DUGAS ENGINEERING WatchDog 2000 User manual

The following conventions are used in this manual:
• Quoted capital letters indicate what you will see on the WatchDog
2000 display.The actual display may use both capitals and
lowercase letters. For example, “SEE SPDS” indicates the following
will be shown on the WatchDog 2000 display.
Some letters cannot be displayed in their true form. For instance,
K’s cannot be formed, so K’s will look like capital H’s. Therefore H’s
are always represented in lowercase on the display. Also, an “m”
requires two digit fields to represent it in the display. For example,
“KEYTIME” on the display looks like:

CHAPTER 2
The WatchDog 2000 caters to the serious enduro rider, and to the
enduro rider wanting to improve his or her ability to race competitively,
accurately and with more finesse. The WatchDog 2000 allows the rider
to concentrate more on riding technique by alleviating the mental strain
of keeping track of your minute, your speed, and programming.
The display during race-mode shows you only the critical information
that you need to know to stay on time. Within your minute, DE’s
MinuteMinderTM technology displays at once the distance to the next
whole minute, differential time and keytime seconds. All the information
you will need in a glance, to keep an edge on your competition is on
your display! Outside of your minute, MileMinderTM displays the full
odometer and time differential.
WatchDog 2000 allows adjustments of all race variables while in race-
mode, including your mileage, your minute (for Brand-X), clock and tire
size. In the event your sensor magnet gets sheared off, WatchDog’s
exclusive ICD (Interactive Calculated Distance) mode will track your
“should-be” distance while allowing you to adjust the mileage at trail
markers so you can still monitor your early/late status. In addition,
Race Recovery allows you to advance to any keytime and mileage
should you need to exit race-mode to adjust any programming (like
speed changes or resets) during a race. Resets to zero allow
programming for multiple loops.
The all-aluminum color-anodized WatchDog 2000 off-road computer is
designed for ease-of-use, during both programming and race-modes.
The user does not need to have any technical experience to use or
program the WatchDog 2000.

CHAPTER 3
Tools needed for Installation
Your WatchDog 2000 is very easy to install. A typical installation will
require:
• Phillips screw driver.
• 9/64” hex key wrench
• 3/16” and 17/64” drill bit and 5/16 x 24 tap
• a drill bit, sized to clear your handle bar clamp bolts.
Other tools may be needed depending on your specific installation.
Mounting WatchDog 2000
WatchDog 2000 comes with two brackets for mounting your computer
to the handle bar clamps. The brackets can accommodate a wide range
of center-to-center clamp distances.
With the tabs facing out the brackets accommodate clamps up to 4”
apart. By flipping the bracket over so the tabs face inward, the center-
to-center distance is increased to 5”. The brackets are shipped w/o
holes for the handlebar bolts. This way you can customize the
bracketsso that WatchDog 2000 clears other accessories, such as
steering dampers. The brackets can be mounted on the front or back
handlebar clamp bolts, facing forward or backwards. If you want
WatchDog 2000 to sit directly above the handlebar, mount the brackets
to the front clamp bolts with the slots towards the rear.

Use spacers between the bracket and clamp so that you have access to
the bottom of the bracket for the nuts. Always drill the hole in the
bracket tab as near as possible to the computer. Cut or grind off any
unused portion of the backet tab if neccessary.
Locate the brackets by loosely assembling the WatchDog 2000 to the
brackets using the four cap screws and nuts provided. Position the
WatchDog 2000 where you want it. Adjust the brackets and mark the
position of the holes in the bracket. Drill the holes and mount the
brackets to the handle bar clamps. You may have to use longer
handlebar clamp bolts if you use spacers below the brackets. Tighten
the WatchDog 2000 to the brackets.Once the WatchDog 2000 is
mounted, run the switch wire along the handle bar and secure with zip
ties. Mount the switch next to the left grip. Adjust the position of the
switches so they are comfortable to access. If necessary, move the kill
switch so that the kill switch wire does not run near the thumbswitch
wire.
Connecting the Sensor Wire
The sensor is threaded for a 5/16 x 24 thread. The best way to mount
the sensor is to drill and tap a hole in the caliper carrier. If you use this
method, locate a spot for the magnet first. Find a location on the front
disk that passes by the caliper carrier but does not interfere with the
pads and mark it with tape or ink. Locate a spot on the caliper carrier by
which this mark will pass. Drill a 3/16” hole thru the carrier and into the
disk where you marked it (just spot drill the disk for now). Rotate the
disk and drill the hole about 1/64” deep in the disk and epoxy the
magnet in the hole. Drill out the hole in the carrier to 17/64ths and tap it
with the 5/16 x 24 tap. Remove one of the nuts from the sensor and
gently thread the sensor into the caliper carrier until the sensor is about
3/16 of an inch from the magnet as it goes by. DO NOT FORCE
SENSOR. IF TIGHT, RECUT THREADS AND USE OIL. Hand tighten
the outside nut against the caliper. Run the sensor wire up along the
brake line securing with ties or tape. Run the sensor cable all the way to
the brake master cylinder. DO NOT route the wire from the brake line
directly across to the computer as this will quickly destroy the wires
when the forks compress. By running the wire all the way to the master
cyclinder there is no stress on the wire as the forks and brake line
move. Connect the sensor to the computer. Neatly bundle up the slack
in the cable and secure it and the connector with ties to the handlebars.
When done, the connector should not move at all when forks are
compressed.

