10.6 Charging the Handset’s Battery Pack You must fully charge the rechargeable nickel-cadmium battery pack before using your digital wireless telephone for the first time. This means that you should allow the unit to charge with - out interruption for 8–10 hours. If you do not intend to use the handset for more than a day, ei - ther store the handset on the charger or take the battery pack off the handset to avoid draining the battery too low. 1. Place the handset on the base unit. NOTE: The unique design of your digital wireless telephone allows you to place the handset on the base unit either face down or face up, with or without the belt clip attached. The battery pack in the handset automatically recharges in either position. Please note that the telephone’s buttons are inoperative while the handset is on the charger. 2. Make sure theCHARGELED turns on. If theCHARGE LED does not turn on, check to see that the AC adapter is plugged in, and that the handset is making good contact with the base unit. NOTE: Occasionally, use your handset until the display shows the low battery indication. As soon as you see this indication, discon- tinue further use, and recharge or replace the battery pack.

10.7 Charging Extra Battery Packs The digital wireless telephone’s base unit is equipped with a spare battery charger for charging an extra battery pack; how - ever, for quickest charge, always use the base unit’s handset cradle charger. NOTE: If you keep a spare battery pack in the spare battery charging compartment, occasionally alternate that battery pack with the one that is in the handset. After you install a replacement battery pack in the handset, allow that battery pack to charge without interruption for 8–10 hours with the handset in the base unit’s cradle. 1. Position the battery pack so the inner side is facing toward the top of the base unit. 2. Slide the battery pack into the charging compartment until it clicks into place. Note that the battery pack charging com- partment has a latch that keeps the battery pack in place dur- ing charging. 3. Make sure theBATTERY CHARGELED turns on. If the BATTERY CHARGELED does not turn on, verify that the battery pack is seated into the charging compartment. 4. Allow the battery pack to charge without interruption for 30 hours. 5. When charging is complete, press down on the latch to re- move the battery pack for use. Or, if you don’t need the bat- tery pack immediately, leave it in the charging compartment (the battery pack will not overcharge). Installing The Digital Wireless Telephone 76
10.8 Cleaning The Battery Contacts To maintain a good charge, it is important to clean all charge contacts on the handset and base unit about once a month.

10.9 Attaching The Belt Clip To The Handset Snap the tabs of the belt clip into all four notches on the sides of the handset. Use the belt clip to attach the handset to your belt or pocket for convenient portability. Notice that the belt clip includes a metal loop that you can use to suspend the hand - set from a lanyard if you wish. To remove the belt clip, pry one tab at a time from the notch on the side of the handset. Carefully lift the belt clip off. CAUTION The belt clip is designed to fit snugly onto the handset.

10.10 Testing the Coverage Range Your digital wireless telephone will continue to operate effec - tively as you move some distance away from the base unit. Many circumstances affect the maximum distance that you can travel away from the base unit’s location. Among these are walls and other obstructions that separate you from the base unit’s location. It is a good practice to test the maximum cover - age range that your digital wireless telephone delivers when you first install it so that you will know how far you can travel away from the base unit’s location and still have effective com - munications. To test the coverage location, disconnect the station line cord from the base unit, ensure that the AC adapter is connected to the base unit, lift the handset and verify that the display showsNo Comm, pressTALK, if the handset is in range, the display showsIn rangeand the handset sounds a single tone burst, –or– if the handset is out of range, the display showsNO SER- VICEand the handset sounds three tone bursts, move away from the base unit’s location in an ever-increasing distance while repeating the above test un- til you no longer get anIn Rangedisplay—the maximum distances in any direction at which you can receive theIn Rangedisplay and hear the single tone burst defines the coverage range limits, hang up the handset and reconnect the station line cord to end the range testing. NOTE: If you should wander out of range while on a call, you will lose voice contact with your party but your handset will keep its dis- play and status lights active for approximately 20 seconds. Dur- ing this 20 second time period, you can step back in range and resume your conversation. After this approximate 20 second time period, the handset’s display shows NO SERVICE, the handset sounds three tone bursts, and the telephone drops the call.

* If you isolate improper operation to a defective battery pack, verify that the battery chargers are operating prop - erly. If the battery chargers are operating properly, pur - chase a new battery pack. Since handset and battery warranties differ, do not return your handset for servicing with its battery installed. Refer to the product label or con - sult with your dealer for complete details. Radio interference is not a defect indication. If the situation persists, contact your system administrator. 11.3 Making A Power Reset If you ever experience scrambled displays, link problems, or feature access problems, you may need to execute a power re - set procedure.
