When you are using an external telephone, the LCD shows Telephone.

Operation from extension telephones

If you answer a fax call on an extension or an external telephone plugged into the correct socket on the machine, you can make your machine take the call by using the Remote Activation Code. When you press the Remote Activation Code l 5 1, the machine starts to receive the fax.

If the machine answers a voice call and pseudo/double-rings for you to take over, use the Remote Deactivation Code # 5 1 to take the call at an extension telephone. (See F/T Ring Time (Fax/Tel mode only) on page 34.)

Telephone and External devices

If you answer a call and no one is on the line:

You should assume that you're receiving a manual fax.

Press l 5 1 and wait for the chirp or until the LCD shows Receiving, and then hang up.

Note

You can also use the Fax Detect feature to make your machine automatically take the call. (See Fax Detect on page 35.)

Using extension telephones (For U.K. only)

Your premises may already be wired with

plan to add extension telephones to your line,

as well as your machine. While the simplest arrangement is a straightforward parallel connection, there are some problems with this arrangement, the most obvious of which is inadvertent interruption of a facsimile transmission caused by someone picking up an extension telephone to make an outgoing call. Also, Remote Activation Code may not operate reliably in such a simple configuration.

This machine may also be set to make a delayed transmission (i.e. a transmission at a pre-set time). This pre-set job may coincide with someone picking up an extension handset.

These problems can easily be eliminated, if you arrange modification of your extension wiring circuit, such that extension devices are connected ‘downstream’ of your machine in a master/slave configuration (see fig. 2). In this configuration the machine can always detect whether a telephone is in use. Thus it will not attempt to seize the line during that time. This is known as ‘telephone off-hook detection.’

The inadvisable configuration is shown in figure 1, and the recommended master/slave configuration is shown in figure 2.
