CAUTION
• Never use chemicals or organic solvents such as benzene and
thinner to clean the housing. Do not apply insecticide to the
QS20H.
Doing so could result in a marred or cracked housing, electrical
shock or fire.
• When disconnecting the AC adapter from the wall socket, hold the
AC adapter body not the power cable.
The power cable may be broken, resulting in a burnt AC adapter,
electrical shock, or fire.
• During electrical storm activity, always unplug the AC adapter
from the wall socket.
Exposure to power surges could result in a damaged QS20H or
fire.
• When taking care of the QS20H, unplug the AC adapter from the
wall socket for safety.
Failure to do so could result in an electrical shock.
• If the interface cable is damaged (e.g., exposed or broken lead
wires), stop using it and contact your nearest dealer.
Failure to do so could result in a fire or electrical shock.