CHAPTER 4
This section describes and illustrates how to use the three buttons of
the thumb switch to program your race data. Once you are comfortable
with entering data and understand their functions, proceed to the
QuickStartTM chapter to program WatchDog for a race.
Thumb Switch Programming
In general, when using the thumb switch to program WatchDog 2000,
the MAIN button (top) is used to select functions or values while the UP/
DOWN buttons are used to scroll through the functions or values.

Use the UP/DOWN buttons to scroll to “RESET”. Select the reset
function by hitting MAIN. The display will read “AT 0_ _. _ _”, prompting
you for the AT mileage of the reset. The zero indicates the current digit
being edited. Use the UP/DOWN buttons to scroll through the numbers
0-9. Hit MAIN to select the currently displayed value for that digit field.
The current digit will be accepted and the cursor will move to the next
digit field. Continue entering the values for the remainder of the digit
fields. When the last digit is entered, the display will change to
“TO 0 _ _ . _ _”, prompting you for the TO mileage of the reset. Enter

a confirmation prompt will be displayed, (“ENTER?”). To accept the
entered reset values hit MAIN. This will store the values in memory. To
cancel entry hit DOWN. The reset function will be displayed again. To
continue entering resets hit MAIN and repeat.
At any point while entering the reset you can exit back to the start of the
function by holding the MAIN button until “OFF” is displayed and then
releasing. This will take you back to the beginning of the current
function.
Function Prompts
The following sections illustrate the prompts you will see for each
function. Enter the values for each function as described in the previous
section for entering resets. Parenthesis indicate valid value range.

when prompted for the speed in step 3 above. The following will be dis-
played “FOR 0_ _” prompting you for the duration in minutes. Enter
the duration and hit MAIN.
Note: If a dash appears next to SPD CH or RESET (ie “RESET -”) this
indicates that the resets contain a jump (reset to 000.00) and that the
entries will not be sorted by mileage.
Note: Layovers are stored as speed changes, with the speed = 0 mph.
They are sorted just as other speed changes are. When viewing
speeds they appear as “SPD 0 - XXX” where XXX is the duration in
minutes.

4. Hit MAIN to enter the next mileage and repeat step 3 for successive
mileages, or hit UP/DOWN to advance to “KEYTIME”.
Note:When multiple loops are programmed, you must verify to the end
of each loop in order. For example, if there are resets to zero at 45.00
and then 35.00 miles, first verify to 45.00 miles. Then hit MAIN again to
enter and verify to 35.00 miles.
This incremental verification can be used with all programs (to help find
programming errors, for example).
To abort a verify calculation hit MAIN while “HOLD ON” is displayed.

