Power Supply
The unit operates from two AA batteries (alkaline, nickel
metal hydride, or lithium batteries), power supplied from
a supply connected to the USB connector, or power
supplied from the auxiliary connector. The power supply
that has precedence when both AA battery power and an
external power supply via the USB connector or auxiliary
connector are available can be specified using the PWR
SOURCE (external power selection) function. Under the
factory default setting, the power supplied from inserted
AA batteries has precedence. For details about inserting
batteries and displaying the battery level, or supplying
power from supply connected to the USB connector, see
the following sections.
For details on the PWR SOURCE function setting, see
“Selecting the preferred power supply (PWR SOURCE)”
(page 13).
The use of manganese batteries will result in poor
performance. Do not use manganese batteries.
Inserting the Batteries
• Always use sets of the same type of battery. Do not use
batteries of different types or batteries with different
charge level together.
• Replacing the batteries during operation may generate
a large noise. Be sure to turn off the unit before
replacing the batteries.
1 Turn the power off.
2 Slide the two catches inward (as indicated) and pull
the battery compartment out.
3 Insert two new AA batteries into the battery
compartment with 3 and # polarities in the correct
orientation, and close the compartment.
Make sure that the battery compartment is locked
securely.
Battery level indicator
When tuner 1 or tuner 2 is turned on, the unit’s remaining
battery level apears in the display section.
Immediately replace both batteries with new batteries if
the indicator starts flashing (indication 5 below). If using
new alkaline batteries, use after checking the
recommended time limits.
• When BATTERY is set to TYPE1, the battery level is
indicated based on the use of new LR6 (size AA) Sony
alkaline batteries. The battery level may not be
displayed correctly when different kinds of batteries,
different brand of batteries, or old batteries are used. If
using batteries other than size AA alkaline batteries,
select the battery type using the BATTERY function.
• If you plan to use the unit continuously for a long period
of time, it is recommended that you replace the batteries
with brand new ones.
