INSTALLATION

SELECTING A LOCATION

You can place the phone on a desk top or table, or mount it on a wall. Select a location that is:

•near an AC outlet

•near a telephone line jack

•out of the way of normal activities

•away from electrical machinery, electrical appliances, metal walls or filing cabinets, wireless inter- coms, alarms, and room monitors

•away from other cordless phones

The base’s location affects the hand- set’s range. If you have a choice of several locations, try each to see which provides the best performance.

MOUNTING/CONNECTING THE PHONE

To use both of the ET-596’s lines, you must connect it to two separate tele- phone lines. Each of these lines must have its own phone number. If you do not have two telephone lines, contact your phone company to get a second line.

You can connect your telephone to a 2-line modular telephone jack using the supplied 2-line modular cord.

Note: Two-line and single-line modu- lar cords look alike, but are wired dif- ferently. To use the ET-596’s two lines, use only the supplied 2-line modular cord to connect to a 2-line modular jack.

Or, you can connect your telephone to two separate 1-line modular telephone jacks using the supplied modular cord and another 1- or 2-line modular cord (such as RadioShack Cat. No. 279- 356, not supplied).

Note: You can also use the ET-596 with a single 1-line modular jack.

If your phone wiring does not have a modular phone jack, you can:

•Update the wiring yourself, using jacks and adapters available at your local RadioShack store

•Have the phone company update the wiring for you

Note: The USOC number of the jack to be installed is RJ14C for a two-line baseboard jack or RJ14W for a two- line wall-plate jack.

Caution: The supplied RadioShack adapter was designed specifically for your ET-596. Use only the supplied adapter.
