AFETY

To ensure your safety when servicing and installing this equipment, please
take the following precautions:

Be careful when installing or modifying telephone lines.
Dangerous voltages can be present. It is unsafe to install
telephone wiring during a lightning storm.

Always disconnect all telephone lines and power connections
before servicing or disassembling this equipment. For
performance and safety reasons, only power supplies listed
for use with telephone equipment by a locally recognized
organization should be used with PairGain equipment. All
wiring external to the product should follow the local wiring
codes.

Walte Vorsicht beim Installieren oder Ändern von
Telefonlinien. Gefährliche Spannungen könnten anliegen. Es
ist nicht sicher während eines Gewitters Telefondräte zu
installieren.

Bevor Wartung oder Auseinandernehmen des Gerätes
müssen immer alle Telefon- und Netzkabel ausgezogen
werden. Aus Leistungs- und Sicherheitsgründen sollten nur
Netzteile die für Telefongeräte zugeschnitten und von einem
renommierten Geschäft vertrieben werden mit PairGain
Geräten verwendet werden. Alle externen
Verdrahtungsarbeiten sollten nach den hiesigen
Elektrizitätsvorschriften ausgeführt werden.
