Notes on batteries
• Use new alkaline batteries.
• Do not pair different types of battery.
• Always replace the two batteries together.
• The batteries are not rechargeable.
• Be careful to install the batteries with the correct
polarity.
• When not using the transmitter for a long period,
remove the batteries to avoid leakage. If the
batteries do leak, clean all leakage from the battery
holder case and the unit. Leakage left in the holder
case and the unit may cause poor battery contact. If
there seems to be poor battery contact, consult your
Sony dealer.

Notes
• The transmitter cannot transmit in Setting mode.
• Make sure that the channel selected on the
transmitter is the same as that selected on the tuner
being used in the same system.
• Depending on the noise or interference conditions,
all selectable channels may not be usable. If
necessary, you can determine which channels are
usable by cycling the channel selection through a
number of channels on the tuner with the unit set to
OFF. Those channels for which the RF indicator on
the tuner does not light are usable.
• If there is a TV broadcasting station near by, do not
use the station’s channel.
• The transmitter may not operate correctly if it is
turned on immediately after being turned off in
Setting mode. Wait for a few seconds before turning
the power on again.
• The channel numbers and frequencies of your
transmitter are shown on the “Sony Wireless
Microphone System Frequency List” supplied with
the manual.
