•Easy-to-use
8 large buttons on the front panel provide convenient operation. The
independent volume and channel buttons are located on the front
panel for convenient one-hand operation.
PRECAUTION
•WARNING! NEVER hold the transceiver in such a
way that the antenna is very close to, or touching exposed
parts of the body, especially the face or eyes, while
transmitting. The transceiver will perform best if the
microphone is 5 to 10 cm away from the lips and the
transceiver is vertical.
•AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below –15°C or above +55°C.
•KEEP the transceiver out of the reach of children.
•KEEP the transceiver at least 1 metre away from your
vessel’s magnetic navigation compass.
•BE CAREFUL! The NX1000 is built to be fully
waterproof, corresponding to the IPX7 industry standard, (1
m depth for 30 min.). However, once the transceiver has
been dropped, waterproofing cannot be guaranteed due to
the fact that the transceiver may be cracked, or the
waterproof seal may have been damaged, etc.
•MAKE SURE the flexible antenna and battery pack are
securely attached to the transceiver, and that the antenna
and battery pack are dry before attachment. Exposing the
inside of the transceiver to water may result in serious
damage to the transceiver.

1 OPERATION RULES
1.1 Priorities
• Read all rules and regulations pertaining to priorities and keep an up-
to-date copy handy. Safety and distress calls take priority over all
others.
• You must monitor Channel 16 when you are not operating on
another channel.
• False or fraudulent distress calls are prohibited under law.
1.2 Privacy
• Information overheard but not intended for you cannot lawfully be
used in any way.
• Indecent or profane language is forbidden.
1.3 Radio licenses
1.3.1 Ship station license
When your craft is equipped with a VHF FM transceiver you must be
in possession of a current radio station license before using the
transceiver. It is unlawful to operate a ship station which is not
licensed. Inquire through your dealer or the appropriate government
agency for a Ship-Radiotelephone license. This license includes the
call sign that is your craft’s identification for radio purposes.
1.3.2 Operator’s license
A restricted Radiotelephone Operator Permit is the license most often
held by small vessel radio operators when a radio is not required for
safety purposes. The Restricted Radiotelephone Operator Permit must
be posted near the transceiver or be kept with the operator. Only a
licensed radio operator may operate a transceiver. However, non-
licensed individuals may talk over a transceiver if a licensed operator
starts, supervises, ends the call and makes the necessary log entries.
A current copy of the applicable government rules and regulations is
only required to be on hand for vessels in which a radio telephone is
compulsory. However, even if you are not required to have these on
hand it is your responsibility to be thoroughly acquainted with all
pertinent rules and regulations.
