Cordless phones come with up to five handsets each will need to be properly adjusted. You may need to set the main handset to synchronize with the base unit plugged into the telephone wall jack and assign special configuration numbers to the other handsets in order to properly identify each one within a specified location. One handset left in the turned on mode may make it impossible to place calls with the any of the other handsets. This will continue until either the battery dies or fails on the handset or the phone is switched off and replaced in its charger for charging again. Synchronize the main handset by pressing the MENU button on the handset, then pressing the down button IN order to select the number you wish to assign to that handset. Repeating this process if you have already done so will greatly decrease the level of errors experienced with panasonic phones.
