INSTALLATION OPTIONS
Although you can use your 2-line cordless telephone with a single phone line, you must have two lines (separate phone numbers) to use a two-line system. The following diagrams show two possible systems:
A Single-Line on a Modular Jack
If you want to only connect one line, plug one of the telephone line cords into the L2 jack and into a single modular phone jack. Your phone will only use line 2 with this connection. Line 1 will not be used.
Two Lines on Single Modular Jack
One type of two-line phone system uses a single RJ14 modu- lar jack which contains both phone lines. Connect the phone cord to the L1 OR L2 jack.
You must use a 4-conductor telephone line cord like the gray one packed with your unit.
