• Be careful not to pay excessive attention to the main unit LCD while riding, otherwise you may have an accident.

• Do not use this product if you are using a heart pacemaker.

• This product is not a medical device. Data values should be used as references only.

• Button batteries which have been removed after use should be kept in a safe place out of the reach of children to avoid accidental swallowing. If batteries are swallowed by mistake, seek medical advice immediately.

• Do not use any batteries other than those specified. If the batteries explode or leak, fire, personal injury or damage to surrounding objects may occur.

Note:

* Equipment such as high-voltage power lines, signal devices, trams,

personal computers and LED lights may affect the cycle computer and

cause the heart rate to display incorrectly. * Handle each unit carefully, and avoid subjecting them to any shocks. * Avoid leaving the units exposed to extremely hot weather conditions for

long periods. * The units are designed to be fully waterproofed to withstand wet

weather riding conditions; however, do not deliberately place them into

water. * Never disassemble any of the SC-7900 components, as they cannot be

reassembled. * The AC switch is used to clear the date and time information. * Do not use thinner or other solvents to clean any of the components.

Solvents may damage the main unit and sensor surfaces. * To clean these parts, wipe them with a cloth soaked in a weak mixture of

neutral detergent and water. * Natural wear and deterioration which occurs as a result of normal use is

not covered by warranty. * If the button batteries are used incorrectly, they may leak or explode, so

make sure you observe the following points.

· Use only the specified batteries. Other types of battery cannot be used.

· Remove the batteries if they are not going to be used for long periods.

· If the batteries can no longer be used, they should be removed immediately.

· Do not recharge the batteries.

· Insert the batteries so that the + and – sides are correctly aligned.

· Never throw the batteries into fire.

· Used batteries should be disposed of in accordance with local waste regulations.

* None of the parts of the SC-7900 are interchangeable with the previous

FLIGHT DECK system, and cannot be used in conjunction with them.

* Because each unit is connected wirelessly, a small amount of time lag

may occur with displays.

Display can switch to show a variety of traveling data. (Page 25)

The travelling data such as travelling distance, travelling time, heart rate, calorie consumption, altitude and slope is displayed on the main unit LCD.

Automated stopwatch counter (Page 40)

The stopwatch counter can be started and stopped automatically by detecting the bicycle speed.

Remote operation from ST/SW (Page 25, 42)

Switching the display and recording lap data can be carried out by remote using the dual control lever.

Units are paired and connected wirelessly (Page 11, 21, 22)

The speed sensor, heart rate sensor unit and ST wireless units (optional) can be connected wirelessly. Up to a maximum of four bicycles can be registered in a single main unit. The main unit can be shared between the registered bicycles, and you can change which bicycle you ride.

Managing your heart rate (Page 35, 36)

You can specify the minimum heart rate and maximum heart rate to use as targets for indicating your level of activity. If your heart rate goes outside the set limits, the main unit can notify you by means of a buzzer and the heart rate value flashing on the display.

Checking the display in dark places (Page 22)

Backlight illumination lets you check the information appearing on the LCD even in dark places.

Managing data using a computer (Page 43)

Communication between a personal computer and the main unit is possible by means of a USB dongle (optional). This can be used to retrieve traveling data from the main unit, display this data in the form of graphs, change main unit settings and update the main unit software.

up setting mode. (For details on starting up setting mode, refer to page 26.)

(2) Select “SETTING” in the main menu. Then

select “PAIRING” in the Setting menu so that the pairing confirmation screen is displayed. If pairing has not yet been carried out for a particular unit, “–“ will appear beside the name of the unit. If pairing has already been carried out for a unit, “

™

”

will appear.

Pairing setting method

4. Pairing Function

In order for the main unit to display information from each of the sensors, the various units must first be registered with the SC-7900 system. This is called ‘pairing’. * If a unit is replaced or added, carry out pairing again for all units.

(3) When you press the select button (▼retry) on the main unit, the main

unit will switch to pairing standby mode. While the main unit is in pairing standby mode, insert the battery into the unit to be paired. * The units will switch to pairing mode for 30

seconds after their batteries are inserted.

* The SM-EW79F-E/I will switch to pairing mode

for 30 seconds once the battery for the gear shifting system has been connected.

(4) Press the select button and the set button on

the main unit simultaneously within the 30 seconds that the unit to be paired is in pairing mode. “SCANNING” will appear in the data display and pairing will then start.

(5) When pairing is complete, “™” will appear beside the name of the unit

which has just been paired. If you press the select button, the main unit will switch to pairing standby mode. You can then continue to carry

1312

(6) Repeat steps (3) and (4) for each unit until all units have been paired.

(7) Once pairing has been completed for all units, press the set button

(exit▼) to exit the pairing operation. * If multiple SC-7900 users carry out pairing simultaneously, the units

for other users may become paired with your own system. In order to make sure that pairing is carried out correctly, do not carry out pairing near any other users who are also carrying out pairing, or near any other devices which may operate wirelessly.

* After pairing has been completed, each user should check to make

sure that pairing has been carried out correctly.

* The st-R and st-L (ST wireless units) are optional. * The ST wireless units will start operating once bot the left and right

units have finished being paired. They will not operate only by themselves.

(SM-EW79F-E/I) (SM-SC79)

out pairing operations for any other unit which has not yet been paired. * Do not press the set button (exit▼) until

pairing has been completed for all units.

Main unit Battery used: CR2450 (x1)

5. Replacing the Batteries

Insert so that the + side is facing upward as shown in the illustration, and then close the battery cap.

CAUTION:

• Always be sure to set the main unit to sleep mode before replacing the main unit battery.

• If you replace the battery without setting the main unit to sleep mode first, the main unit will start up in initialization mode. * For details on initialization mode,

refer to page 20.

• If the low battery indicator appears in the main unit display, replace the battery with a new one straight away.

• If carrying out pairing between the main unit and the other units, batteries must be inserted into the other units too. * Refer to page 11 for details on pairing.

■

Speed sensor Battery used: CR1632 (x1)

CAUTION:

• If the speed is not being displayed correctly in the main unit display, repeat the pairing operation. If this still does not solve the problem, replace the speed sensor battery with a new one.

• When replacing the sensor unit battery, remove the old battery, and then wait until about 10 seconds have passed before inserting the new battery.

Open

The batteries for units other than the main unit should be inserted when the units are being paired.

In order to increase the operating life of the battery, it is recommended that you set the main unit to sleep mode after use so that it consumes less power. (For details on sleep mode, refer to page 19.)

The heart rate sensor unit will operate and battery power will be consumed if the electrodes are touched, even if it is not fitted to your body. In order to avoid battery power being consumed unnecessarily, remove the heart rate sensor unit and set the main unit to sleep mode immediately after use.
