This feature allows you to connect an Original Equipment Manufacturer (OEM) or third-part Control
Head to the transceiver Rear Accessory Connector (RAC). The display of the OEM Control Head has
the same functionality and look as a Motorola Solutions Control Head.
The OEM Control Head can be used in one of the following modes:
Single Control Head mode
The OEM Control Head is the only control head connected to the transceiver.
Dual Control Head mode
The OEM Control Head is connected to the transceiver together with either a Remote Ethernet
Control Head (RECH) or a Telephone Style Control Head (TSCH).

One-Touch Dial
This feature allows you to call by pressing and holding one of the keys (1-9).
NOTE: If the One-Touch Button feature is disabled, One-Touch Dial is disabled as a
consequence. If no feature is assigned to a button that you press, your radio displays an
Unassigned Button message.
In RMS mode, the One-Touch Button feature is disabled.

Radio Messaging System (RMS)
NOTE: This is a Software Selling Feature.
The Radio Messaging System (RMS) feature allows the radio to receive and send RMS messages
through the TETRA network using the Short Data Service (SDS-TL) or Status (STS) as the transport
layer.
NOTE: One-Touch Buttons are disabled in the RMS mode.
There are two types of RMS messages:
•
RMS Status – a predefined code that is sent bidirectionally between the radio and the service
provider. The radio can have up to one hundred statuses that are assigned to numeric keys from 0
to 9. A received RMS status is displayed on the home screen.
•
RMS Free Text – (available in SDS-TL only) a unidirectional message containing free text
that is sent to the radio by the service provider. Since this type of message may be longer,
the radio displays only its beginning on the home screen. To view the full message, go to
Menu→Messages→RMS Box.
The latest RMS free text or the latest received or sent RMS status is kept on the home screen until the
next power cycle.
RMS free text messages and incoming and outgoing RMS statuses are stored in the RMS Box. Its
capacity is maximum one hundred entries for incoming and outgoing RMS messages. If the RMS Box
is full, any new incoming or outgoing RMS message overwrites the oldest message (received or sent).
The latest RMS free text is kept on the home screen until the next power cycle. The latest received or
sent RMS status is kept on the home screen until the next power cycle or up to 30 seconds (depending
on the settings configured by your service provider).
The radio receives and sends RMS messages only from and to the numbers predefined by your
service provider.
See Sending an RMS Status on page 79 on how to send an RMS message.
