PPP-12 Portable Power Pack with FishEasy 320C stowed for transport.
Turn the sonar unit on. If it doesn't work, make sure the battery termi-
nals are making good contact against the battery contacts. Also check
the wiring connections on the battery adapter. The red wire on the
power cable should be attached to the red wire on the battery adapter
and the power cable's black wire should be connected to the black wire
on the battery adapter.
If it still doesn't work, check the battery voltage. Most of the complaints
we receive about portable units result from stale batteries. Make sure
the ones you buy are fresh.
In cold weather the efficiency of dry cell batteries drops with the tem-
perature. We find it a good idea to have the sonar unit good and warm
along with the batteries before we leave home.
If the batteries do lose a charge, you can sometimes restore them by
placing them in a warm room or car interior. A better way is to replace
them with batteries that have been kept warm.
WARNING:
Never heat the batteries over an open flame or direct hot
air onto them. A fire or explosion could result.
