 mobile telephones feature Code Division Multiple 

Access (CDMA) technology. The mobile telephone uses a simplified icon and 
Graphical user interface (GUI) for easier operation, allows Short Message Service 
(SMS) text messaging, and includes clock, alarm, datebook, calculator, and caller 
profiling personal management tools. The K1m telephones include a built in 
camera. The phone provides embedded ring tones including VibraCall vibrating 
alert and 32 Downloadable/Customizable iMelody ring tones. The K1m telephones 
are dual band that allow roaming within the CDMA 800 MHz and PCS 1900 MHz 
bands.

The K1m CDMA phones consist of a main housing assembly and a flip assembly. 
The main circuit board, battery, EMU connector are located in the main housing 
assembly. The camera on the K1m phones is located in the hinged flip assembly.

The flip assembly contains the entire hinge mechanism. It is attached to the main 
housing by four screws. The main display is on the inside of the flip assembly and 
a one line LED display on the outside of the flip assembly. The main display on the 
K1m phones is a 176 x 220 pixel 65k TFT LCD. The external CLI display is a 96 x 
80 pixel 65K CSTN LCD. The camera module is a 1.3 mega-pixel CMOS camera.

The main housing assembly includes a battery cover, chassis, main circuit board, 
keypad plastic front housing, and internal antenna.

The main circuit board contains the Receiver, Transmitter, Synthesizer and Control 
Logic Circuitry which together comprise the dual band tri-mode phone electronics.

The telephones are made of polycarbonate plastic. The display and speaker, as well 
as the 18-key keypad, transceiver printed-circuit board (PCB), microphone, charger 
and headphone connectors, and power button are contained within the flip form-
factor housing. The 880 mAh Lithium Ion (Li Ion) battery provides up to 254 
minutes of talk time in CDMA mode with up to 435 hours of standby time

1

. An 

optional extended capacity 1700mAh Li Ion battery is also available.

 telephones use advanced, self-contained, sealed, custom 

integrated circuits to perform the complex functions required for CDMA 
communication. Aside from the space and weight advantage, microcircuits enhance 
basic reliability, simplify maintenance, and provide a wide variety of operational 
functions.

Features available in this family of telephones include:
• Ultra Slim form factor 
• Video Capture & Playback MPEG4 (15 fps QCIF)
• Audio/Video streaming (3GPP)
• Video Progressive Download
• Dedicated Carrier Key 
• Integrated Bluetooth Connectivity (Class 2)
• 1.3MP digital camera with 8x digital zoom
• Micro SD slot for upgradeable memory
• Dynamic Idle
• 17-30MB of embedded end user memory

1. All talk and standby times are approximate and depend on network configuration, signal strength, and features selected.
