Precautions for use
Common requests
The product is waterproofed, however, do not immerse inside the product in water, and
do not sprinkle water over the attachments and optional items. The micro USB cable is
not waterproofed.
Do not use the product at places where humidity is high, such as in the bathroom, and
avoid rain. Further, when the product is worn, the inside may be corroded due to
humidity caused by sweat, which can cause trouble. Note that in case results of
investigations show that trouble was caused by such water damage, it may be
considered outside the scope of warranty and may not be repaired. Note also that even
when the trouble which is outside the scope of warranty can be repaired, it will be
charged.
Clean the product with soft cloth such as that for eyeglasses. Prints may disappear or
fade in case alcohol, thinner, petroleum ether, soap, etc. are used.
Clean the terminal and plug from time to time with dry cotton swab etc. Uncleaned
terminal and plug may cause bad connection, which could cause insufficient charging.
Therefore, they must be pulled out and cleaned with dry cotton swab. When cleaning
them, make sure that they are not damaged.
DO NOT place the product near the wind outlet of air conditioners. Drastic
temperature change causes condensation, corrodes inside the product and causes
trouble.
Do not pressurize the product.
Putting the product in packed baggage, sitting on it by putting it in a pocket, etc. cause
damage and trouble of the substrates, built-in battery, etc. Further, in case the external
connection device is inserted to the terminal for external connection, pressure causes
damage and trouble.
Please read the handling manual attached to each optional item carefully.

Requests on hitoe Transmitter
Avoid extremely high and low temperatures.
Use the product in the temperature range of 0℃～40℃and in the humidity range of
20％～80％.

The built-in battery is a nondurable.
This depends on how the product is used, however, if the usable time of the product
becomes extremely short even after sufficient charging, it could be the end of the life
of the built-in battery.
Charging must be done at places with appropriate ambient temperatures (10℃～35℃).
Usable time of the built-in battery varies depending on the usage environment and
degree of deterioration of the built-in battery.
When storing the product, the following should be avoided because they degrade the
performance of the built-in battery and shorten its life.
• Storing the product when the battery is fully charged (i.e., right after the completion
of charging)
• Storing the product with no remaining battery (i.e., the battery has been consumed
to the extent that its power cannot be turned on)
Approximate amount of remaining battery suitable for storage is when the state
display lamp is lit in orange.
Requests on hitoe Transmitter
Charging must be done at places with appropriate ambient temperatures (10℃～35℃).
Do not charge at the following places:
• Places where there is a lot of humidity, dust and vibrations.
• Near fixed-line phones, TVs and radios
While charging, the product may become warm, but it is not abnormal and can be used
as it is.

trouble.

Requests in case Bluetooth ®functions are used
As for security during communications using Bluetooth, the product supports the security
functions compliant with the Bluetooth standard specification. However, depending on the
setting, security may not be sufficient. Therefore, caution must be exercised when
communicating by using the Bluetooth functions.
Note that XX is not responsible for data and information leakage during communications
using the Bluetooth functions.
The following is the frequency band used by the Bluetooth functions of the product.
2.4 ：Indicates that the radio facility uses the 2400MHz band
XX ：Indicates that the modulation scheme is other schemes.
1：Indicates that assumed interfering distance is 10 m or less.
: Means that the entire band of 2400MHz～2483.5MHz is used and that the
bands for mobile system identification devices cannot be avoided.
Check with airline companies before using the product during a flight.
Precautions for use of Bluetooth devices: In the frequency band in which the product is
operated, in addition to electric household devices such as microwave ovens and
industrial, scientific, and medical equipment, licensed premises radio stations for mobile
system identification devices used in production lines of factories, unlicensed special low
power radio stations, amateur radio stations etc. (hereafter called ‘other radio stations’)
are operated.
1. Before using the product, confirm that ’other radio stations’ are not operated nearby.
2. Should there be interference between the product and ’other radio stations’, immediately
avoid it by changing the place of used or by ‘turn off the power’.
3. If you have any questions, please contact the ’Inquires’ indicated at the back of the
handling manual.
The product and all the devices with Bluetooth functions have been confirmed that they
are compliant with the Bluetooth standard specification by employing the methods
specified by Bluetooth SIG and have been certified. However, depending on the

Caution
Never use the altered product. Use of altered devices infringes the radio law. The product
abides by the rules concerning the technical standards conformity certification etc. of
specified radio equipment based on the radio law. As a proof, the ’technical standards
conformity certification mark’ is displayed on the name sticker on the product. If inside the
product is altered by unscrewing the screws, the technical standards conformity
certification etc. will become invalid. Use of the product with invalidated technical
standards conformity certification infringes the radio law, so we strong request never to
use it.

product is compliant with Japanese and American radio specifications only and have been
certified accordingly. Users may be punished for using this product overseas elsewhere.

The product has the IPX5※1 and IPX7※2waterproof performance when the cover of the
terminal for external connection is tightly closed without openings or gaps.
※1.IPX5 means that functions are protected from water jets created with a water nozzle of
the inside diameter of 6.3mm with 12.5L/min. of water coming from the distance of approx.
3m for at least 3 minutes from any direction.
※2.IPX7 means that functions are protected when products are dropped in 1 m-deep
normal temperature, tap and still water gently and picked up in approx. 30 min.
(Note) They do not guarantee all the operations in all the conditions. Therefore, in order to
prevent entering of water and foreign substances, and use the product safely, read the
manual carefully before use.
■Important items to check before use
Tightly close the cover for the terminal for external connection before use. Even a small
gap made by small objects (e.g. thin fiber, hair, sand, etc.) could cause water and dust to
enter the product.
When closing the cover for the terminal for external connection, check that dust and dirt
are not clinging to the area around the cover (especially to the packing).
Check that the cover for the terminal for external connection is tightly closed without
openings or gaps. If it is not tightly closed, water may enter.
■Precautions
Do not wash in a washing machine or supersonic washing machine.
Never charge when the product is wet.
Do not leave the product with drops of water on the product.
Do not drop or inflict an impact on the product.
Do not dip the product in hot water, use it in a sauna or blow a hair dryer’s hot air on it.
