We have the above telephone with two handsets but the volume is very low on one of tem and we have lost the manual and cant adjust it. Anyone either got a manual or can tell me what to do, my friends think I am not speaking to them, but I simply can hear them! Thanks in advance.

To adjust the handset volume you need to press up on the 4 way button (top middle of the buttons) DURING a call
