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.
