The phone has a 4-way directional ‘Navi’ key which includes a centre select/menu button. 2 soft keys are either side of this.
To insert the required symbol (e.g. : / . @) into your settings, simply press the number ‘1’ key until the symbol appears.
Press the Menu button (Navi key).
Highlight ‘Browser’ and ‘Select’ (left soft key).
Highlight ‘Profile settings’ and ‘Select’ (left soft key).
Highlight a clear profile and press ‘Select’ (left soft key).
Highlight ‘Profile name’ and lycamobile.
When you have typed the information in, do not press ‘OK’ (Navi key) unless otherwise told to, as this will save the profile and send you back to the profile select screen. If at any stage you to this by mistake, then just select the profile again.
