This chapter includes safety information and legally required disclosures.
Warning: Please adhere to the following safety precautions at all times. Failure to
do so may result in harm to persons or property.
Safety considerations
l Follow electrostatic precautions whenever the SDR-2400/SM-SDR-2400 is installed. To prevent
malfunction or damage which may be caused by electrostatic discharge, the SDR-2400/SM-SDR-
2400 should be grounded.
l Before touching components or connecting/disconnecting cables, the installer should touch a
metal object to dissipate body charge.
l Make sure the power is turned off and the power cord is disconnected whenever the SDR-
2400/SM-SDR-2400 is being installed or moved.
l Do not apply voltage levels that exceed the specified voltage range. Doing so may cause fire
and/or electrical shock.
l Do not open the chassis when the SDR-2400/SM-SDR-2400 is running: Electric shocks can occur.
l If considerable amounts of dust, water, or fluids enter the SDR-2400/SM-SDR-2400, turn off the
power supply immediately, unplug the power cord, and contact the distributor or sales rep-
resentative.
l Do not drop the SDR-2400/SM-SDR-2400 onto a hard surface.
l Do not use the SDR-2400/SM-SDR-2400 in a site where the ambient temperature exceeds the
rated temperature.
ESD notice
To prevent malfunction or damage to this product, which may be caused by electrostatic discharge
(ESD), the radio should be properly grounded at the time of installation. In addition, the installer or main-
tainer should follow proper ESD precautions, such as touching a bare metal object to dissipate body
charge prior to touching components or connecting/disconnecting cables.
