If the battery pack gets completely discharged, the ET-551 loses the security access-protection code. To reset the code, place the hand- set on the base and charge the battery pack.

The supplied battery pack should last about a year. When the bat- tery pack loses its ability to fully recharge, order a replacement battery pack from your local Ra- dioShack store (see “Replacing the Battery Pack” on Page 19).

SETTING THE DIALING MODE

Set T/P (Tone/Pulse) on the back of the base for the type of service you have. If you are not sure which type you have, do this test.

If the dial tone stops, you have touch-tone service. Leave T/P set to T.

If the dial tone continues, you have pulse service. Set T/P to P.

TURNING THE RINGER ON OR OFF

To turn off the ringer, set RINGER on the base to OFF. To turn on the ringer, set it to ON.
