radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference
in which case the user will be required to correct the interference at his own expense.
1.3. Safety / Warning Information
Blasting Caps and Blasting Areas
To avoid possible interference with blasting operations, turn off this radio or remove
the DC power when you are near electrical blasting caps, in a blasting area, or in
areas posted: “Turn off two-way radio.” Obey all signs and instructions.
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive atmosphere.
Do not install this product for use in areas with potentially explosive atmospheres. Do
not remove, install, or charge batteries in such areas. Sparks in a potentially
explosive atmosphere can cause an explosion or fire resulting in bodily injury or even
death.
Safety
Warranty is void if the product is used in any way that is in contradiction with this
manual, or if the radio modem housing has been opened or tampered with.
1.4. OEM Use
This radio module is for OEM use, and it is the responsibility of the OEM user to notify

station sites. It is not intended for portable applications.
The RV-M6S-UC (UHF version) safety information:
The maximum permissible exposure to the antenna is:
The minimum separation distance is 30cm.
Max peak output power at antenna input terminal = 33.42 (dBm)
Max peak output power at antenna input terminal = 2197.85 (mW)
Antenna gain (typical) = 0 (dBi)
Maximum antenna gain = 1.0 (numeric)
This radio is restricted to occupational use, work related operations only where the
radio operator must have the knowledge to control the exposure conditions of its
passengers and bystanders by maintaining the minimum separation distance of
following range. Failure to observe these restrictions may result in exceeding the FCC
RF exposure limits.
Antenna Installation
For rear deck trunk installation, the antenna must be located at least the following
range away from rear seat passengers and bystanders in order to comply with the
FCC RF exposure requirements.

B. Connect a 50 ohm antenna to the module’s unique antenna connector.
C. To not touch the antenna when the radio is on and can transmit.
D. Use it on a channel frequency within the frequency band it is certified in.
E. You product using this must meet the specific requirements in this manual.
F. Input DC voltage that is low noise (<100mV noise) and within the DC input specification.
G. On our product and you user manual, specify the FCC instructions and all safety details.
H. Usage conditions are for mobile, and fixed-mount equipment configurations, as applicable.
I. Ensuring your compliance for RF exposure requirements.
J. An Integrator of this radio that uses it in a portable host device is required to get additional
SAR testing to be performed.
K. Integrators must provide a physical or e-label that states: “Contains FCC ID” with their
finished product. Use this Raveon radio’s FCC ID on the label.
L. This Data Radio modular transmitter is only FCC authorized for the specific rule parts in
the FCC grant. Raveon, this product manufacturer, is
M. The host product manufacturer that uses this product is responsible for compliance to any
other FCC rules that applies to the host, not covered by the modular transmitter grant of
certification.
N. The final host product that uses this product still requires Part 15 Subpart B compliance
testing with the modular transmitter installed.

2. Overview
The M6 RF radio modem module is capable of high-speed narrow-band data
communications and is compatible with Raveon’s M7 and M6 series Radio Modems.
Its powerful microprocessor enables it to perform as both a data radio modem and a
paging receiver. It contains a receiver, a transmitter, and modem, creating an easy-to-
use transparent data radio link. The M6’s user interface is asynchronous digital data
into and out of the M6.Modem operation is virtually transparent to the user and the
configuration of the modem is via the user serial port. The M6 module may be put in
Raveon’s Tech Series enclosures with a myriad of various I/O interface options.
The command-line interface is similar to Raveon’s other data radio products, and
configuring the mode is very easy. The M6 also has a digital input pin that may be
used to electrically change modem types between data modem and paging modes.
The M6 is an easy to use and its re-programmability makes it extremely versatile.
Most parameters within the modem may be re-configured to optimize it for specialized
operations, extended range, or higher data throughput.

2.2. Firmware Updating
The M6 is a software based radio and modem. There are times an existing unit needs
to get updated with a new feature, and this can often be done by loading the new
firmware into the older radio modem. In firmware program called the “Boot Loader” is
permanently installed inside the M6’s microcontroller. During power up, it checks to
see if the user wants to update the application program in the microcontroller. The
STAT2 pin is used to trigger the Boot Loader. See application note AN186 for details
on how to boat load new firmware into the M6.
