Motorola Fone

The F3 was the first mobile phone to use electronic paper in its screen. Motorola used the term ClearVision to describe the new display, which was manufactured using E Ink's electrophoretic imaging film.[1] The electronic paper main display allowed for the phone's thinness (no glass), longer battery life, and outdoor viewability (paper-like reflectivity). It had a backlight for the keypad and a slit that projects the backlight onto the screen so the display can be seen in darkness.

The characteristics of the display were fairly restrictive. The text display contained only two lines of six characters each, making the use of text messaging (SMS) and data services less practical than on standard LCD displays. The display used a fixed 'digital clock' style font, with no functionality for changing between upper case and lower case text. All SMSs sent by the F3 were received entirely in lower case, and each character of any SMS received by the F3 is displayed in whichever case made the most sense using the font. Also, the non-alphabetic characters were severely limited due to this display, as the phone could only provide support for the following characters:

• Comma (,) (periods . in incoming text messages are displayed as commas)
• Hyphen (-)
• Question mark (?)
• At-sign (@)
• Asterisk (*)
• (+), to write this character, hold down the 0 key

No other non-alphanumeric characters could be entered, and on receiving an SMS any non-alphabetic character not listed above was displayed as a hyphen.

Although the display could be restrictive when it came to text applications, the display was very energy efficient and conducive to extremely long battery life.

Since the F3 had only two lines of fixed icons on the top and bottom of the display, as well as one line of six 14-segment characters and another line of six 7-segment numbers available on its display, the user interface was very different from the usual menu structure normally found on mobile phones. The only thing resembling a (flat) menu was accessed by pressing left/right on the central button: It allowed writing an SMS, reading a saved SMS, call history, choosing the ringtone (out of seven melodies), setting date and time, and setting the alarm clock. The menu was visualized by fixed icons in the bottom row, following the left/right pattern of the navigation button.

The F3 had a few dedicated buttons for opening the address book (top right), canceling any action (the red button), dialing the currently displayed number (the green button) and an "action" button (top left). A few more functions were available by shortcuts: When making a call, pressing the action button twice switched the loudspeaker on/off, while pressing up/down controls the speaker volume. The same button used in standby toggled voice prompts, while pressing up/down controls ringtone volume. When the phone rung, due to incoming calls, the ringer could also be silenced by pressing up/down. All activated features (set alarm clock, activated vibration mode, roaming, ...) were indicated by simple icons in fixed positions in the top row, and every successful action acknowledged by an "OK" icon flashing on and off a few times. The only context-sensitive button was the action button which was used for "OK" on options as well as choosing a number or address book entry when writing an SMS or for answering a received SMS.

Reception strength (left) and battery status (right) were constantly displayed in two prominent strips above the actual display. Both were readable in any light condition and from considerable distances.

The F3 Motofone was designed for usage in developing countries and sported a display which coped well with both bright sunlight and very dim light. Voice prompts also explained the current function in a choice of languages, depending on region; a unit bought in Germany offered German, English and Italian. It was also fairly solid and rugged and could survive not only rough handling but also very dusty and/or damp conditions well, as the case had only two openings (a charger/headset jack and the battery cover) as well as a totally sealed keyboard. There are even videos on the Internet showing the F3 being thrown from a 3-story building into tarmac, and being run over by a car on a gravel surface.[2] The phone survived intact.

The charger/headset jack for the F3 Motofone (and variants) was not a standard 2.5 mm or 3.5 mm headset port. It was a DC connector that can support mono sound quality. This is not well documented at Motorola, and internal documentation indicates the jack is a standard 2.5 mm TRS connector jack. The jack shown on the Motorola site clearly has a pin in the center of the jack, prohibiting use of a standard 2.5 mm plug. A mono headset was available as part number CFLN6103AA and the name of it is Motorola S215 Pedestrian Kit. This is a headset only and not an adapter.

The F3 had two internal antennas to maximize reception even when partially shielded by a hand or other obstacles, and a loud maximum volume for ringtones and loudspeaker to facilitate usage in crowded city environments or public transport. The unique default ringing mode vibrates silently for several seconds, then rings at modest volume, then with full volume. A vibrate-only mode and modes with fixed volume can also be set. To ease repairs or recycling, it can be opened by four Torx screws on the back.

The F3c was available in Q4 2006, and was the CDMA version of the F3.[3]
