• North Indicator—toggles the north indicator arrow on or off.
• timed transmit—used to save power, usually while at anchor.
When Timed Transmit is On, the radar uses the settings in
timed transmit XMIt time and timed transmit StBY
time fields. When Timed Transmit is Off, these fields are
unavailable.
• timed transmit XMIt time—sets the amount of time (in
minutes) for which the radar transmits. For example, if set to
01 min, the radar transmits for one minute before switching to
standby for the amount of time entered in the timed transmit
StBY time field.
• timed transmit StBY time—sets the amount of time (in
minutes) that the radar is in standby mode. For example, if set
to 10 min, the radar is in standby mode for 10 minutes before
switching to transmission for the amount of time entered in
the timed transmit XMIt time field. When the radar is in
standby mode, the scanner does not rotate or transmit; however,
power is still applied to the Magnetron, eliminating the need
for a warm-up cycle.
• Cross-talk Rejection—toggles cross-talk rejection on or off.
Radar cross-talk may occur when two or more radar equipped
vessels are operating in proximity to one another. Cross-talk
rejection automatically filters out the cross-talk interference.