Editing Race Data
Data Entry Errors
If you make a mistake while entering resets, speed changes, tiresize,
keytime, verify mileage, start time, or your minute, simply press and
hold the MAIN button until “OFF “ is displayed then release MAIN. This
will bring you back to the start of the current function. No data will be
saved.
Adding Resets and Speed Changes
For single loop races (no resets to zero) you can add resets and speed
changes to your program by simply using the RESET and SPD CH
functions. The reset and speed changes are sorted by mileage and can
be entered in any order.
If there is a reset to zero in your program you can insert resets and
speed changes using the SEE RSTS and SEE SPDS functions. To
insert a reset, select the SEE RSTS function and hit MAIN until you see
the reset before which you want to insert a new reset. Hit the UP button
and “INSERT ?” will be displayed. Hit MAIN to insert a reset and then
enter the reset as usual. Hit UP or DOWN to cancel. Follow the same
procedure using SEE SPDS to insert a speed change.
Deleting Resets and Speed Changes
You can delete speed changes and resets using the SEE SPDS and
SEE RSTS functions. Select the desired function and use MAIN to
view the entry you want to delete. While you are viewing it press and
hold MAIN until “OFF” is displayed, then release MAIN. “DELETED”
will be displayed briefly and then the next entry will be displayed as
usual.
14
Programming for Multiple Loop Races
For multiple loop races where the mileage is reset to zero at the start of
each loop you must enter the resets and speeds in the order in which
they occur. Always do the resets before the speeds and enter a reset
to zero at the end mileage of each loop. Once you enter a reset to zero
the sorting feature is disabled and all subsequent resets (and speeds)
are stored in the order in which they are entered. If you did the speeds
first they would be sorted by mileage. A dash next to the function
(“RESET -”) indicates sorting is disabled. For example, if the first loop
is 40 miles long, enter a reset AT 40.00 TO 000.00. Then, a reset in
the second loop is entered after the reset to zero:
AT 034.00 TO 034.50
AT 040.00 TO 000.00 (end of first loop/start of next loop)
AT 010.20 TO 012.00
After the resets are entered, enter all the speed changes in the order in
which they occur. If there is a speed change at the start of the next loop
(at mile 000.00), you can enter that speed change at the same mileage
at which you entered the reset to zero or you can enter it at 000.00.
(where it occurs looks more obvious as you view your speeds if its at
the reset mileage). For example you can enter it as follows:
AT 000.00 SPD 024 (start of first loop)
AT 024.00 SPD 036
AT 040.00 SPD 018 (end of first loop)
AT 018.00 SPD 024
or
AT 000.00 SPD 024 (start of first loop)
AT 024.00 SPD 036
AT 000.00 SPD 018 (start of second loop)
AT 018.00 SPD 024
You can have multiple speed changes at the same mileage. For exam-
ple, if there was also a layover at 040.00, you could enter it at 000.00 or
at 040.00 and you could enter it before or after the speed change if the
speed change is at the same mileage. Or you could put the speed
change at 040.00 and the layover at 000.00.....etc.
Once the resets, speed changes and layovers are programmed, they
can be easily viewed, checked and edited by selecting SEE RSTS and
SEE SPDS.
13

5. Enter Keytime
Once all the data has been entered correctly, scroll down to
“KEYTIME”, hit MAIN. Enter a time 10 or 15 seconds ahead of the
posted keytime (this provides sufficient time to synchronize
WatchDog with keytime). When the posted keytime reaches the
entered value hit the MAIN button. After you press MAIN the
display will continue to show the running keytime and WatchDog
2000 will begin the countdown to your race time. Press the DOWN
button to view the countdown time. You can scroll through the
menu as usual after entering keytime. Anytime you go back and
change your minute or start time, the countdown stops until a new
keytime is entered. Also, once keytime is entered, the CLR RSTS,
CLR SPDS, and VERIFY TO functions are disabled and are not
displayed. These functions can be re-enabled by resetting your
minute, start time, or by turning off the computer and then turning it
on again. Remember: Always enter the posted keytime directly.
WatchDog will adjust for your minute and the race start time when
displaying the countdown.

