Frequently Asked Questions - 1943C-BB FURUNO
What is the maximum radar range of the Furuno 1943C-BB?
The radar can detect and display targets up to 72 nautical miles, depending on target size, atmospheric conditions, and antenna height.
Can I use the 1943C-BB as a fish finder?
Yes, the system supports an optional fish finder transducer (e.g., Furuno 525T-PBD) that can be connected to the existing sounder interface for depth and bottom plotting.
How do I perform a factory reset?
Press and hold the MENU key for 3 seconds, then select 'System Setup' and choose 'Factory Reset'. Confirm with the 'OK' button. This restores all settings to default.
What charts are compatible with this unit?
It accepts Furuno chart cards (Minicard format) and also supports C-MAP MAX cartography. Insert the card into the chart slot on the front panel.
Can I connect the 1943C-BB to a PC for software updates?
Yes, via the serial (NMEA) or network port. Use the Furuno 'NavNet vx2' updater software and an appropriate cable to install new firmware.
What is the power consumption in standby mode?
In standby mode, the unit consumes approximately 15 W. When the radar is transmitting, it draws about 60 W at nominal input voltage.
Is the display suitable for open-bridge installation?
The front panel is rated IPX6 (protected against powerful water jets), so it is suitable for flush mounting on an open bridge. It is recommended to install it with a protective sun cover when not in use.
How do I interpret radar returns and adjust the gain?
Begin with Auto Gain and then fine-tune using the GAIN rotary. Sea clutter should be adjusted separately. A well-calibrated radar shows clear landmasses and isolated echoes without excessive noise.
Can the radar be operated in dual range mode?
Yes, press the RANGE key twice to activate dual-range display, allowing simultaneous short and long range views on the same screen.
What kind of antenna is included with the 1943C-BB?
The package typically includes a radar dome antenna (model 1934 according to original specifications). This 4 kW dome provides a 2-foot array for reliable target detection.
