Stuck on whisper mode

could be that the remote operation or cycle operation needs reprogramming as it indicates that the program has a corruption in it and the action is lost by that corruption
follow the user manual and do the reprogram sequence

Check the Pitch slide switch on the L. side of thr keyboard it should be in 10, 12 or 15 not in PS.

From Page 39 of the manual:


Selecting Options (right softkey) during a call displays a list of
features you may use during the course of a call. To select an
option, press the corresponding keypad number or highlight
the option and press . The following options are available

This mode is useful in meetings or public places.

keep ur finger on the (#) button that might work

The problem might be the hearing volume. As far as I know, the only way to change it is in the middle of a call.

Here's what you should try...

1) Call someone.
2) Using the silver button on the left side of the phone, press the up arrow key a few times until the volume is all the way up. It will say "Hearing Volume".
3) During the call, go into the options menu and select the first option that will say "Whisper Mode On/Off". Select that and your problem should be fixed.

I have a feeling he turned on high contrast mode (supposedly it's meant to make reading the screen easier for people who are disabled, I think it just hurts everyone's eyes). To change that, right click on your desktop and go to appearance and click on the top pulldown menu and select windows xp style. Hopefully that will fix it.

press "power on" and "home" keys (same time), then in menu: fligh mode off... and ready

It can only be repaired by the repair shop I think your son broke a lug on the inside it may need a new tray?