CHAPTER 5
WatchDog 2000 was designed to simplify timekeeping before and
during a race. To start a new race with WatchDog 2000, use the
following QuickStartTM procedure.
1. Power On Battery Check
Press and hold MAIN button until “ON” is displayed, release MAIN.
A battery check will be perfomed and displayed (“BATT 99 “). The
range is from 0 to 99. Change the batteries when the charge is
around 25. To exit the battery check press any button. “RESET” will
be displayed.
2. Program Resets and Speed Changes
Clear old resets and speed changes by scrolling down to the CLR
RST/CLR SPDS functions. Hit MAIN at each function to clear the
resets and speed changes. Enter all the resets, speed changes,
layovers, and jumps as outlined on your route sheet. If the first
speed is not 24mph you must enter a new speed for 000.00
miles. Speed changes and resets can be entered in any order.
WatchDog 2000 will sort them by mileage. Error checking
disallows certain invalid entries. For instance, you can’t enter a
reset from 11.50 miles to 10.50 miles.
3. Enter Tiresize, Minute and Race Start time
Use the TIRESIZE, MINUTE, and STRT TM functions to enter your
tire size, your start minute, and the race start time (i.e., 9:00).
4. Verify Programming
Scroll down, using the DOWN button to “VERIFYTO” and enter the
last mileage indicated on your route sheet. See page 16. Hit the
MAIN button. “HOLD ON” will appear on your display. When done
(usually about 1sec/3miles) WatchDog 2000 will display the
calculated time for the entered mileage. It should match your route
sheet. If not, make sure the speed changes match the route sheet.
For multiple loops you must verify to the end of each loop in order.
For example, if you have a reset to zero at 45.00 miles, first verify to
45.00. Then hit MAIN and enter the mileage at the end of the next
loop, etc. This routine does not check the resets so you need to
make sure they are correct as you view them. To abort a verify
calculation hit MAIN while “HOLD ON” is displayed.

If the count is low but you can see ahead enough, it is safe to keep
going until the count down approaches zero again (don’t forget to adjust
your mileage at the markers).
The two center digits indicate your early/late status. Use this as the
main indicator of how you are doing. Always use this in conjunction with
the keytime seconds (right most field) when approaching checkpoints. If
you are late the minus “-” sign appears around the differential time (DT)
If you are early the DT flashes. If you are less than a minute early or
late the DT is displayed as second, ie “23 -45- :21”, indicating 45
second late. If you are more than a minute early the DT is displayed as
minutes and tenths of seconds, ie “12 1:2 :44”, indicating one minute
and twenty something seconds early
The right most digits display the keytime seconds. This is used as a
final check before entering checkpoints. A diff time equal to 00 should
not be used alone as an indicator of when to enter a check, since this is
dependent on the accuracy of your odometer. Always use the keytime
seconds as the last indicator of when to enter the checkpoint. Enter as
the seconds roll over to zero, or at 30 seconds for an emergency check.
MileMinderTM
When you are more than ten minutes early or more than one minute
late the MileMinderTM displays two fields of information.The left field
displays your mileage in miles and hundreths of a mile. The right field
displays your DT in minutes and seconds. Go faster if you are late. Go
slower if you are early!

CHAPTER 6
There are two main displays when you are racing. AUTO mode
automatically selects what is displayed depending on your early/late
status. WatchDog’s MinuteMinderTM is displayed if you are less than
ten minutes early or less than one minute late. When you are more than
one minute late WatchDog’s MileMinderTM is displayed. While racing,
you can also adjust your mileage, your minute, keytime, and tiresize.
You can also use Interactive Calculated Distance (ICD) mode.
MinuteMinderTM
The MinuteMinderTM displays three fields of information. The two left
digit fields indicate the countdown distance to where the next whole
minute should be. (remember, checkpoints can only be on whole
minutes). If the distance is less than one mile it is displayed in
hundredths, ie “88 -45- :23”, indicating 0.88 miles or 88 hundredths. If
the distance is more than one mile it is displayed as miles and tenths of
miles, ie. “1.3 -44- :52”, indicating 1.3+ miles. The initial countdown
value is dependant on the currently programmed speed average, for
example, at 24mph it will count down from 40 to 00, then start at 40
again; at 18mph it will count from 30, etc. Use this information wisely to
get a early jump into sections. As long as the count is high you can ride
hot into the section. As the countdown gets close to zero, be careful. If
the count will reach zero around the next blind corner don’t be early!!! If
you are early, wait until the differential time is close to 00, then proceed
carefully. Don’t burn a check!!

