Telephone Operation

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.
