Battery Function

Battery Charge Indicator

The telephone displays a battery charge indicator icon in the idle screen to indicate the battery charge level. The gauge shows four levels: 100%, 66%, 33%, and Low Battery.

Battery Removal

Removing the battery causes the device to shut down immediately and lose any pending work (partially entered phone book entries or outgoing messages, for example). If battery is removed before the unit is fully powered down, the display will not display properly until the unit is powered down correctly and then repowered up. (Snowy screen).

All batteries can cause property damage and/or bodily injury such as burns if a

Econductive material, such as jewelry, keys, or beaded chains touch exposed termi- nals. The conductive material may complete an electrical circuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when placing it inside a pocket, purse, or other container with metal objects.

G

If the battery is removed while receiving a message, the message is lost.

To ensure proper memory retention, turn the phone OFF before removing the battery. Immediately replace the old battery with a fresh battery.

CDMA 800/1900 MHz specifications

Motorola has long been recognized as a key player in the telecommunications industry, especially with its contributions to mobile communications technology. Among its impressive portfolio, the Motorola CDMA 800/1900 MHz stands out as a significant offering, particularly in the realm of Code Division Multiple Access (CDMA) technologies. This article delves into the main features, technologies, and characteristics of this versatile mobile communication standard.

The CDMA 800/1900 MHz spectrum refers to the frequency bands used for CDMA network deployment, specifically at 800 MHz and 1900 MHz. These frequencies allow carriers to provide robust mobile coverage, enhanced network capacity, and better call quality. The dual-band capability offers a versatile solution for both urban and rural environments, as 800 MHz is known for its ability to penetrate buildings and cover larger areas, while 1900 MHz is effective in densely populated regions.

One of the standout features of Motorola's CDMA technology is its ability to accommodate multiple users on the same frequency channel. This is achieved through code-based separation, where unique codes are assigned to each user. This allows many calls to occur simultaneously without interference, enhancing network efficiency and user experience. Additionally, CDMA technology provides significant improvements in voice quality and clarity, thanks to its advanced error correction algorithms.

Another notable aspect of the Motorola CDMA 800/1900 MHz is its support for various technologies that enhance functionality. The integration of features such as 1xRTT, EV-DO, and later evolutions introduced functionalities like packet data services and faster download speeds. EV-DO (Evolution Data Optimized) significantly boosts data transmission rates, making it ideal for mobile broadband services and applications, such as video streaming and online gaming.

Security is a critical concern in telecommunications, and Motorola's CDMA technology offers robust security measures. The encryption algorithms used in CDMA help protect user data and maintain privacy during voice calls and messaging, ensuring a secure communication environment.

In summary, Motorola CDMA 800/1900 MHz epitomizes reliable and efficient mobile communication. Its dual-band functionality provides expansive coverage and enhances user experience through simultaneous voice and data services. Advanced technologies such as EV-DO and robust security measures further contribute to its appeal. As the telecommunications landscape continues to evolve, the legacy of Motorola's CDMA technology remains a significant part of mobile communication history.