View/Adjust Keytime
From AUTO mode, you can view the current keytime by pushing
MAIN twice, three times if running Brand-X rules. You cannot change
the keytime from this display . If you need to change keytime, press
and hold the MAIN button until “CLOCK” appears on the
display. Release the button. A “C” will be displayed on the left indicating
keytime can be adjusted. Adjust the keytime in increments of minutes
using the UP/DOWN buttons. The seconds are reset to zero each time
you change the minute. Hit the MAIN button to return to AUTO mode.
When you adjust your keytime in this mode you need to enter the
elapsed keytime since leaving the gate. If your backup watch displays
elapsed time then you can use this time directly. If it shows the actual
posted keytime you must subtract your minute before using it.
For AMA events, simply enter the time directly from your backup watch.
When running Brand-X, first set your minute to your original minute,
then adjust the clock to match your backup watch. After adjusting the
clock set your minute to your current minute.
Whichever rule you are running, adjust the clock so that the full minutes
match the backup watch. For example, if the backup shows 1:23:35,
set the computer clock to 1:23:00. When the backup seconds turn to
:00, increment the clock minute. Make sure they match then hit MAIN to
return to race displays. Adjust your minute if necessary.
Note: In Brand-X the keytime you see once back in race mode is
adjusted for your current minute. You can compare this directly to your
route sheet.
Adjusting Tire Size
At any time, to adjust your tire size, hold down the MAIN button until
“TIRESIZE” is displayed. Release the button. Now use the UP/DOWN
buttons to adjust your tire size in increments of 0.01 inches. Hit the
MAIN button to return to AUTO mode.
Tip: If your mileage is off by one one-hundredth (1/100) of a mile over
the course of a mile, adjust your tire size by about 0.80 inch.
Interactive Calculated Distance Mode (ICD)
In the event your magnet gets sheared off (or anytime), you can still use
WatchDog 2000 to display your differential time and calculated mile-
age. To enter ICD mode, press and hold MAIN button until “ ICD ON ”
is displayed. Calculated distance will be displayed on the left, and differ-
ential minutes and seconds will be displayed on the right. You will
immediately see the mileage change until the diff time is zero. The diff
time will remain 0:00 until you adjust the mileage. When you adjust the

Other Race Mode Displays
The following sections describes other race mode displays and how to
adjust race variables.
Adjusting Mileage
In MinuteMinderTM there are two ways to view and/or adjust your
mileage. To view or adjust the mileage hit either the UP or DOWN
button. The display switches to MileMinderTM. Then use the UP/
DOWN buttons to adjust your mileage.
If you initially hit the UP button to enter MileMinderTM , the display will
return to MinuteMinderTM after 4 seconds of no button activity. If you
initially hit the DOWN button the display will remain in MileMinderTM
until you hit the MAIN button.
When you hit the UP or DOWN button the displayed mileage stops
incrementing except for when you adjust it. If you are still moving, the
mileage is accumulated in the background. A few seconds after you
are done adjusting your mileage the accumulated mileage is added to
the displayed mileage. This allows you to adjust your mileage to match
a trail marker even though you are still moving forward. Just make sure
that you begin adjusting your mileage when you are next to the trail
marker.
Tip: Use the UP button to quickly view your mileage and adjust if
necessary. Use the DOWN button on road sections or fast sections
when you stay within your minute and want a constant display of your
mileage.
Tip: The longer you hold the UP/DOWN button the faster the mileage
will scroll.
Changing your Minute (Brand-X)
To change your minute in Brand-X racing, hit the MAIN button once
from AUTO mode. Your minute is displayed. Use the UP/DOWN
buttons to adjust. The display will return to the AUTO mode display after
4 seconds of no button activity, or after 10 seconds if you did not adjust
your minute.
Note: In AMA rules, your minute will not be displayed. Hitting the MAIN
button will display odometer and speedometer.
Tip: The display will automatically return to AUTO mode so don’t worry
about the display, adjust your minute and take off!!
View Odometer and Speedometer
You can view your odometer and speedometer by pressing MAIN once
in AMA or twice in Brand-X. The speed is a 3 second running average.

