6-7 Cleaning and maintenance
The FISH 4500/4600 screen is covered by a 
proprietary anti-reflection coating. To avoid 
damage, clean the screen only with a damp 
cloth and mild detergent when dirty or covered 
in sea salt. Avoid abrasive cleaners, petrol or 
other solvents.  
 
Cover or remove a transom-mounted trans-
ducer when repainting the hull. If painting over a 
through hull transducer with antifouling paint, use 
only one coat of paint. Remove the previous coat 
of antifouling paint by sanding it lightly.
To optimize performance, avoid walking on or 
jamming cables and connectors. Keep the trans-
ducer free of weed, paint and debris. Do not use 
a high pressure water blast on a speed sensor 
paddlewheel as it may damage the bearings.
When not in use, the FISH 4500/4600 can 
be removed from the installation bracket and 
stored in the Navman carry bag, or left on the 
installation bracket and securely covered with 
the sun cover supplied.
6-6 Systems of several instruments 
Several Navman instruments can be connected 
together to share data. 
The FISH 4500/4600 is particularly suited to 
work with the TRACKER 5500/5600 - Navman’s 
color display GPS chartplotter with worldwide 
coverage. 
There are two ways of connecting instruments 
together; NavBus or NMEA.
NavBus
NavBus is a Navman proprietary system that 
allows systems of multiple instruments to be 
built using a single set of transducers. When 
instruments are connected by NavBus:
• 
If the units, alarms or calibration are changed 
in one instrument, then the values will au-
tomatically change in all instruments of the 
same type.
• 
Each instrument can be assigned to a group 
of instruments. Then, if the backlight setting 
is changed in one group, it will automatically  
change for the other instruments in that group. 
However, the backlight setting will not change 
for instruments in different groups.
• 
If an alarm sounds, mute it by clearing the 
alarm on any instrument which can display 
that alarm.
NMEA
NMEA is an industry standard for marine instru-
ment connections. Data sent by one instrument 
over an NMEA line can be read and displayed 
by another instrument that accepts NMEA 
0183 Version 2. It is not as flexible as NavBus 
as it requires dedicated connections between 
instruments. 
Please contact your Navman dealer for informa-
tion on Navman’s full range of NMEA enabled 
instruments and connection options.
Repeater for depth, speed, water temperature and battery voltage. 
Accepts NavBus or NMEA data inputs from other instruments.
