Q: Is there a way to sync the phone books on my two handsets? Q: When I pick up a call on one handset, the other handset still displays it as a "missed call". Q: why I can not get 300m range for my adp5000? Q: Why can't I hear the conversation from the other handset? Q: How far away from the base can I talk on my handset? Q: Can I use "handset 2" to make a call while "handset 1" is being used? Q: How do I transfer calls from one handset to another? Q: Why didn't the DECT 6.0 cordless phone copy all the numbers from my mobile phone SIM card? Q: Why can't I register the handset to the base after I followed the instructions? Q: I am interested in purchasing extra handsets to connect to the base I already have. Do you sell just the handsets?
