8.This apparatus has been approved for the following facilities:

Connection to direct exchange lines providing DTMF signaling

Connection to compatible PBXs providing DTMF signaling

Operation in the absence of proceed indication, selectable by user

Call progress monitoring functions

Data modem functions

Auto-dialing functions

Auto-answering functions

Any other usage will invalidate the approval of the apparatus, if as a result, it then ceases to conform to the standards against which approval was granted.

All apparatus connected to this modem, and thereby connected directly or indirectly to the British Telecom Public Switched Telephone Network, must be approved apparatus as defined in Section 22 of the British Telecommunications Act of 1984.

Although this equipment can use either loop disconnect or DTMF signaling, only the performance of the DTMF signaling is subject to regulatory requirements for correct operation. It is therefore strongly recommended that the equipment is set to use DTMF signaling for access to public or private emergency services. DTMF signaling also provides faster call set up.

The modem may not be used on extension wiring that makes use of plug pins 1 and 6. If in doubt, advice must be obtained from a competent telecommunications engineer.

Difficulties may occasionally be experienced from other apparatus connected to the BT PSTN via the modem apparatus. Such difficulties may include the following:

difficulty in making calls

problems in telephone conversion being experienced by both parties to the call

Initially, normal operation will be possible. However, changes to or modernization of the network (taking place in the normal course of events) may result in the apparatus being connected to a network service with which it was not designed to be compatible. Failure of the apparatus to work under these circumstances may not be the responsibility of the network operator.

If these difficulties occur, contact your product supplier or your Compaq-authorized reseller in the United Kingdom.

This device is intended for auto-answering of incoming calls. Under normal conditions, callers will be accustomed to calls being answered within 10 seconds, and a majority of callers will abandon calls that are not answered within 45 seconds.
