Level 1 and 2 Service Manual Product Overview
Product Overview
Motorola ROKR E2 mobile telephones feature global system for mobile
communications (GSM) air interface, general packet radio service (GPRS) transport
technology, and wireless application protocol (WAP) Internet browser. The mobile
telephone uses a simplified icon and graphical-based user interface (UI) for easier
operation, allows short message service (SMS) text messaging, and include clock,
alarm, datebook, calculator, and caller profiling personal management tools. The
E2 is a tri band phones that allows roaming within the GSM 900MHz, DCS 1800
MHz and PCS 1900 MHz bands, or the GSM 850MHz, DCS 1800MHz and PCS
1900MHz bands, depending on factory programming.
E2 telephones support GPRS, EDGE, SMS, EMS, and MMS in addition to
traditional circuit switched transport technologies. GPRS or EDGE, where
available, provides substantial increases in mobile data communications
performance and the efficient use of radio spectrum. A key advantage is the
provision of a permanent virtual connection to the network. This “always on”
connection is possible because GPRS and EDGE use packet data transfer so that,
for example, email can be downloaded in “background mode.” There is no need for
the user to re-connect before requesting a service, eliminating connection set-up
delays and adding convenience and immediacy to data services access. The “virtual”
nature of this connection means that network resources are not consumed during
periods when a user is not actually sending or receiving data.
The telephones are made of polycarbonate plastic. The display and speaker, as well
as the transceiver printed circuit board (PCB), microphone, charger and headphone
connectors, and buttons are contained within the candy bar form-factor housing.
The 880 mAh Lithium Ion (Li Ion) battery provides up to 240 minutes of talk time
with up to 216 hours of standby time

. The phone accepts 3V and 1.8V mini
subscriber identity module (SIM) cards which fit into the SIM holder under the rear
housing cover. These telephones feature a 240 x 320, 262k QVGA TFT color display
and an internal antenna.
Features
E2 telephones use advanced, self-contained, sealed, custom integrated circuits to
perform the complex functions required for GSM GPRS 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 the E2 include:
• 1.3 Mega Pixel Camera w/ flash
• Standard 3.5 mm headset jack
• Dedicated music keys
• FM Radio
• FOTA (Firmware Over The Air)
• iTunes or Native Media player
• SD memory card (plug and play)
• Stereo audio (via Stereo BT or wired headsets)
• Video capture, playback (15fps)
• Lower voltage technology that provides increased standby and talk times
• Extended GSM (EGSM) channels
1. All talk and standby times are approximate and depend on network configuration, signal strength, and features selected. Standby
times are quoted as a range from DRX=2 to DRX=9. Talk times are quoted as a range from DTX off to DTX on.
