Notes on batteries
•
Use new alkaline batteries.
•
Do not use different types of batteries together.
•
Always replace the four batteries together.
•
The batteries are not rechargeable.
•
Be careful to install the batteries with the correct polarity.
•
When not using the tuner 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.

connect the DC 12V IN connector to the DC OUT connector
of a camcorder using the power cable supplied. When the
external power is supplied, the tuner functions regardless of
the built-in batteries.
