Transceiver RH-21
Introduction
The RH-21 (Model 3520) transceiver is a single-band TDMA800 transceiver unit.
The transceiver consists of engine module (1cb) and assembly parts.
The transceiver has a full graphic display and the user interface is based on the Jack 3.2
UI with two soft keys.
An internal antenna is used, there is no connection to an external antenna.
The transceiver has a low leakage tolerant earpiece and an omnidirectional microphone,
providing excellent audio quality.

Operational Modes
There are several different operational modes. Modes have different states controlled by
the cellular SW. Some examples are: Idle State (on ACCH), Camping (on DCCH), Scanning,
Conversation, No Service Power Save (NSPS) previously OOR = Out of Range.
In the power off mode, only the circuits needed for power up are supplied.
In the idle mode, circuits are powered down and only the sleep clock is running.
In the active mode, all the circuits are supplied with power although some parts might
be in idle state part of the time.
The charge mode is effective in parallel with all previous modes. The charge mode itself
consists of two different states (i.e., the fast charge and the maintenance mode).
The local mode is used for alignment and testing.
