SECTION I
GENERAL INFORMATION
1.1 SCOPE OF MANUAL
This manual contains informationnecessaryto install, operate, and maintainthe RCU-931 0 Remote Control Unit.
Installation information is in Section II. Operating Instructionsare in Section Ill. Theory of Operation is in Section
IV. Maintenance and Repair Procedures are in Section
V. Information in this manual applies to all equipment
configurations, unless otherwise stated in the text or illustrations.
1.2 PURPOSE OF EQUIPMENT
The RCU-931o Remote Control Unit is designed to provide complete operational control of a remotely-located
RT-9000 Transceiver.
The RCU-9310 allows
an operator at a remote site to access and perform all transceiver primary functions:
selecting the transmission mode and power level; establishing operating frequencies; automatically tuning the
transmitter and associated antenna coupler; manual tuning; and loading, scanning, and operating with preset
frequency channels.
The RCU-9310 also enables the remote operatorto perform several non-operational, periodic, functions related
to equipment setup and maintenance. Diagnostictests--tothe lowest repairable unit (LRU) -- can be selectively
executed on both the transceiver and the remote control unit itself. Other functions include: selection of CW
keying speed and filtering options; connection ofexternal devicestothetransceiver'saudio inputand outputlines;
local I/O portconditioning; transceivermemorydump(i.e., clearing all preprogrammed channels); andtransceiver
metering at the remote control panel.
In addition, the RCU-931 o allows the remote operator to access and use the transceiver's advanced automated
functions: receiver scanning
of preprogrammed channels; programming and execution of Automatic Link
Establishment (ALE) operations; "sounding" (broadcasting to selected stations in a predefined network); and
"network call" (broadcasting to all stations in a network).
1.3 GENERAL DESCRIPTION
The RCU-931o is intended for useon table tops or in base station 19-inch rack installations. However, its rugged
package makes the RCU-9310 adaptable to various environments. Internally, the RCU-9310 is designed with
the service technician in mind. Built-in test equipment (BITE), with descriptive front-panel readouts, and .
modularized plug-in assemblies rnake the MTTR (Mean Time To Repair) less than fifteen (15) minutes. LEDs
located on the assemblies allow the technician to pinpoint faulty modules immediately. The RCU-931 0 is
lightweight for its capability, weighing only 20 pounds. Available in Olive Drab (OD) or Grey, the RCU-931 0 is
compatiblewith most radio station colorschemes. (If a particular colorotherthan ODor Greyisrequired, contact
the Sunair Marketing Department for information concerning changes
to the standard colors.)
The RCU-9310 has a simple, easily understood, front panel that duplicates the functions of the RT-9000
Transceiver. Firsttimeuserscanoperatetheequipmentwithoutextensivetraining. Thewide screen liquid crystal
display (LCD)
is continuously updated by the microprocessor with operational status such as Frequency,
Channel, Mode, BFO, AGC, Power, Local or Remote Control. The LCD also contains a bar graph meter which
selectivelyindicatessignal strength,forward RF power, reverse RFpowerand Remotetransmitand receiveaudio

ISUNAIR RCU-9310 I
The built-in-test routines include power amplifier and antenna coupler status in plain English messages which
appearin the display. Softkeys and a softkey menu LCD display selected options such as Time,
CW Filter, etc.
The softkeys also provide access to remote control configuration, meter selection, speaker control and other
operating features not found on the front panel keyboard.

equipment
or parts. Information regarding location and mounting considerations, power requirements, ground
system hookups, and cabling considerations is also provided.
2.2 UNPACKING AND INSPECTION
As soon as you have received your unit(s), unpack and inspect all components and accessories. Check the
packing list to be sure you have received all items ordered, and that all items necessary for operation have been
ordered. INOTE: I Be sure to retain the carton(s) and associated packing materials
should it
be necessary to reship the equipment.
Do not accept a shipment when there are visible signs
of damage to the cartons until a complete inspection is
made. Ifthere is a shortage ofitemsorany evidence
of damage, insist on a notation to that effect on the shipping
papersbeforesigning the receiptfrom the carrier. Ifconcealed damage

accepted, notify the carrier immediately in writing and await his inspection before making any disposition ofthe
shipment. A full reportofthedamageshould also be forwarded to Sunair'sProductServices Department. Please
be sure to include the following information for prompt service:
a) ORDER NUMBER.
b) MODEL AND SERIAL NUMBER.
c) NAME OF TRANSPORTATION AGENCY.

Upon receipt of this information, Sunair will make arrangements for repair or replacement.
2.3 RETURN OF EQUIPMENT TO FACTORY
The shipping carton for the RCU-931 0 has been designed to protect the equipment during shipment. The
container and its associated packing materials should
be used to reship the equipment.
When necessary to return equipment to Sunair for warranty or non-warranty repair,
an authorization number is
required. This numbercan be obtained from our Product Services Department: TELEPHONE: [phone],
FACSIMILE: [phone].
If the original shipping carton is not available, be sure to carefully pack each unit separately, using suitable
cushioning material where necessary. Very special attention should
be given to providing enough packing
material around connectors and other protrusionsfrom the unit. Rigid cardboard should be placed atthe corners
of the equipment to protect against denting. DO NOT USE DUNNAGE (e.g., STYROFOAM PEANUTS) FOR
PACKING PROTECTION; it may allow the unit
to shift while being shipped, and, therefore, become damaged.