mileage at a trail marker, the diff time will reflect your early or late
status. If you are late, after a short delay the displayed mileage will
return to the calculated mileage for the current keytime, and the diff time
will return to 0:00. If you are early, the displayed mileage will remain as
is until the diff time reaches 0:00. At which time the calculated distance
will begin to increment again and the diff time will remain at 0:00.
Since the mileage is automatically incremented in this mode, you
should not have to adjust the mileage too much at the trail markers.
With a quick mileage adjustment you can determine your diff time and
either take off again or wait.
Another use for ICD is during a gas stop or layover when you want to
monitor your remaining time but dont want the mileage to increment
(while driving around the pits for example). When you get to the gas
stop, enter ICD and set the odo to the desired mileage. For example,
set it to the mileage at the start of the next section (ie. known control
mileage). Then as you ride around you will not affect the remaining
duration of the gas stop. Caution!! Don’t forget to get out of ICD
when you get to the known control! To exit ICD hold MAIN until “ICD
OFF” is displayed, then release.
Race Recovery
In the unlikely event that the computer unexpectedly resets, (EMI noise
etc) WatchDog will either recover automatically or prompt you to enter
the keytime (“KEYTIME”). If the computer determines that no
information has been corrupted it will recover automatically. During this
time the computer will display “HOLD ON” while it returns to the
current mileage and keytime in the race. If your WatchDog has
determined that data has been corrupted it will prompt you to enter the
current keytime. Using your back-up watch (which you should always
have), enter the current un-adjusted keytime (the posted keytime). You
will then be prompted for an AT mileage (“AT 0 _ _._ _”). Enter the
mileage to which you want to advance. To enter a mileage past a reset
to zero, you must enter the total accumulative mileage to that point. For
example, if the reset to zero is at 30.00 miles and you want to advance
to mile 10.00 of the 2nd loop, enter 40.00 miles at the prompt. If you
make a mistake entering either value, hold MAIN until “OFF“ is
displayed. You will be prompted for the keytime again. WatchDog will
enter race mode and advance to the entered keytime and mileage.
Once back in race mode, adjust your minute if necessary. While
recovering, “HOLD ON” is displayed, during which you DO NOT need
to wait....GO!!
Note: This feature can be used at any time to enter race mode. If you
enter a post race-start keytime (keytime plus your minute) you will
always be prompted for a mileage.

CHAPTER 8
Sensor Check Mode
You can check to see if the sensor is working by entering a tiresize of
zero (000.00). This will not be stored in memory. The display will show
you the software rev level on the left and a hit count on the right,
ie “81 000”. As you rotate your tire, the count will increment every time
the magnet goes by the sensor. If the count does not increment, check
both the sensor wiring and the distance between the sensor and the
magnet. The magnet should be less than a quarter inch (1/4”) from the
sensor as it passes by. You can check intermitent problems by holding
the magnet on the sensor and wiggling the wires at the connectors.
Instant Race Mode
For recreational or practice riding (or panic race starts) you can
instantly enter Race Mode by entering a keytime of zero (00:00:00). All
the functions of Race Mode are enabled.
Tip: Use Instant Race Mode if you just need to use the odometer or
speedometer. Also use Instant Race Mode for practicing by
programming a speed average (using speed change function) and
using the differential time to maintain that pace. This is good practice for
using WatchDog 2000 and for improving racing skills.
Software Reset
In the event that you find a way to “hang” the software, there is an
escape sequence built in to WatchDog 2000. If your computer does
not seem to be responding to switch input, wait about one minute then
press the MAIN button for a few seconds. The software will reset itself
and return to the battery check. No programming information will be
lost.

CHAPTER 7
Measuring Tire Circumference
In order for the computer to accurately track your mileage you must
enter the circumference of the front tire. The computer then knows how
far you travel each time the tire rotates. The accuracy of your odometer
depends on the accuracy of this measurement. The caveat to this is
that you will probably need to adjust it again once on the trail to match
the odometer of whoever laid out the course.
There are several ways to measure this. The most accurate is to put
some paint on one of the center knobbies of the front tire and move the
bike through two tire rotations. Measure the distance between the first
and third knobby print and divide this distance by two. This is the value
you enter using the TIRESIZE function.
You can also mark the tire with a piece of tape. Rotate the tire so the
tape is at dead bottom. Mark the ground then move the bike through
two rotation and mark the ground again. Make the measurement as
described above.
Miles and MPH Display
If you want the computer to display distances in miles and speed in
miles per hour, measure and enter the tire size in inches and hun-
dredths of inches. Any value less than 150 is assumed to be in inches.
When you view your tiresize you will see “IN 084.88” indicating the size
is in inches.
Kilometers and Km/h Display
If you want to display distances in kilometers and speed in kilometers
per hour, measure and enter your tiresize in centimeters. When you
enter a value over 149.99 for tiresize, the computer assumes that the
value is in centimeters. When you view your tiresize you will see
“CE 214.43” indicating the size is in centimeters.
