BATTERIES & MAINTENANCE
The MT410G PLB is fitted with the very latest in
high capacity battery technology. These batteries
are able to operate within a temperature range of
-20°C to +55°C.
The full operational capability of your beacon
may not be available if the batteries fitted have
exceeded their replacement date, as shown on
the body of the unit. Prior to reaching this date,
make arrangements to have your MT410G
returned for service.
NOTE:
PLB maintenance operations, including beacon
refurbishment, require that the beacon be returned to
a manufacturer approved service facility.
A list of authorised Service Centres can be found at:
www.gme.net.au.
The beacon refurbishment due to expiry or usage is not
covered by the product‘s Warranty.
NOTE:
MT410G batteries are not user replaceable.
Although the MT410G is otherwise maintenance
free, routinely following these few simple
steps will help ensure that your beacon will be
operationally ready if called upon:
1. Test the PLB at the recommended interval.
2. Confirm the SAFETY SEAL has not been broken.
3. Check that the batteries have not passed their
replacement date.
4. Inspect the MT410G for physical damage
or deterioration.
5. Keep the unit clean by wiping over with a damp
cloth (warm water and mild detergent are
suitable), then dry.
If there is any doubt as to the products’
serviceability, immediately contact your authorised
Dealer or Service Centre for advice.
TESTING THE PLB
It is recommended that you test the MT410G at
regular intervals to ensure it is fully functional.
You should also test the beacon prior to an
extended journey.
WARNING: DO NOT
over test – testing consumes
some battery power, no more than once per month.
DO NOT
deploy the antenna as this will break the seal
and activate the beacon to transmit a distress signal
after 60 seconds.
You may test the PLB using the following
procedure:
1. Remove the beacon from the carry pouch.
2. Use the key (attached to the lanyard) to slide
the self test switch down and then release, a
double beep and flash of the light will indicate
the MT410G is functioning correctly.
GPS SATELLITE ACQUISITION TEST
The standard self test procedure is more than
sufficient to perform a comprehensive check of
your beacon without consuming too much battery
capacity. On occasions, and no more regularly
than on average once a year, you may wish to
perform a GPS satellite acquisition check.
WARNING:
The MT410G will limit the number of
GPS satellite acquisition checks to a total of 8 over the
lifetime of the battery pack. After this limit is exceeded
you will no longer be able to perform this test until
a beacon refurbishment has been undertaken. If you
attempt a GPS acquisition check, the MT410G will
produce a low frequency audio tone and will not
proceed with the test.
Whereas the routine self test verifies the GPS
receiver’s circuitry, the full test will include the
operation of the special GPS antenna as well.
1. This test consumes much more power than a
standard self test so choose a test location with
good visibility of the open sky above. A quick
satellite acquisition means a short test, and less
wasted power consumption.
2. Carry out a self test in the usual way but rather
than releasing the key, continue to hold it in
position.
After the self test pass confirmation,
both the light flash and the internal beeper will
start. Count a further four flashes/beeps then
immediately release the key.
