Caution
: If the O-ring is damaged and requires
replacement, do not remove it using a sharp metal
instrument; doing so will scratch the O-ring seating
surface. Instead, use a softer instrument, such as a
wooden toothpick.
If you remove an O-ring, inspect the seating surface on which it rests
for foreign material, and clean if necessary. Note that for each O-ring,
there are two seating surfaces, which are joined by the O-ring
connection. Before inserting a new O-ring, apply a suitable grease to
it, such as
Dow Corning® 4 Electrical Insulating Compound
.
When ordering O-rings, specify Part Number ORG-06.
Cables
All cables should be kept free of cuts. If damaged, the assembly or
cable should be replaced. Use of plastic strapping (“Quick-Tie”, Zap-
Strap”) can damage cables and cause leakage/corrosion and failure.
Use of these ties voids warranty.
Regular Maintenance of the Battery
Every 3 to 6 months it is important to fully discharge and then fully
recharge the battery in the belt pack.
This is done by removing the
transducer, then turning ON the belt pack for 36 hours.
The
transducer is removed so that the belt pack will turn on and remain in
receive mode if the pack is already close to full discharge.
If this procedure is not followed then according to the battery
manufacturer, it is possible that the battery can develop a shorter
operating time as it will be undergoing partial charge/discharge
conditioning.
It is also important to be aware that Nickel type batteries lose charge
over time. This is a phenomenon called “self discharge”. After a full
charge, after one day the pack will lose 10% charge, and every
month thereafter an additional 10% to 15% charge.
