To select the telemetry sensor settings, rotate the Rolling

Selector and place a box around Tele- SPEED then press

the Rolling Selector. The surrounding box will flash.

Rotate the Rolling Selector to select the desired sensor

settingforadjustmentthenpresstheRollingSelector.

Use the Rolling Selector to select the sensor parameters

toadjust.

Press the Rolling Selector and a surrounding box will

flash.

UsetheRollingSelectortoadjustthevalueandpressthe

Rolling Selector to select.

To return to the main screen press and hold the Rolling

Selector for more than three seconds.

Tele-SPEED

Zoom - The Zoom setting sets the maximum range or

boundary of the Speed unit.

Unit -Select RPM, MPH, KM/H display units

RollOut-TheRollOutfunctionisonlyvisiblewhenthe

unit is set to MPH or km/h and is the internal calculator

that allows rpm data to be converted to mph or km/h.

WhentheRollOutvalueissetto1.0,thedefaultsetting,

the value displayed on the main screen and stored in

maximum speed, is true rpm of the shaft gear or flywheel

that the rpm sensor is hooked up to. In order to program

the unit to display speed in mph, a conversion factor is

needed. Following are two methods of determining the

conversion factor.

Method A

• Marktheclutchbellthatthesensorisreadingfrom

with a small reference mark. A marker works well.

• Setthecarnexttoarulerandat0”thenrollthecar

forward by hand, counting each revolution of the

reference mark. At exactly 10 revolutions stop the

car.

• Measuretheexactdistancethatthecartraveledin

ten revolutions and divide this distance by 10 (e.g.

12.0” divided by 10 = 1.20”).

• AdjusttheRollOutvalueuntil1.20appearsonthe

screen. Now all the rpm related functions will be

displayed in mph or km/h.

Method B

For this method you either need to know the internal gear

ratio (normally provided in the vehicle’s manual) or be

able to calculate the ratio via the number of teeth on the

gears. It is also necessary to calculate the circumference

(distancearound)thetire.Oncetheinternalratiois

known, and the circumference in inches has been

determined, simply divide the circumference by the

internal ratio and use this value as the conversion.

To calculate circumference—multiply 3.14 x the tire’s

diameter in inches.

To calculate internal gear ratio—divide the larger gear

by the small gear. With multiple gear transmissions, it is

necessary to multiply each of the larger to smaller gear

reduction ratios to arrive at the final ratio.

Note: The Telemetry screen displays the

maximum recorded speed from the point

that the receiver was turned on. To reset the

maximum recorded speed, it is necessary to

turn off the receiver, then back on.
