A quick start guide

Rated 5 out of 5 by from This phone is very easy to set up, it will only take a few moments to enter the time and date. The BT8500 will synchronize all handsets together so once the time and date is set on one phone there will be no need to set the remaining two handsets, also any contacts entered onto one handset can be accessed by all. The sound from the handsets are loud and clear so you will never have difficulty hearing who is on the line. A great feature on the BT8500 is the nuisance blocker, you will always know who is calling before talking to the person on the line, you will be given a choice to accept the call, block the call or send the call to the answer machine

I currently have a four landline phones, including one in the bedroom which I only use occasionally. Can you mix a 4th landline phone with three BT 8500's, and if so will the call blocker function still work properly?

Asked by: alanR
You can plug the Master unit of this kit into any of your land line sockets. The call blocker functionality will only work if the 8500 kit answers the call.

Is it possible to adjust the volume on the calls which are not on your selected list and which require callers to say who they are, etc. The calls which I receive in this category are very faint and hardly able to be heard.

Asked by: Scothern20
You can adjust the caller volume after answering or go to loudspeaker. Page 27 of your instructions details how to do this.
