The volume on one of my handsets is very low. this is the call volume and not the ringer model FF894-2 IQ, southwestern bell, multi handset

Do you mean the Panasonic KX-TGA470 handset? The KX-TGA470 handset is the included handset for several models of Panasonic cordless phone systems, including the KX-TG7732. When the ringer is off, the handset should show a bell with a line through it. To adjust the ring volume, press Menu on that handset when the phone is in standby. (The base and handsets are not in use.) After pressing the Menu button, type # 1 6 0. (Alternatively, use the arrow keys to navigate to Initial Settings and press the soft key for Select. Navigate to Ringer Settings and press Select again. Go to Ringer Volume Handset and press Select once more.) Use the arrow keys to select a value between 0 and 7. 0 will keep the ringer disabled. Press the soft key for Save. Press Off to exit the menu.

You can also adjust the ringer volume on that handset by pressing the Volume Up key while the phone is ringing at the base and other handsets. You can adjust the base ringer volume by pressing the + or - keys when the phone is ringing. Alternatively, press Menu # * 1 6 0 from any handset. Note: this phone system also has a silent mode. Press Menu # 2 3 8 to enable or disable the feature. When this is enabled, the handset will show an icon with several Z's.

You can find the manual on the phone system page: https://shop.panasonic.com/support-only/KX-TG7732S.html . The current link to the manual is ftp://ftp.panasonic.com/telephone/om/kx-tg7731_mul_om.pdf . See pages 23 and 35 for the ringer volume adjustment. See pages 35 and 40 for information on the silent mode.

I hope this helps.

handset, and ten levels on the base. Pressing the

telephone call has ended.
If you press the volume up key when the earpiece is at
the maximum volume level, an error tone sounds.
The error tone also sounds if you press the volume down key at the lowest volume.
