Installing the CS 750 (return to top)

The CS 750 is a single line device that can be installed on any type of modular or non-modular system that consists of one or more lines, with one or more phones. A modular system consists of phone cables that can be connected and disconnected from a telephone device. A non-modular system consists of cables that are hard-wired to the telephone device and cannot be disconnected from the equipment. A telephone installer may be required to install the CS 750 on a non-modular system.
NOTE: Many offices have a KSU or PBX phone system. The CS 750 works with either of these systems. Simply follow the appropriate installation instructions provided in "Installation on a telephone system."
Ports on the CS 750 (return to top)
The rear panel of the CS 750 includes five (5) modular ports and a power input port, as shown:

1. Connect the provided modular line cord from a standard telephone (wall) jack to this port. The CS 750 will transfer all voice calls to the TAD and PHONE ports simultaneously.
2. Connect your Telephone Answering Device (TAD) or integrated phone/answering machine to this port. The CS 750 will transfer all voice calls to the TAD and PHONE ports simultaneously.
 4. Connect your fax machine to the FAX port. A computer modem or fax/modem can also connect to this port in lieu of a fax machine.
3. Depending on the installation, a single line phone, an integrated phone/answering machine, multiple phones, or a telephone system (KSU or PBX) can be connected to this port.
5. A computer modem or fax/modem can connect to the MODEM port to enable the CS 750 to transfer a modem call with the appropriate transfer codes.
Placing the CS 750 (return to top)

The CS 750 can be placed on either a flat surface, or mounted on a wall (connectors not included) with the connected telephone line cords above or below the unit.
NOTE: If you place the CS 750 on a flat surface, do not place it in close proximity to any peripheral equipment (approximately 2 to 3 feet away from all electronic equipment).
Connecting the CS 750 (return to top)

This section explains how to install the CS 750 in most phone configurations that appear in a home or office. You can install the CS 750 into one of the following phone configurations:

 a single telephone line

 a telephone system

Installation procedures for each of these configurations are provided in the following sections.

To perform the installation procedures in the following sections, you may need the following equipment:
 

telephone cables to connect the CS 750 to your telephone (wall) jack.
  

extension cables--required if the connecting equipment is not located near the CS 750.
  

additional telephone cables -- typically supplied with equipment by the manufacturer. You need additional telephone cables for as many pieces of equipment as you intend to connect to the CS 750. If the equipment manufacturer does not provide the required cables, you can purchase them at a consumer electronics store.
Installation on a single telephone line (return to top)

The following diagram shows a complete installation for a telephone line. While the connections to the telephone (wall) jack may be different for other types of phone systems, the connections to the CS 750 remain the same for all phone configurations.
1.

Plug one end of the provided modular line cord into the LINE-IN port on the CS 750. Plug the other end of the modular line cord into the telephone (wall) jack.

 4.

To connect a phone, plug one end of a modular line cord into the PHONE port on the CS 750.
2.

Plug the small end of the AC power cord provided with the CS 750 into the power input port labeled "12 VAC" on the CS 750. Plug the adapter into a standard AC outlet.

The green LED flashes rapidly for a few seconds when power is applied and then remains illuminated, indicating its ON status.

 5.

To connect a fax machine, plug one end of a modular line cord into the FAX port on the CS 750.

Set the fax to answer on 1 ring.
3.

To connect an answering machine, plug one end of a modular line cord into the TAD port on the CS 750.

 6.

To connect a telephone device such as a computer modem, plug one end of a modular line cord into the MODEM port on the CS 750.

Set the modem to answer on 1 ring.
NOTE: To connect a Caller ID device with the CS 750, simply plug the Caller ID into the telephone (wall) jack, then plug the CS 750 into the Caller ID.
The CS 750 is only compatible with Caller ID if it is set to answer calls on the second ring.

To set the CS 750 to answer calls on the second ring, perform the following steps:

1.

Take the phone in the PHONE port off-hook

2.

Press # * 402 * (three beeps) *

3.

Hang up the phone
NOTE: Caller ID is a service provided by your local telephone company. (Service activation required.)
Installation on a telephone system (return to top)

A telephone system is common in a medium or large office arrangement in which calls are coming in on 2 or more telephone lines and can be routed to any number of extensions. The system typically has features like call holding, music on hold, conference calling, and intercom paging.

The diagram shows telephone devices connected to the CS 750 for a telephone system; follow the same procedures if you have a mini-telephone system in your home or small office. For the CS 750 to operate properly, it must be "in front" of the telephone system. In other words, it must connect directly to the incoming telephone line. Connect the other equipment as previously shown.

All equipment on that line (telephone system, fax, computer modem, and so on) must connect directly to the CS 750.
CAUTION: You should be familiar with telephone wiring to complete this installation. If you have any questions or are not confident that you can complete this installation procedure, contact the Customer Service Center in the "Warranty" section of this guide or a professional installer for further instructions.

Do not plug the CS 750 into a telephone system phone jack. You may damage your phone system.
