Testing Stored Emergency Numbers
If you store an emergency service's number (police department, fire depart- ment, 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 ex- plain the reason for your call.

•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 can make or answer calls as usual using the keys on the handset.
You can use a handset holder (available from your local RadioShack store) to hang the handset on your belt for great- er convenience.
When you finish using the headset, dis- connect it from the handset.
