Hi guy,
I bought a new Sony E454 DAP about 2 month ago. Yesterday, i search on net and somebody told me the method to run test mode (MPTAPP Menu) on it for changing the volume limited:
1. Turn power on.
2. Switch HOLD to ON.
3. Press those keys:
[>] - [<] - [Vol+] - [Vol-] - [>] - [<] - [OPTION] - [BACK] - [OPTION] - [BACK]
I tried this, change some settings and when i restart, the sound seem loud more, but when i press to select the FM radio, it's crash, then auto reset. After booting up, i try the "Reset all factory settings" on the "Common" menu and the FM Radio can work. But the range is now changed to Japan range (76-90MHz) (when i bought, it's 87-108MHz).
Can somebody help me to change it to the default?
