»CoxBox Core and GPS are both completely compatible with all current NK
wiring, microphone, speaker, chargers and mounting cups.
»Attach the 5-pin receptacle end of your NK audio harness to the Audio
Connector Port. If present, be sure to align the rib on the receptable with the
notch on the Connector Port.
»Press the receptable straight in rmly to ensure a good connection.
Try not to twist the receptacle to avoid damaging the pins, sockets or plug.
»Since a rate sensor is no longer needed, you can remove the R harness and seat
magnet from your boat when using the new model. However leaving the rate
sensor attached will not cause any issues and you may want to keep it if you still
use older CoxBox Ampliers.
»Attach a NK R2 Microphone to the Microphone Connector Port to complete
installation.

Every stroke taken with the CoxBox running is stored in
memory and the memory can be reviewed in 100 meter
increments. The speed input (GPS or Impeller) and
system of units used will be stored as they were rowed.
Both impeller and GPS stats can be viewed upon export.
The total memory that the unit can store is approximately
25 hours.
»MEMORY STORAGE
When the memory is full, the unit will stop recording
data. When nearing or at full data, you must delete
all session data to continue recording (see below).
The amount of memory used can be found on the
bottom of the Recall Menu. An alert message will
appear when memory log is nearly full.
»DATA RECALL
Select Data Recall from the Main Menu to review
stored data. Recall memory will be formatted in
sessions according to date and time. Just Row
sessions will have the JustGo prex whereas a
Workout session will just show the pieces run.
Please note: a session is not complete until: a) In Just
Row, you reset the counter b) In Workout, the workout is
completed or cancelled.

»SPEED/DISTANCE SETUP
Options are Speed mode or Split mode. Speed mode will display your speed
in the top right window (which can be exed). Split mode will display your
pace expressed as a time to cover a 500 meter distance. Units allows you to
change the units shown for speed and distance (options are: M,M/S, /500M;
KM, KMH, /500M; or MI, MPH, /MI).
»AUTO PAUSE
If toggled ON, the unit will stop the timer if it does not detect a stroke within
the last 6 seconds. If toggled OFF, the unit will not stop the timer even if no
strokes are being detected. If you would like to stop the timer manually, select
the button to start and stop the timer manually.
Please note: the unit will not Auto Pause during the Rest sessions
of a Workout.
NOTE: Average Speed is always calculated as a function of the distance
covered in the elapsed time shown. Because the timer will continue to
run while you are not rowing, turning Auto Pause “OFF” will impact the
calculation of your cumulative average speed.
»AUTO SHUTDOWN
When Auto Shutdown is set to 10min, the unit will automatically shut off after
10 minutes of not detecting a stroke rate. If the Auto Shutdown is set to OFF,
the unit will only turn off when the user manually shuts the unit down.

»IMPELLER CALIBRATION
When using an impeller, this setting allows you to run the calibration routine and
enter a calibration value.
»GPS SPD SMOOTHING, STROKES
The Speed Smoothing feature will average the last number of strokes selected.
If “2” is selected, for example, the Speed/Split displayed will be an average of
the last two strokes, updated every stroke. If you decrease this number, the
speed value displayed will respond more quickly to changes in boat speed.
If you increase this number, the speed value will be more stable, but will take
longer to show changes in boat speed.
»STROKE RATE SETUP
Options are Timer Start Acceleration, Noise Filtering and Axis.
»TIMER START ACCELERATION
Governs the degree of acceleration that must be detected to start the stroke
meter. The default value is 4. If you increase this value, a more forceful stroke
is needed to start the timer. If you decrease this value, a less forceful stroke is
needed to start the timer.
»NOISE FILTERING
Governs the degree to which the accelerometer will register changes in
acceleration as a stroke. The default value is 3. If you increase this value, more
acceleration is needed to register a stroke. If you decrease this value, less
acceleration is needed to register a stroke.

added to this entry (i.e., Work1, Work2, Work3, etc).
»REST: Denes the amount of rest in between work
intervals. Rest can be time based or distance based.
The number shown to the right is the rest value
per the unit shown. Similarly if more than one rest
period is entered in a variable workout, it will be
followed by a number.
»NUMBER OF SETS: Select the number of sets
of the proceeding interval workout to run. For
example if you have a workout with a work and rest
