■ When unplugging the power plug, hold the plug. Do not pull it by the cord. Also do not bend or pull the cord
excessively or place a heavy object on it. Damage to the cord may result in fire ignition, overheating and/or
electric shock.
■ Unplug the power plug from the power outlet except when recharging the battery.
At time of purchase:
● The battery discharges even when it is not used. After purchasing the battery, be sure to charge it before use. Also,
whenever the battery has not been used for a long period, recharge it before use.
● New batteries or batteries that have not been used for a long time (more than one month) may not be fully charged. This
is not a malfunction, but is a characteristic of the battery. Charge them two or three times before using them for the
first time or when they have not been used for a long period.
● Check that the battery terminals are clean before use. If they are dirty, contact failure may cause problems with charging
or shorten the battery's operation time after charging.
Care:
● Clean the battery by wiping it with a soft, dry cloth. Never use a wet cloth, alcohol, lacquer thinner, benzene or detergent.
Operating temperatures:
● Use this battery pack within a temperature range of –10°C and +60°C (14°F and 140°F).
● Even within the specified operating temperature range, battery operation time decreases as the temperature drops.
When the temperature is low, it is recommended to carry a spare charged battery and keep it warm in a pocket, bag, etc.
When carrying a battery in your pocket, be sure to cap the battery to prevent short-circuiting. Do not put anything else in
the pocket with the battery.
Precautions for transport and storage:
● Do not leave the battery in the HV-1 High Voltage Pack. Even when the power switch is set to off, a small amount of
current continues to flow and may lead to a decrease in battery performance. When not using the battery, attach the
provided cap and store it in a cool, dry place with a temperature between 15°C and 25°C (39°F and 77°F).
● When transporting or storing the battery, attach the provided cap to prevent short-circuiting of the +/– terminals. Do not
put any metallic objects including personal ornaments in a bag or drawer with the battery. This could cause a fire,
overheating, explosion or leakage.
Service life of rechargeable battery pack:
● The performance of the battery degrades gradually after repeated charge and discharge. When the operation time
reduces considerably, this may be the sign of replacement timing. The battery capacity is usually halved after about 500
cycles of charging and discharging, though this value is variable depending on the operating conditions.
Recycling the battery:
● Please recycle BN-1 batteries to help save our planet's resources. When you throw away dead batteries, be sure to
cover their + and – terminals and always observe local laws and regulations.
Before use:
● Be sure to read the safety precautions thoroughly before use. Follow all instructions carefully.
Operating precautions:
● The optimum ambient temperature for charging is between 10°C and 30°C (50°F and 86°F).
● The battery may get hot, for example immediately after the flash is used. The battery may not fully recharge if it is hot, so
wait until the battery cools down before recharging it.
● The battery charger and battery get hot during charging. This is not a malfunction.
● Interference with TV or radio reception may occur during charging. This is not a malfunction. To avoid this, move the
charger further away from the device being interfered with.
● Even within the specified operating temperature range, battery operation time decreases as the temperature drops.
When the temperature is low, it is recommended to carry a spare charged battery and keep it warm in a pocket, bag, etc.
When carrying a battery in your pocket, be sure to cap the battery to prevent short-circuiting. Do not put anything else in
the pocket with the battery.
Care:
● Clean the battery by wiping it with a soft, dry cloth. Never use a wet cloth, alcohol, lacquer thinner, benzene or detergent.
Overseas use:
● If you plan to use this product in another country, you may need to obtain a conversion plug matching the design of
power outlets used in that country. Check with a travel agent to determine whether or not you will need a converter. Do
not use an electronic transformer as this will cause a malfunction.
