INSTALLING A 9V

BATTERY

To protect your messages and programmed information during a power failure or to replace the battery when “Lb” appears in the display:

1Turn the TC-540 over and remove the battery cover.

2Install a 9V alkaline battery. Make sure the battery is connected correctly.

3Replace the cover. The battery connection will not be activated until the cover is replaced.

TWO-LINE

INSTALLATION

Two-line installations may require a two-line T-Adapter for your machine to operate correctly. The T-Adapter allows you to connect your machine to Line 1 or Line 2. The TC-540 will only answer one line.

MULTI-LINE

INSTALLATION

Installations with more than two lines, such as a business phone system, may require a separate RJ11 jack for answering machines. Please contact your telephone equipment provider for additional information.

You can use the TC-540 as an extension phone on a business phone system, but some systems will require that you install an A+A1 Adapter to light the in-use indicator on the receptionist’s console. See the accessory order form on the last page of this owner’s guide to order an A+A1 Adapter.
