TROUBLESHOOTING
All units must meet the basic requirements listed below for proper operation. Check these items first when troubleshooting a system problem:
• Adequate and stable primary power
• Secure connections (antennas, data and power)
• A clear transmission path between associated units
• An efficient, properly installed antenna system
• Proper configuration of unit settings
• Correct interface between the unit and other equipment
The unit’s LED indicator panel can provide useful information when troubleshooting. Refer to
3.1
Event Codes
When an alarm condition exists, the unit creates a message readable on a connected PC. Consult the Technical Manual for details.

COM PORT REFERENCE
) is commonly used to connect an external
DTE telemetry device to the unit, supporting either the RS-232 or
RS-485 (balanced) format, depending on how the device is configured. The unit supports data rates of 1200, 2400, 4800, 9600,
19200, 38400, 57600, and 115200 bps (asynchronous data only).
This connector mates with a standard RJ-45 plug available from many electronics parts distributors.

Hazardous Locations Notice
EXPLOSION
HAZARD!
When installed in hazardous locations, use only the serial and Ethernet connections on the unit’s front panel. Do
not use the USB port in hazardous locations.
RF Exposure Notice
To comply with RF exposure requirements, the antenna shall be installed to ensure a minimum separation distance of 20 cm from persons. The antenna may not be collocated or operated in conjunction with other transmitting devices.
Approved Antennas
Only approved antennas may be used on the unit's RF output connectors, as listed below. The use of non-approved antennas may result in a violation of FCC rules, and subject the user to FCC enforcement action.

Servicing Precautions
When servicing energized equipment, be sure to wear appropriate Personal Protective Equipment (PPE). During internal service, situations could arise where objects accidentally contact or short circuit components and the appropriate PPE would alleviate or decrease the severity of potential injury. When servicing radios, all workplace regulations and other applicable standards for live electrical work should be followed to ensure personal safety.
Manual Revision and Accuracy
This manual was prepared to cover a specific version of firmware code.
Accordingly, some screens and features may differ from the actual unit you are working with. While every reasonable effort has been made to ensure the accuracy of this publication, product improvements may also result in minor differences between the manual and the product shipped to you. If you have additional questions or need an exact specification for a product, please contact GE MDS using the information at the back of this guide. In addition, manual updates can be found on our web site at www.gemds.com.
Environmental Information
The manufacture of this equipment has required the extraction and use of natural resources. Improper disposal may contaminate the environment and present a health risk due to hazardous substances contained within.
To avoid dissemination of these substances into our environment, and to limit the demand on natural resources, we encourage you to use the appropriate recycling systems for disposal. These systems will reuse or recycle most of the materials found in this equipment in a sound way. Please contact GE MDS or your supplier for more information on the proper disposal of this equipment.
Product Test Data Sheets
Test Data Sheets showing the original factory test results for this unit are available upon request from the GE MDS Quality Leader. Contact the factory using the information at the back of this manual. Serial numbers must be provided for each product where a Test Data Sheet is required.
CSA/us Notice
This product is approved for use in Class 1, Division 2, Groups A, B, C & D
Hazardous Locations. Such locations are defined in Article 500 of the
National Fire Protection Association (NFPA) publication NFPA 70, otherwise known as the National Electrical Code. The transceiver has been recognized for use in these hazardous locations by the Canadian Standards
Association (CSA) which also issues the US mark of approval (CSA/US).
The CSA Certification is in accordance with CSA STD C22.2 No.
213-M1987.
CSA Conditions of Approval: The transceiver is not acceptable as a stand-alone unit for use in the hazardous locations described above. It must either be mounted within another piece of equipment which is certified for hazardous locations, or installed within guidelines, or conditions of approval, as set forth by the approving agencies. These conditions of approval are as follows: The transceiver must be mounted within a separate enclosure which is suitable for the intended application.The antenna feedline, DC power cable and interface cable must be routed through conduit in accordance with the National Electrical Code. Installation, operation and maintenance of the transceiver should be in accordance with the transceiver's installation manual, and the National Electrical Code. Tampering or replacement with non-factory components may adversely affect the safe use of the transceiver in hazardous locations, and may void the approval.
A power connector with screw-type retaining screws as supplied by GE
MDS must be used.
EXPLOSION
HAZARD!
Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous. Refer to
Articles 500 through 502 of the National
Electrical Code (NFPA 70) for further information on hazardous locations and approved Division 2 wiring methods.
Grounding Requirements
To minimize the chance of damage to the unit and connected equipment, a safety ground (NEC Class 2 compliant) is recommended which bonds the antenna system, chassis, power supply, and connected data equipment to a single-point ground, keeping all ground leads as short as possible.
Normally, the unit is adequately grounded if the supplied flat mounting brackets are used to mount it to a well-grounded metal surface. If the unit is not mounted to a grounded surface, it is recommended that a safety ground wire be attached to one of the mounting brackets or a screw on the enclosure.
The use of a lightning protector is recommended where the antenna cable enters the building; Bond the protector to the tower/support ground, if possible. All grounds and cabling must comply with applicable codes and regulations.
