DUAL CHANNEL OPERATION
The ICS NAV5plus is a dual channel receiver.
The and keys on the keypad are used to switch the LCD display
between RX-A (the standard 518 kHz receiver) and RX-B (the 490 kHz
second receiver ).
The LAST MSG display shows the identity number of the last message
received on that receiver and the two-dot signal indicator will flash if there is
a signal being received from that receiver.
• Pressing and will display the corresponding information for the
other receiver.
Notes:
Although the and keys are used to select which receiver is shown
on the display, it is important to realise that both receivers are actively
receiving signals all the time.
If messages are being transmitted at the same time on both channels, both
messages will be received and printed.
Messages from RX-B are identified separately on the printout.
Only messages from the 518 kHz receiver channel will be present on the
RS422 serial output.
