Chain-Dialing Service Numbers

For quick recall of numbers for special services (such as alternate long distance or bank by phone), store each group of numbers in its own memory location. To use the stored special service information, dial the service’s main number first. Then, at the appropriate place in the call, press MEM and enter the memory location number (0–9) for the stored information.

Testing Stored

Emergency Numbers

If you store an emergency service’s number (police department, fire department, ambulance) and you choose to test the stored number, make the test call during the late evening or early morning hours to avoid peak demand periods. Also, remain on the line to explain the reason for your call.

USING A HEADSET

You can talk with hands-free convenience using an optional headset that has a 3/32-inch (2.5-mm) plug. Contact your local RadioShack store for a suitable headset.

To connect the headset, open the rubber cover on the side of the handset, then insert the headset’s plug into the jack.

Notes:

•Connecting a headset disconnects the handset’s earpiece and microphone.

•VOLUME on the handset also controls the connected headset’s volume.

•If you place the handset on the base to recharge it while the headset is connected, be sure the handset seats properly.

•With a headset connected, you make or answer calls as usual using the keys on the handset.

•You can use an optional handset holder (available from your local RadioShack store) to hang the handset on your belt for greater convenience.

•When you finish using the headset, disconnect it from the handset and close the rubber cover to protect the jack.
