Siemens S40
Encyclopedia
Originally developed as the Bosch 1886 in 2000, the phone was branded as the Siemens S40 after Siemens acquired the Bosch
mobile phone division. The Siemens
S40 is a tri-band mobile phone that operates on the GSM-900, GSM-1800, and GSM-1900 networks. Communication with a computer can be done either through the infrared port (IrDA
) on the phone or a USB or serial port data cable. Its more distinctive features include the voice memo recorder, the mute feature for conversations, the ability to record phone conversations, and the ringtone composer (a useful alternative for those unsatisfied with the 47 monophonic
ringtones). Another notable fact about this phone is its very low SAR (specific absorption rate
) of 0.33, making it #10 on the CNET
's list of ten lowest-radiation cell phones as of 2005. Also it was one of the first phone with HSCSD.
The phone also supports WAP
1.1, SMS
, HSCSD, and T9
predictive text input.
The S40 includes a 104x64 pixel monochrome liquid-crystal display
with a blue backlight, an internal antenna, and rubbery buttons to prevent accidental dialing.
