Audible Keypad Tone is a facility that can be set on some handsets, which causes them to play a tone when the keys are pressed, so confirming that they have operated correctly. This was introduced to reduce airtime charges to incorrect numbers, although it also provides a better interface and positive feedback for the user. The sound played is usually the DTMF tone relevant to that particular number, and for consistency, another non-DTMF tone can be played when control keys are pressed

Automatic answer is a phone feature that allows a recipient to answer a call without the need to press any keys. Once the phone has started to ring the conversation can be started immediately, because the sound of the recipient's voice speaking into the phone's microphone will trigger the answering of the call

Automatic backlighting means that touching any key will illuminate the display and keypad for ease of viewing. The backlight will turn itself off automatically after a preset period, so avoiding excessive drain on the battery. This feature will only be available on mobile phones that have a backlight

Automatic redial is a feature designed to make it easier to dial numbers that are engaged. After the dialled number is found to be engaged, the phone will either repeatedly redial the number automatically, or it can be set to redial by pressing the appropriate key. This feature saves the user from dialling the number many times until a ringing tone can be obtained. Automatic redial will usually operate for a set number of redials before giving up, to avoid the negative consequences of battery drain, blocking the phone, and causing unnecessary network traffic
