Operation Range - Daikin FVQ71CVEB Operation Manual

Never touch the internal parts of the remote
controller.
Do not remove the front panel. Touching certain
internal parts will cause electric shocks and
damage to the unit. Please consult your dealer
about checking and adjustment of internal parts.
Do not leave the remote controller wherever
there is a risk of wetting.
If water gets into the remote controller there is a
risk of electrical leakage and damage to elec-
tronic components.
