OVERRIDE
When operating conditions are outside the normal preset limits, the radio will
revert to low power (approximately 75 Watts). The display’s “LOW” indicator
will light to indicate this condition. If this
should occur during an EMERGENCY
situation, pressing
will override the monitoring sensors and allow
FULL output power. The radio will stay in the
EMERGENCY OVERRIDE condition until the
radio power is re-cycled. If the power has been reduced manually or the tuner
fails to match the antenna, the override will not increase to full power.
SQUELCH OPERATION
Use the key to toggle the squelch
on / off. The “SQL” indicator shows the
squelch is on. The speaker will mute after
approximately 2 seconds. Varying audio
frequencies will open the squelch but not a
steady tone.
CLARIFIER OPERATIONS
In the “MARINE” operating system, the
clarifier tuning range is limited to
±
200 Hz
when used on any Bin or ITU/SEA channel.
When the radio is turned on, the clarifier step
size will default to 10 Hz.
Any “receive only” frequency or any frequency
used in the “AMATEUR” operating system has
an unlimited clarifier range and can be changed
in steps of 10 Hz, 100 Hz, 1 KHz, or 10 KHz.
To change the clarifier resolution
:
Select “1” for 10 Hz steps, “2” for 100 Hz
steps, “3” for 1 KHz steps or “4” for 10 KHz
steps then “UP” or “DN”.
e.g. Press or to have the clarifier change in 100 Hz steps.
The chosen clarifier digit will blink for 2 seconds to indicate the selection. If the
digit does not blink, it is not a valid selection for the current mode and the
setting will not change .
