Is there a way to adjust the volume? because #1 seems a bit too loud and theres nothing in between that and 0

Replace the main board

On the D1680, D1481, and similar phones,
the three levels of ringer loudness plus
"off " are set at the base using the same
[ - ] Volume [ + ] buttons used to adjust
the answering machine message volume.

Pushing the [ + ] and [ - ] keys will
set the ringer to be louder or softer. A
number in the "message counter display"
will report the relative loudness...pushing
[ - ] below level-1 loudness will show
"0" loudness and an announcement of
"Ringer off" will be spoken. From here,
a single push of [ + ] will turn the ringer
on to level-1 and play a ~10 second
sample of the ringer at that volume:
while it is playing the sample ring,
subsequent pushes of [ + ] or [ - ]
will toggle the loudness levels of
( off, 1, 2, 3 ).

Good luck!

Hi there,

Typically the left or right knob should adjust the volume by turning it counter-clockwise. However, some companies need to make this a bit more advanced or difficult. If this is the case, you can try pressing the audio button on the device. If it provides you with any options on the screen, search for anything which indicates changing the volume control. (It may also be under Menu)
Once you do that you should be able to turn the sound down with either the knob on the left or the arrows on the right.

Memory Initialize operation

NOTE: The execution of this function returns the adjustment codes to the preset values, therefore, adjustment

data will be lost.

Procedure

(1) Enter Adjustment Mode.

(2) Select MEMORY INIT adjustment code (No.704) and change the data value from 0 to 1.

(3) Activate MEMORY INIT by pressing OK button for more than 3 seconds.

(4) Select No.374 and change data value from 1 to 0.
(5) Check that the receiving channel goes to AV1. Unit is set to preset values

1. Press the menu key
2. Press the left or right arrow to show VOLUME CONTROL, press OK
3. Press the left or right arrow to show CALLING TONE, press OK
4. Press the left or right arrow to select volume (0 - 3), press OK
5. Press the STOP/RESET key.

If you are using a cable box...turn down the sound on the cable box.

There are 2 channels, Which means there are 2 sets of knobs ... One for clean and one for crunch. Start out with a low master volume and set up the crunch, Then the clen and switch between the 2 and make adjustments until they match volume wise ... Then turn the master up.

it can never be too loud

if you know how to solder, try to solder the system ic an the sound ic but be careful of short circuit.

The volume is at maximum. There is nothing that can be done.
