How do i adjust the speeker volume?

Hit volume down then use on screen slider to move it up it will appear at top of screen to the right is volume up.

Dial *41 then the extension number *4001 may also work

read your instr. manual in how to use the extension rings for intercom
or get assistance support from Panasonic via ONLINE chat or phone

God bless you

The rubber volume button on the outside of the phone adjusts both the ringer volume and the call volume, which is how loud a caller sounds when on a call. If you are not on a call, the volume button will adjust the ringer volume. To adjust the volume of a caller, you must adjust the volume while on that call.

To do this, while looking at the inside screen, adjust the volume by using the rubber volume button, which can be found on the outside of the phone. Press the top of the button to increase the volume and the bottom of the button to decrease the volume. The inside screen will display the call volume level. You may also set the call on Speakerphone mode. If you have the Jitterbug J model, there should be a button labelled "SPKR" on the upper left corner of the keypad.

Sounds to me like the amp needs power. Is it usb powered? or have a wall plug?

some surround sounds do not put out loud sounds except from the front speakers only. Try using different inputs to see if it makes a difference.

Hi, Sorry you are having problems,
If I understand you correctly, you have your headphones plugged into the MacBook and are expecting sound to come out of your speekers ?
Well, if that is the case, you must know that the mac will automatically cut the signal to the speekers as soon as headphones are connected.
Now if you are saying that you connected the headphones to test it and found that whe you changed the volume, you could hear the change on the headphones, but when you unplug your head phones, you do not notice any sound difference on the speakers.
SO let's say that is the problem. First thing to always do, of course, is a full shut down and a clean start up with no headphones installed. Once you have booted up, try it again....
If it still does not work, go into your sound preferece pane in the system preferences and change some of the settings, like muting the sound and clicking the button that allows for showing volume in menu bar, unclick options go into the tabs go clicking and unclicking things... then quit and then go back into the sound preferences and set it the way you want, sometimes shaking it up a bit gets it back on track...
Good luck.

hello

okay i think your base is too full.

turn off the base of your speekers and then try to play a song or a sound...

if not go to control panel and then sounds and lower down the base volume bar
