Notes on batteries

� Use new alkaline batteries. � Do not pair different types of batteries. � 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 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.

Good

The indication may be incorrect if the batteries are not new when installed. If you plan to use the tuner for a long period, it is best to replace the batteries with new ones.
