Link Wireless Telephones and Accessories User Guide

Do not attempt to open or repair a defective Battery Pack.

Flashing red/green—there is a problem with either the Battery Pack or Link Quick Charger. It may mean the Battery Pack being charged is too hot or too cold. Allow the Battery Pack to stabilize at room temperature and try again. If the Battery Pack will not charge, do not continue to charge the Battery Pack. Dispose of it properly and do not attempt to use it in the handset. Do not attempt to open or repair a defective Battery Pack. If several different Battery Packs cause the charger to show a flashing red or red/green LED, the charger may not be working properly. To verify this, substitute another Link Quick Charger and repeat the operation that caused the failure. If the same Battery Pack lights a green LED when inserted in a different charger, the Link Quick Charger is faulty. Contact your service representative for assistance.

Flashing yellow—the Link Quick Charger is testing and conditioning the Battery Pack. This test/condition mode is automatically started every 11th cycle of the charger. Testing the NiCd standard Battery Pack takes approximately four hours; testing the NiMH high- capacity Battery Pack takes approximately eight to ten hours. To manually start the test, press the MODE button. To stop the test, press the MODE button. However, it is highly recommended that the test be allowed to complete.

Battery Pack bins If a handset is to be used during the recharging cycle, fully charged Battery Packs must always be available. Therefore, it is recommended that a bin is available to collect discharged Battery Packs and a second bin for charged Battery Packs. Users can quickly replace their discharged Battery Pack with a charged one. An assigned person can recharge the Battery Packs and move them to the charged bin as they are recharged. It is also recommended that the bins be non-metallic and clearly labeled to identify whether they are intended for charged or discharged Battery Packs.
