OPERATION

MAKING A CALL

To make a call, lift the handset. Or, if the handset is away from the base, press TALK. On the base, the IN USE indicator lights, and on the handset, the BATT LOW indicator and a LINE indicator (1 or 2, whichever line was di- aled the last time) light.

You can also press LINE 1 or LINE 2 to directly select the line you want to use.

ANSWERING A CALL

To answer a call, simply lift the hand- set. If the handset is away from the base, press TALK to answer the flash- ing line. The TALK/BATT LOW indica- tor, the LINE 1 or LINE 2 indicator on the handset, and the IN USE indicator on the base light.

To help you tell which line is ringing, each line has a distinctive ring tone. To end a call, place the handset on the base or press the handset’s TALK button.

Notes:

•If you press TALK to hang up and the phone does not disconnect, place the handset on the base or press TALK again while holding the handset closer to the base.

•When you receive an incoming call on one line while you are talk- ing on the other, the handset does not ring but you hear the phone

sound a tone through the ear- piece. Place the current call on hold (see “Putting a Call on Hold” on Page 16), then press the line button for the new incoming call.

•If you press the other line’s button without first pressing HOLD, the first call is disconnected.

CHANGING THE

CHANNEL

If you notice interference, static, or noise during a call, you can press CH (channel) to find a clearer channel.

The ET-596 changes to a different channel each time you press CH.

Note: If the handset is too far away from the base, the channel might not change. Move closer to the base and try again.
