Battery indication
When you turn the power on, the battery status of this unit

Note
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.
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.
