Notes on Accessories
We recommend using Sony accessories with the unit.
When products from other manufacturers are used,
performance cannot be guaranteed and Sony will not be
liable for any resulting damages.
Notes on the Battery
Charge the battery in an ambient temperature range of
10 °C to 30 °C (50 °F to 86 °F). Efficient charging may not
be possible at other temperatures.
Battery usage
• Battery performance drops in low ambient temperatures,
resulting in shorter usable durations. To extend the usage
duration in low ambient temperatures, place the battery
in your pocket, for example, and insert it in the unit
immediately before use.
• The battery is not waterproof. Be careful not to wet the
battery.
• Do not leave the battery in high temperature
environments, such as inside a hot car or under direct
sunlight.
• If the battery terminals are dirty, problems, such as
power not being supplied or charging not being possible,
may occur. In such cases, wipe the battery terminals with
a dry cloth or cotton swab to remove the dirt.
Battery storage
• Even during extended periods of disuse, charge the
battery about once a year to maintain its functionality.
After charging the battery, insert it in the unit, use it until
it is completely discharged, and then remove it from the
unit before storing it in a cool location with low
humidity.
• To prevent dirtying of the terminals, short circuits, or
other problems, place the removed battery in a plastic
bag, for example, and keep it away from metal objects
during transport or storage.
Battery life cycle
• The battery is a consumable part. The battery’s charge
capacity will gradually decrease as time passes and the
battery is used. When the battery’s usable duration
becomes drastically reduced, it may have reached the
end of its life cycle. Purchase a new battery in such
cases.
• The battery’s life cycle will vary depending on storage
methods, usage conditions, and environments.
Notes on Drip Resistance
The unit is designed with a drip resistance equivalent to
IPX4/IPX5
* . Water entering the inside of the unit may
result in fire, electric shock, or malfunction. Be sure to
read and understand the following precautions before use.
* IPX represents the degree ingress protection against
water. IPX4-equivalent specifications protect unit
functionality against splashes from all directions, while
IPX5-equivalent specifications protect against jets of
water from all directions.
Ensuring drip resistance
Be sure to read the following precautions, and handle the
unit properly.
• The battery compartment cover is plays a vital role in
maintaining drip resistance. When using the unit, be sure
to lock the battery compartment cover securely and
check that it is completely closed. Drip resistance cannot
be maintained when foreign objects are caught between
the cover’s rubber packing and the surface the packing
meets. This may result malfunction due to ingress of
water into the battery compartment. In such cases,
remove the foreign objects with a soft cloth that does not
leave behind particles.
• The unit’s rubber packing may crack or deform over
extended use depending on the usage environment. We
recommend periodic inspections to ensure drip
resistance. For details, contact your Sony representative.
• The unit is not water resistant. Do not submerge the unit
in water, subject it to running faucet water, or otherwise
subject it to high water pressure.
• Drip resistance cannot be guaranteed if the unit is
dropped or otherwise subjected to strong shock. In such
cases, we recommend inspection or repair.
The unit’s drip resistance is based on testing by Sony with
the battery compartment cover completely closed and
locked and the antenna completely secured. Sony will not
be liable for any damages resulting from ingress due to
improper handling of the unit.
