•

Keep the temperature of the soldering iron around 270 

°

C

during repairing.

•

Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

•

Be careful not to apply force on the conductor when soldering
or unsoldering.

•

Never reuse a disconnected chip component.

•

Notice that the minus side of a tantalum capacitor may be
damaged by heat.

Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.

•

Unleaded solder melts at a temperature about 40 

°

C higher

than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 

°

C.

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

•

Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

•

Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder. Operating instructiondd

Use only the supplied AC power adaptor. Do not use any
other AC power adaptor to avoid damaging the
transmitter.

By using the BLUETOOTH connection, you can listen to the sound from a BLUETOOTH
stereo audio source device with this unit wirelessly.

For details on how to operate the device to be connected, refer to the operating instructions supplied with
the device.

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.
• This unit is paired with 9 or more devices.

This unit can be paired with up to 8 BLUETOOTH stereo audio source 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.

• This unit is reset.

All pairing information is deleted.

Check the following before operating the unit.

– This unit is connected to a power source and the 1 indicator (green) goes off.

When the 1 indicator (green) and 

 indicator (blue) start flashing together, release the

button. This unit enters pairing mode.

Pairing mode is cancelled and this unit is turned off after about 5 minutes. If this unit is turned off
while performing the procedure, start over from step 

.

The list of detected devices appear on the display of the BLUETOOTH stereo audio
source device.
This unit is displayed as “SRS-BTM30.”
If “SRS-BTM30” is not displayed, repeat from step 

.

• When pairing, be sure to place both the BLUETOOTH devices within 1 m (3 ft) of each other.
• Some devices cannot display the list of detected devices.

*

Passcode may be called “Passkey,” “PIN code,” “PIN number,” or “Password.”

Some BLUETOOTH stereo audio source devices may connect with the unit
automatically when pairing is complete.
When the BLUETOOTH connection is made properly, both the 1 indicator (green)
and 

 indicator (blue) light up indicating that pairing is complete, and pairing

information is memorized on this unit.

If you turn off this unit or the BLUETOOTH stereo audio source device before the BLUETOOTH
connection is complete, pairing information is not memorized and pairing will not be completed.
