Transceiver RH-41 (Nokia 2260)
Introduction
The RH-41 is a dual band transceiver unit designed for TDMA800/1900 networks. The
transceiver consists of the engine module (ST6_11) and the various assembly parts.
The transceiver has a full graphic display and the user interface is based on a Jack style
UI with two soft keys. An internal antenna is used in the phone, and there is no connec-
tion to an external antenna. The transceiver also has a low leakage tolerant earpiece and
an omnidirectional microphone that provides excellent audio quality.

Operational Modes
Below is a list of the phone’s different operational modes:
1 Power Off mode
2 Normal Mode (Power controlled by cellular SW, includes various Active and Idle
states):
• Analog Modes (800 MHz only):
•Analog Control Channel, ACCH
•Analog Voice Channel, AVCH
• Digital Modes (800 and 1900 MHz):
•Control Channel, DCCH
•Digital Voice Channel, DTCH (Digital Traffic Channel)
•Digital Data Channel, DDCH
Both the analog and digital modes have different states controlled by the Cellular SW.
Some examples are Idle State (on ACCH), Camping (on DCCH), Scanning, Conversation,
NSPS (No Service Power Save, previously OOR = Out of Range).
3 Local mode (both Cellular SW and UI SW non active)
4 Test mode (Cellular SW active but UI SW non active)
