• Always use the IPS charger supplied with the device (or purchased separately) to charge IPS batteries. Using an unsuitable charger can cause irreparable damage to the battery and fire.
• Do not charge the battery immediately after bringing it from cold to warm. Wait at least 30 minutes for the battery to warm up.
• Do not leave the battery unattended while charging.
• Do not use the charger if it has been modified or damaged.
• Do not leave the battery in a charger connected to the network after charging is complete.
• Do not expose the battery to high temperatures and naked flame.
• Do not use the battery as a power source for devices that do not support IPS7 batteries.
• Do not disassemble or deform the battery.
• Do not drop or strike the battery.
• Do not submerge the battery.
• Keep the battery out of the reach of children.

Attention! Please do not use the IPS 14 Battery Pack with the Krypton FXG50 due to the battery´s heavy weight.

• The battery should be partially charged for long-term storage – 50 to 80 %.
• The battery should be charged at an ambient temperature of 0°C…+35°C (+32°F…+95°F). Otherwise, lifespan of the battery will decrease significantly.
• When using the battery at sub-zero temperatures, the battery capacity decreases, this is normal and not a defect.
• Do not use the battery at temperatures outside the range of -25 °С…+50 °С (-13°F…+122°F) – this may reduce battery’s life.
• The battery has a short-circuit protection. However, any situation that may cause short-circuiting should be avoided.

The device is supplied with a rechargeable IPS7 Lithium-ion Battery Pack which allows the attachment to be used for up to 8 hours. Charge the battery before first use.

Charging

Step 1. Install the battery into the charger

1. Raise the lever (4) of the charger.
2. Install the Battery Pack (5) into the charger.
3. Click the lever (4).

Step 2. Сheck the current battery level

• Upon installation, a green LED indicator on the charger will start to glow and begin flashing:

– once if the battery charge ranges from 0% to 50%.

– twice if the battery charge ranges from 51% to 75%.

– three times if the battery charge ranges from 76% to 100%.

• When the indicator is continuously green, the battery is fully charged. Disconnect the charger from the mains and disconnect the battery from the charger.
• If the battery charger indicator is constantly red when the battery is inserted, the charge level is probably below the permissible level (the battery has been in a discharged state for a long period of time). Leave the battery in the charger for a long period of time (up to several hours), then remove and reinsert.
• If the indicator begins to flash green, the battery is good.
• If it continues to show red, the battery is defective. Do not use this battery!

The LED indicator will display the battery charge status:

LED Indicator	Battery Charge Status
	Battery is empty
	Battery is full
