ELT

Emergency Locator Transmitter

Maintenance


3/11/06

We replaced the batteries in our ELT unit for the 2nd time since we put it into service.

It was still working fine but when we took the unit apart for inspection of the battery voltage
we found that 3 of them were begining to leak acid which we all know isn't a good thing.

Specifications call for 6 Duracell MN1300 alkaline D batteries to be replaced before the date on the batteries themselves.

Ameri-King however strongly recommends
that the batteries be replaced on a yearly basis.


Another thing about the batteries

is that all of them must have the same expiration date on them.  For example in our case today we purchased 1 pack that had two batteries in it and another that had 4 batteries in it.  Donna actually had to look at each package to make sure that she bought ones that all expired on the same date.


Our ship also has an ELT remote unit that has a battery that
must be replaced every 8 years.

Specifications on it call for a Duracell DL1/3NB 3 volt lithium battery.


Testing this unit actually involves setting it off

and checking the two frequencies that it broadcasts out on to make sure the unit is actually sending out a signal.

Ameri-King says this unit should be tested every 3 months.

This can only be done during the first 5 minutes of each hour
and for no longer than 1.5 seconds at a time.
