This equipment complies with Part 68 of the FCC Rules. A label is attached to this equipment that contains, among other information, the FCC registration number and ringer equivalence number (REN) for this equipment. If requested, this information must be provided to the telephone company.
This equipment uses the following USOC jacks: RJ-11C
The REN is used to determine the quantity of devices that may be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to the line, as determined by the total RENs, contact the telephone company to determine the maximum REN for the calling area.
If this equipment causes harm to the telephone network, the telephone company will notify you in advance that temporary discontinuance of service may be required. If advance notice is not practical, the telephone company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the equipment. If this happens, the telephone company will provide advance notice in order for you to make the necessary modifications in order to maintain uninterrupted service.

NOTICE: The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe systems, if present, are connected together. This precaution may be particularly important in rural areas.
CAUTION: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.
NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5.
Este módem ha sido probado y certificado según los estándares de seguridad siguientes y está diseñado para ser utilizado en un equipo informático que ha sido probado y certificado según estos estándares u otros equivalentes:
Una marca con el símbolo 
indica que este equipo cumple las directivas de EMC Directive 89/336/EEC, Low Voltage Directive 72/23/EEC modificada por la 93/68/ECC, y la Telecom Terminal Equipment and Satellite Earth Stations Directive 98/13/EEC. Esta marca indica, por tanto, que este equipo cumple o supera los siguientes estándares técnicos:
ADVERTENCIA: Aunque este equipo puede utilizar la desconexión por bucle o la señalización DTMF, sólo el rendimiento de ésta está sometido a una normativa para su correcto funcionamiento. Por tanto, se recomienda especialmente configurar el equipo para que utilice la señalizació DTMF para acceder a servicios de emergencia públicos o privados. La señalización DTMF proporciona también un establecimiento de llamada más rápido.
Este equipo ha sido aprobado por la Council Decision 98/482/EEC--"CTR 21" for Pan-European single terminal connection to the Public Switched Telephone Network (PSTN). No obstante, debido a las diferencias entre los PSTN proporcionados en cada país, la aprobación no asegura por sí sola un funcionamiento satisfactorio en todos los puntos terminales PSTN. En caso de que aparezcan problemas, debe contactar con el proveedor del equipo en primer lugar.
El estado de seguridad de los puertos de este módem es el siguiente:
Puerto de interfaz de línea - TNV
Conector de bus PCMCIA al PC - SELV
Tenga en cuenta que sólo los puertos SELV deben conectarse entre sí, al igual que los puertos TNV. La interconexión de puertos con distintos estados de seguridad puede invalidar la aprobación. Si tiene dudas para realizar una conexión de este tipo, solicite la asistencia de un técnico cualificado.
El usuario debe asegurarse de que el módem, el host y los aparatos auxiliares de éste reciban alimentación comprendida en el rango de voltaje admitido.
El módem tiene los siguientes requisitos de alimentación: +5 V a 350 mA.
El usuario debe tener en cuenta que la aprobación se refiere al módem y no al host.
Cuando el módem se suministre con un equipo host, también se deben incluir las instrucciones del usuario del módem. En caso contrario quedará invalidada la aprobación del módem.
Consulte al distribuidor o responsable del mantenimiento del módem si tiene dificultades de funcionamiento, no al operador de red.
Not all phones connected to the phone port will respond to incoming ringing. Do not report this as a fault unless the same phone will not respond to ringing when connected to a standard phone socket.
This equipment shall not be set up to make automatic calls to the Telecom 111 Emergency Services.
The grant of a Telepermit for a device in no way indicates Telecom acceptance of responsibility for the correct operation of that device under all operating conditions. In particular, higher speeds at which this modem is capable of operating depend on a specific network implementation which is only one of many ways of delivering high quality voice telephony to customers. Failure to operate should not be reported as a fault to Telecom.
In addition to satisfactory line conditions a modem can only work properly if:
a) it is compatible with the modem at the other end of the call and,
b) the application using the modem is compatible with the application at the other end of the call - e.g. accessing the Internet requires suitable software in addition to a modem.
This equipment should not be used in a manner which could constitute a nuisance to other Telecom customers.
Some parameters required for compliance with Telecom's PTC Specifications are dependent on the equipment (PC) associated with this modem. The associated equipment shall be set up to operate within the following limits for compliance with Telecom specifications:
a) There shall be no more than 10 call attempts to the same number within any 30 minute period for a single manual call initiation
b) The equipment shall go back on-hook for a period of not less than 30 seconds between the end of one call attempt and the beginning of the next.
c) Automatic calls to different numbers shall be not less than 5 seconds apart.
d) When used in the Auto-Answer mode, the S0 register must be set with a value between 2 and 5. This ensures:
i. A person calling your modem will hear a short burst of ringing before the modem answers. This confirms that the call has been successfully switched through the network.
ii. Caller identification information (which occurs between the first and second ring cadence) is not destroyed.
The code for Call Waiting disable is *52 on the Telecom New Zealand telephone network.
This is a Class B product based on the standard of the Voluntary Control Council for Interference from Information Technology Equipment (VCCI). If this is used near a radio or television receiver in a domestic environment, it may cause radio interference. Install and use the equipment according to the instruction manual.
