instrument will reply to range interrogations. If the PORT-LF is being shipped or stored it should
be disabled to conserve battery life.
The PORT-LF should also be left disabled while deployed to conserve battery life. If the system is left
enabled and it pings 512 times, it will disable itself to save battery life. Simply send the ENABLE command
to use it again.
4.4 Post Deployment
After recovery, the Unit should be cleaned and rinsed with fresh water to avoid salt buildup and
deterioration of mechanical parts.
A visual inspection of the Housing and release mechanism should be performed to detect any signs of
damage, excessive wear, corrosion, etc.
If the PORT-LF is not to be used again soon, the Unit should be turned off (follow procedure described in
sub-section
0 ).
If the Unit is to be stored for a long period of time, the batteries should be removed. See Maintenance
