D-Link VOIP TA DVG-5112S - Manual (Page 56)

• When connecting or disconnecting power to hot-pluggable power supplies, if offered with your
device, observe the following guidelines:
• Install the power supply before connecting the power cable to the power supply.
• Unplug the power cable before removing the power supply.
• If the system has multiple sources of power, disconnect power from the device
by unplugging all power cables from the power supplies.
Servicing/Disassembling
• Do not service any product except as expressly set forth in your system documentation.
• Opening or removing covers that are marked with the triangular symbol with a lightning bolt may
expose you to an electrical shock. Only a trained service technician should service components
inside these compartments.
• To reduce the risk of electrical shock, never disassemble this device. None of its internal parts are
user-replaceable; therefore, there is no reason to access the interior.
• Do not spill food or liquids on your system components, and never operate the device in a wet
environment. If the device gets wet, see the appropriate section in your troubleshooting guide or
contact your trained service provider.
• Use the device only with approved equipment.
• Move products with care; ensure that all casters and/or stabilizers are firmly connected to the
system. Avoid sudden stops and uneven surfaces.
Environment
• Do not use this device near water (e.g. near a bathtub, sink, laundry tub, fish tank, in a wet
basement or near a swimming pool).
• Do not use this device in areas with high humidity.
• This device must not be subjected to water or condensation.
• Keep your device away from radiators and heat sources. Also, do not block cooling vents.
Cleaning
• Always unplug the power before cleaning this device.
• Do not use liquid or aerosol cleaners of any kind. Use only compressed air that is recommended for
electronic devices.
• Use a dry cloth for cleaning.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge
static electricity from your body before you touch any of the electronic components, such as the
microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.
You can also take the following steps to help prevent damage from electrostatic discharge (ESD):
1. When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the
component in your system. Just before unwrapping the antistatic packaging, be sure to
discharge static electricity from your body.
2. When transporting a sensitive component, first place it in an antistatic container or
packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads,
workbench pads, and an antistatic grounding strap.
