It is mandatory that radio installation in vehicles fueled by
liquefied petroleum gas conform to the following standard:
National Fire Protection Association standard NFPA 58 applies to radio
installations in vehicles fueled by liquefied petroleum (LP) gas with LP
gas container in the trunk or other sealed-off space within the interior of
the vehicles. The standard requires that:
1.  Any space containing radio equipment shall be isolated by a seal
from the space in which the LP-gas container and its fittings are
located.
2.  Remote (outside) fitting connections shall be used.
3.  The container space shall be vented to the outside.
Vehicles With an Air Bag
An air bag inflates with great force.  Do not place objects,
including portable or mobile two-way radios, in the area over
the air bag or in the air bag deployment area. If improperly
installed or placed wireless equipment is  in the air bag
deployment area and the air bag inflates, serious injury could
result.
Installation of the MICOM-2E radio should be performed by a
professional installer/technician qualified in the requirements for such
installations. An air bag’s size, shape and deployment area can vary by
vehicle make, model and front compartment configuration (e.g., bench
seat vs. bucket seat).
Contact the vehicle manufacturer’s corporate headquarters, if
necessary, for specific air bag information for the vehicle make, model
and front compartment configuration involved in your communication
equipment installation.

Restrictions
Because this radio contains a transmitter, federal law prohibits
unauthorized, non-licensed personnel from adjusting or maintaining it. If
any operational difficulties should arise while using this product, report
them to authorized service personnel as soon as possible.
Do not attempt any unauthorized modification to the radio.

Transmitter Features
The maximum output power of the transmitter is 125 W PEP (Peak
Envelope Power), with an average transmission duty cycle of 1 to 4,
thus enabling even the CW (Continues Wave) signal to be transmitted at
the maximum available power.  Output power can be preprogrammed to
one of the four possible levels: 25W, 62.5W, 100W and 125W.  Accurate
sensors are used to keep the output power within the nominal value.
The transmitter includes thermal protections.  If, for any reason, the
transmitter internal temperature exceeds the maximum permitted
temperature, the output power is automatically reduced to avoid any
fault due to excessive heat.
Mismatch protection is also included.  If the VSWR (Voltage Standing
Wave Ratio) rises to more than 2:1, the transmitter will be inhibited in
order to avoid any damage and a message will be displayed.

Receiver Features
The radio utilizes Digital Signal Processing for implementing most of the
reception functions like demodulations, narrow filtering, automatic gain
control, noise blanking, and squelch.
The automatic digital noise blanker is activated whenever repetitive
noise (e.g. ignition spikes) is encountered in the received signal.  The
digital syllabic (speech identifier) squelch is activated whenever speech
is identified, thus opening the audio path.  However, if speech is not
received, the audio path is muted, thus preventing background noise
from disturbing the operator.
Frequency Sources
Two types of frequency sources are available for the MICOM-2E radio.
The standard 0.6 PPM DTCXO frequency source which assures a
frequency stability of better than ±18 Hz.  For frequencies lower than
10 MHz, it assures a frequency stability of better than ±6 Hz.
When higher frequency stability is required, the G478 0.1 PPM OCXO
frequency source can be ordered. It will assure a frequency stability of
better than ±3 Hz at 30 MHz.
Power Source
The radio is designed for 13.8 V ± 20% negative-ground operation and
may be connected to a standard 12 V battery.
CW Keying Operation
When the CW key is pressed, the radio transmits a continuous wave (at
the full programmed power) and stops transmission when the key is
released.
CW keying operation is enabled by connecting the Morse key, between
CW (pin #10) and ground (pin #18) at the accessory connector. If you
wish to operate CW keying with external headphones, the S809
Interface can be used, thus enabling a standard PL55 headphone and
standard PL99 Morse key to be connected to the accessories
connector.

Programmable Features
The radio can be programmed using an IBM-PC and the Radio Service
Software (RSS). Using this software, the radio can be preprogrammed
for the following features:
· Up to 200 simplex/half duplex channels at SSB (J3E), AME (H3E),
or Pilot (R3E) modes of transmission.
· Up to four levels of output power (up to 125W PEP and average).
· Five scanning groups of up to 200 channels, each with guard
channel.
