A:AnswerNot that I'm aware of. You can read the manual by going to their website and getting a PDF of the entire manual which shows all features. You can do that for almost any product.
A:AnswerHi! If you are referring to the ringtone, you can select different ringtones for different groups only, not for specific callers, only if you place those numbers in a group and assign a specific ringtone to that group. The main base unit has Bluetooth, therefore it will connect to a cell via Bluetooth only. -A
A:AnswerHi! There is an English only option for this phone, and a second option for Spanish. You can select English only and the phone will stay like that unless you manually change it to Spanish. You can definitely put the phone on silent, that turns off the ringer. -A
A:AnswerHi! Sorry to hear about the troubles. Yes, for this model you can turn off the ringer, both on the base and the handsets. If you do not have a technical issue with the phone, you can try turning the ringer off by pressing and holding 0 or go to ringer settings and turn it off! -A
A:AnswerHi James, thank you for your question! We recommend using the batteries HHR-4DPA, they are tested with our phones and work amazing. The batteries will last in continuous use 10 hours max., and not in use (standby) 5 days max. -A
