CONNECTING THE

BATTERY

Your phone comes with a recharge- able nickel-cadmium battery installed. However, before you use the phone for the first time, you must connect the battery and charge it for about 24 hours.

Follow these steps to connect the bat- tery.

1.While lifting up on the battery compartment cover’s latch on the back of the handset, pull the cover up to remove it.

2.Pull and lift the front tab on the battery restraining strap to remove it.

3.Connect the battery’s wires to the battery connector inside the com- partment, then insert the battery.

Note: The battery’s connector fits into the connector inside the com- partment only one way. Do not force it.

4.Replace the battery restraining strap and the cover.

After you connect the battery, you must connect power, then charge the battery.

CONNECTING POWER

Caution: You must use a 120V AC/9V DC adapter that delivers at least 150 milliamps. Its plug must correctly fit the phone’s POWER 9V DC jack. The sup- plied adapter meets these require- ments. Using an adapter that does not meet these requirements could dam- age the phone or the adapter.
