the power. An attempt to reset the power supply
with any LED lit may fail due to electricity remaining in the circuit.
