Battery Pack Replacement

Two battery pack configurations containing cells of different chemistries are used 

within this range of EPIRB;  they are not interchangeable between model types.

( eg: ‘MT403’)

Verify the model type shown on the original 
chassis. 
Only the first five (5) characters are significant 
for the purposes of determining which service kit 
type is to be used;

(i.e. MT400, MT401, MT403 or MT403G)

WARNING:  Is imperative that the correct battery service kit be used.
MT400SVC  is  for use only with ‘MT400’
MT401SVC is for use only with ‘MT401’ and ‘MT401FF’
MT403SVC is for use only with ‘MT403’ and MT403FF
MT403GSVC is for use only with ‘MT403G’ and ‘MT403FG’
