trying to increase my text alert tones

hi, im edman300, how is everybody doin? i got into the *#197328640# menu ( thanks to you guys), but how do i change the values? i thought i was more tech savvy than i obvioulsy am. lol

when i get the screen rcv codec gain WRITE
with a curser flashing, what do i do next?  itried typing in the box but hitting ok did nothing.

thanks, i can change them now, but only a single number. if i try to put in -21 i get 0
if i try to put in 12.50 i get 1. it is only reading one number. the -21 values are now 0
do i need to reset or anything to get the -21 and -20 values back? it wont let me enter more than one number and automatically goes back to the read screen. sry if im bein a pain.

this is what i was told to change them to, but i ended up with what is below

Existing Values----the settings before i tried changing them---
===========
1.txvol: 7 dB
2.dtmf_tx: -21 dB
3.cod_tx: 0 dB
4.cod_rx: 0 dB
5.cod_st: -20 dB
6.whisper_TxVol: 10 db

Updated Values------what i was trying to set them at-----
============
1.txvol: 12 dB
2.dtmf_tx: -21 dB
3.cod_tx: 5 dB
4.cod_rx: 0 dB
5.cod_st: -20 dB
6.whisper_TxVol: 5 dB

my current settings:----what i ended up with-----
==========
1.txvol: 9 dB
2.dtmf_tx: 0 dB
3.cod_tx:5 dB
4.cod_rx: 0 dB
5.cod_st: 0 dB
6.whisper_TxVol: 5 db

Yeah, when I tried to change bluetooth, it changed every value to the same... was very annoying. As to the values you want.... put in 1250 not 12.50- leave the decimal point out.

I think you are not doing it correctly. On the read screen you select the number of the item you wish to change. That takes you to the write screen. Do not use the number pad now. Instead tap in the text box and that brings up the qwerty or dial pad.  Use that to enter your values.

Easiest way to restore your values is here.
