• Do not disconnect the RF cable from your PCX5000 while the power to your modem is on.
• Wait at least 10 seconds between disconnecting and reconnecting the PCX5000 with the
AC power adapter.
• Unplug the PCX5000 from the wall outlet carefully, as the AC adapter may be hot.
Use and Maintenance
Unplug Power Before Cleaning - Do not use liquid or aerosol cleaners. Use a damp cloth for
cleaning.
Keep Objects Out of Openings - Never push objects of any kind into the PCX5000 through
openings such as the ventilation holes, as they may touch high voltage circuits and "short-out" parts,
which could result in a fire or electric shock. Never spill liquid on the PCX5000.
Protect From Lightning – Unplug the PCX5000 during a lightning storm, or when leaving it
unattended and unused for a long period. Remove the power adapter from the wall outlet, and
disconnect the cable system. This will prevent damage to the PCX5000 due to lightning and power
line surges. Take care not to touch the metal portion of PCX5000 or cables in a lightning storm.
Service
Do Not Remove Covers - Do not attempt to service the PCX5000 yourself, as opening or removing
covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified
service personnel. Removing the cover will VOID your warranty.
Refer Servicing to Qualified Service Personnel under the Conditions Listed Below
• If the power supply cord or plug is damaged.
• If liquid has been spilled or objects have fallen into the PCX5000.
• If the PCX5000 has been exposed to rain or water.
• If the PCX5000 does not operate normally as per the operating instructions.
• If the PCX5000 has been dropped or the case has been damaged.
• When the PCX5000 exhibits a distinct change in operation, such as the inability to complete its
self-test.
Require Safety Check - Upon completion of any service or repairs to the PCX5000, ask the service
technician to perform the recommended safety checks to verify that the PCX5000 is in a safe
operating condition.
Security Precautions
The PCX5000 provides your home network with the highest level of security. However, no product
can provide you with absolute protection against a determined effort to break into your system. We
recommend using additional security precautions, such as encrypting files and folders to protect
highly valuable or sensitive information.
If you are using the wireless access capability of the PCX5000 and the wireless security options
(encryption and access control) are disabled, an unauthorized user can penetrate your computers
with a remote wireless device. See the section “PCX5000 Wireless Configuration” in this manual
to set the appropriate wireless security parameters.
Range of Wireless Communication
The range of the wireless signal may vary according to the actual radio conditions at the location
where the wireless LAN product is installed. The range of wireless devices may be affected by metal
surfaces and high-density materials such as concrete walls. Range is also impacted due to
“obstacles” in the signal path of the radio that may either absorb or reflect the radio signal.
