GME has combined over 20 years experience in designing and manufacturing EPIRB's to produce a product that leads the industry in personal safety equipment. The MT310 EPIRB complies with Australian and New Zealand standards for marine application (4330:1995) as well as meeting CASA regulations for aviation use.

Unique to the MT310 is a combined beeper/flasher alarm, which indicates the unit is fully useable in both the test and operate modes.

In addition it gives audible and visual warnings should the EPIRB be accidentally activated thus avoiding expensive and time consuming searches resulting from false alarms.

The MT250C is a totally waterproof self-righting satellite compatible EPIRB that has literally saved the lives of hundreds of mariners around the world. It is fully approved for registered vessels under provision of Marine Orders Part 25.

Supplied complete with a mounting bracket, the MT250C is easily installed on a bulkhead ensuring ready access in an emergency. If you are going offshore, your safety equipment is not complete without the MT250C. You owe it to yourself, your crew and your family.

An activated emergency beacon is located using an effect known as Doppler Shift. Due to the relative motion between the satellite and the beacon, the beacon's transmitter appears to shift in frequency. The signal variations are retransmitted to an LUT and then to a Rescue Coordination Centre (RCC), where the computers automatically analyse the Doppler shifts. The beacon's position can then be calculated by relating it to the satellite's precisely known position in orbit.

FEATURES
The GME EPIRB is a completely self-contained radio transmitter for emernencv use. When activated, it simultaneously transmits an internationally recognised distress signal on 1 21.5 and 243 MHz. The signal can be detected at distances of up to 400Okms by LUT base stations, (Local User Terminals), monitoring COSPAS/SARSAT satellites. The COSPAS/SARSAT system supplements the older system, whereby overflying aircraft report any EPIRB signals they hear, listening on the Aviation International Distress frequency 121.5 MHz, or the Military Distress Frequency 243 MHz.

TEST FACILITY
Both GME EPIBBs can easily be tested without the danger of accidentally transmitting a distress signal. For peace of mind it is recommended testing should be carried out on a regular basis. Simply follow the procedure as indicated in the instruction manual.

LONG LIFE BATTERIES
The GME MT310 EPIRB is fitted with long life Lithium Iron Disulphide batteries, while the MT250C features a Poly-carbonmonofluoride Lithium battery. These batteries have the great advantage of retaining up to 90% of their original AMP hour capacity after 10 years of shelf life. SMA regulations require that EPIRBs are serviced and batteries replaced when half the shelf life has expired. Consequently all GME EPIRBs are date stamped with a battery replacement date, 5 years from date of manufacture.

SAFETY SEAL
The GME MT310 EPIRB features a dual action process with a special seal placed across the power switch. To activate the beacon, the operator needs to push down the yellow switch, then slide it across the top of the EPIRB and in doing so, breaking the safety seal. The GME MT250C EPIRB comes with an orange warning tape across the recessed antenna. This tape is designed to tear if the antenna is raised or the EPIRB is switched on. NEVER raise the antenna or remove this tape except in an emergency.
