Navman FISH 4500/4600 - Manual (Page 28)

Removing the display unit
The display unit can be removed after each
use for protection against the environment or
security reasons.
When removing the display unit, ensure that
The FISH 4500/4600 has three sockets located
on the rear of the display unit. These are for
the:
• Power/data cable (black locking collar)
• Optional fuel transducer cable (white lock-
ing collar)
• Transducer cable (blue locking collar).
The collars must be locked for a watertight
connection.
The power cable has a black 8 pin connector
plug. Push this plug into the upper socket, which
has a black nut, then turn the collar to lock.
The optional fuel transducer cable has a white
8 pin connector plug. Push this plug into the mid-
dle socket, which has a white nut, then turn the
collar to lock. (If the fuel transducer cable is not
being installed, leave the dust plug in place.)
The sonar transducer cable has a blue 6 pin
connector plug. Push this plug into the lower
socket, which has a blue nut, then turn the col-
lar to lock. Do not cut the cable. If necessary,
extend the cable by adding a Navman 13 ft. (4
m) extension cable (a maximum of one cable
can be used).
If possible, route the transducer cable away from
other wiring on the boat. Electrical noise from
engine wiring, bilge pumps and other electri-
cal equipment can affect the display unit. The
shortest and most direct connection to the boat’s
battery helps to minimise voltage drop.
Ensure that cable connections do not lie in the
bilge. Secure the cable(s) at regular intervals.
6-4 Power and transducer connections
Through hull transducers
Through hull transducers are supplied with ‘Y’
adapter cable for connection of both transducers
into the blue connector.
the plugs left in the boat are not exposed to the
elements. Push the attached dust covers over
the exposed ends of the plugs. Keep the display
unit in a dry clean place such as the optional
Navman carry bag.
