FUNCTIONS
CLOCK
Cyclometer 25 only
You can reach the clock from any function by
holding the right button down for 2 seconds.
Press the right button to return to the last func-
tion displayed. The clock shows 24-hour time
in hours and minutes. After the Cyclometer 25
has received no wheel pulses or button presses
in 10 minutes, it goes to sleep and displays the
clock only.
SCAN MODE
Cyclometer 15 only
To scan in the Cyclometer 15 and show each
function for 5 seconds, hold the right button,
then press the left button in any function ex-
ceptTotalDistance.To exitthe scanmode, again
hold the right button and press the left button.
SPEED
Displayed in All Functions
Speed resolution is to 0.1 mph up to 19.9 mph,
0.5 mph from 20 to 39.5 mph, and 1.0 mph
above 40 mph. ‘mi’ flashes when the Cyclom-
eter is receiving speed and distance data from
the wheel sensor.
2. TRIP DISTANCE–d
Displays the distance (d) ridden since the last
reset up to 620.99 miles. At 621.00 miles it re-
sets to 0 and resumes accumulation. Trip Dis-
tance also resets automatically when the Ride
Timer reaches10 hours.Reset atthestart ofeach
ride to avoid automatic reset during your ride.
Press the right button to go to Average Speed.
3. AVERAGE SPEED–AV
Displays the average speed since the last reset.
Averages speed for up to 10 hours. After 10
hoursthe Cyclometer 15 displaysan ‘E’ instead
of Average speed. After 10 hours the Cyclom-
eter 25 resets automatically, then resumes aver-
aging.Thetimeover which theaverage hasbeen
calculated is shown in the Ride Timer.
Press the right button to go to Ride Time.
4. RIDE TIME–ST
Displays ride times (ST) up to 9 hours 59 min-
utes.Resetsautomatically at 10 hours. TripDis-
tance and Average Speed also reset at 10 hours.
Ride time is the time that the bicycle's wheels
have been turning. Time stopped is not accu-
mulated.Average speed equals the trip distance
divided by the ride time.
Pressthe rightbutton togoto MaximumSpeed.
5. MAXIMUM SPEED–MX
Displays the maximum speed reached (MX)
since the last reset up to 75.0 mph.
Press the right button to go to the Total Dis-
tance (Cyclometer 15) or Stopwatch (Cyclo-
meter 25.
1. TOTAL DISTANCE–D
Accumulates the total distance (D) you have
ridden up to 6,209.9 miles. At 6,210 miles it
clears to 0 and resumes accumulation. To
record yearly mileage, clear before your first
rideof a newyear.See‘AllClear’ onother side.
Press the right button to go to trip distance.
6. STOPWATCH–ST
Cyclometer 25 only
When the Stopwatch is displayed, ‘ST’ blinks.
Press the left button to start and stop the Stop-
watch (ST). Displays elapsed times in hun-
dredthsof a secondto 9 minutes59.99seconds,
then in hours, minutes and seconds to 9:59:59.
At10 hours it rolls overto0 and continues tim-
ing.Clearby holding the leftbutton then press-
ing the right button. The stopwatch can be
started, stopped, and cleared without affecting
the average speed of the entire ride.
Press the right button to go to Total Distance.

CALIBRATION
ALL CLEAR. You can clear Total Distance manually by holding down
the left button in the Total Distance (D) function until the test pattern
appears (10 seconds). This erases all stored data and resets the calibration
number to 2155 mm (Cyclometer 15). Calibration number is retained
with all clear in Cyclometer 25.

