Procedures of pairing  
What is pairing?  
BLUETOOTH devices need to be  
“paired” with each other beforehand.  
Once BLUETOOTH devices are  
paired, there is no need for pairing  
again, except in the following cases:  
• Pairing information is deleted  
after repair, etc.  
1 Place the connecting  
device within 1 m (3 ft)  
of this unit.  
2 Press and hold the  
POWER button for  
7 seconds or more to  
standby for pairing  
while the unit is turned  
off.  
• This unit is paired with 9 or more  
devices.  
This unit can be paired with up to  
8 devices; if a new device is  
paired after 8 devices have been  
paired, the device whose latest  
connection time is the oldest  
among the 8 paired devices is  
replaced by the new one.