INSTALLINGANEWBATTERY.Tore-
move the battery, pry up the cap on the back
of the Cyclometer with a screwdriver. Install
the new battery with its positive (+) side to-
ward the cap, then press in the cap with your
thumb. Use only an Avocet Cyclometer 15/
25 battery or equivalent (see specifications).
Removing the battery erases all stored data
and resets the calibration number to 2155.
Afterinstalling a battery, the Cyclometerdis-
plays the test pattern briefly, then goes into
miles/kilometers setup.
SETTING THE CLOCK. (Cyclometer 25). Hold down the right but-
ton in any function to display the clock. Hold down the left button then
press the right button to reach clock adjust. The right digit will blink.
Change it with the right button. Press the left button to go to the next
digit. When you adjust the left digit, it will not change in the display.
You will have to confirm that this digit is correct after you exit clock set.
Ifitis incorrect, return to clockset, gotothe left digit, and adjust it again
with the right button. Note that you cannot set the clock when the Cy-
clometer 25 is asleep with only the clock displayed.
AUTOMATICPOWERSAVER.After nobuttons have beenpressed
and no wheel movement has been detected for 10 minutes, the display
will go blank (Cyclometer 15) or display only the clock (Cyclometer 25).

MILES OR KILOMETERS. Go to the Total Distance (D) function.
Hold down the left button for 12 seconds until the test pattern appears
and all stored data is cleared. Four seconds after releasing ‘mi’ or ‘km’
flashes. Press the right button to switch between miles and kilometers,
then complete calibration. With the Cyclometer 25 you can change be-
tween miles and kilometers without erasing stored data. Hold the left but-
ton in Total Distance (D) for six seconds and release when ‘mi’ or ‘km’
flashes. Switch between units with the right button. Stored maximum and
average speeds and distance data are automatically converted to the units
chosen when you use this method. Exit by pressing the left button.
PRECISE CALIBRATION. For the most precise calibration of your Cyclometer, measure the
tire's ‘rolling circumference’ by the following method: Inflate your tires to your usual riding pres-
sure. Mark the ground under the valve stem when the stem is at its lowest point. Get on the bicycle
and have a helper push you in your normal riding position until the valve stem returns to its lowest
point. Take care that the tire travels in a straight line. Mark below the stem again, then measure the
distance in inches between the marks. Multiply your measurement by 25.4 to convert your measure-
ment to millimeters and get your calibration number. Record numbers for your different bicycles
and wheels below.

CALIBRATION NUMBERS. The calibration number is wheel circumference in millime-
ters. This table is based on popular tire brands and assumes recommended inflation pressure and
arider weight of 165 lbs.(75kg). To account for youruniquecombination of weight, tirepressure,
and tire model, measure your tire circumference.

15: hold the left button until the calibration number 2155 shows in the
lower display and its right digit blinks (8 seconds). Cyclometer 25: hold the
left button until the calibration number 2155 shows in the lower display (4
seconds), release, then hold again 4 seconds until the right digit of the cali-
bration number blinks. Change the number with the right button. Press the
left button to go to the next digit. After adjusting all the digits, press the left
button to exit. To check the calibration number, hold the left button in Trip

SPECIFICATIONS
INSTALLATION
STEP 1– RECEIVER. Cut the clamp screw
off the receiver bracket with scissors. Position
the receiver on the right fork blade about 3"
above the hub. The receiver housing should be
parallel to a spoke positioned behind it. Insert
the screw and tighten it until the receiver stays
in position on the fork.
STEP 2 – TRANSMITTER. Remove the
screw from the transmitter magnet and install it
on one of the right-side spokes opposite the re-
ceiver. The magnet should line up over one of
themarksonthereceiver and not align between
the marks.
Rotate the receiver until it is1/8to 3/16" from the
transmittermagnet. Tightenthetransmitterand
receiver screws. Trim off excess receiver clamp
strap with scissors.
STEP 3 - RECEIVER WIRE. Attach the
wire to the inside of the fork with cable ties,
thenwrap the wire aroundthe front brake cable
until the excess has been used up. Attach the
wire only to parts that rotate when the bicycle
issteered–the fork, handlebar stem,or the front
brake cable. Do not attach the wire to the head
tube.
STEP 4 – MOUNT BRACKET. Wrap the
rubber shim around the handlebar near the
stem. Remove the clamp screw and place the
bracket on the handlebar over the shim. If the
shim is too long, trim it shorter with scissors.
Insert the clamp screw and tighten it until the
bracket is secure. Slide the Cyclometer into the
bracketfromfront to rearuntil it snapson.Spin
the wheel and confirm that a speed reading is
displayed. If the display remains at zero, check
that the receiver and transmitter magnet are
aligned and 1/8to 3/16" apart.
