1. Check the Power Source

Only use the provided chargers and cables included with your equipment.

Try a different outlet or power source to confirm the power supply is not causing the issue.

2. Check The Battery And Charger

Be sure the battery is fully charged and is charging correctly.

3. Reinstall firmware

In some cases, firmware can be uploaded to your unit with an error causing odd issues like the screen powering on but using the touch screen to power it on does nothing.

1. Delete any downloaded firmware on your computer
2. restart your computer 
3. redownload the current firmware version and follow firmware installations as instructed.

4. Eject the connected unit before unplugging it.
5. Power on the unit.

4. Charging & Life Expectancy

It is important to use the dedicated charging cord and power supply that is supplied with the unit. Not doing and sending the wrong voltage could cause long-term or permanent damage.
 

FJ80 II

• The average charge time is ~2 hours from complete discharge. 
• The FJ80 Lithium-Polymer Battery will achieve at least 300 full charge cycles (@80% after 300). Continued usage beyond the expected charge cycles will result in diminished performance and the ability to hold a charge. 
• Avoid charging and using the battery outside of the stated operating temperatures (14~122°F / - 10°~50°C) as it will affect the overall performance of the battery and speedlight. 
• Preserve the battery’s longevity by storing at roughly ~40% capacity at room temperature in a dry environment and recharge to this capacity at least once every three months when not being used.

FJ80 SE

• The average charge time is ~3 hours from complete discharge. 
• The FJ80-SE Lithium-ion Battery will achieve at least 200 full-charge cycles (@80% capacity after 200). Usage beyond charge cycles may result in diminished performance and the ability to hold a charge for extended periods. 
• Avoid charging and using the battery outside of the stated operating temperatures (14~131°F / - 10°~55°C) as it will affect the overall performance of the battery and speedlight. 
• Preserve the battery’s longevity by storing at roughly ~40% capacity at room temperature in a dry environment and recharge to this capacity at least once every three months when not being used.

• Avoid charging and using the battery outside of the stated operating temperatures (14~122°F / -10°~50°C) as it will affect the overall performance of the battery and speedlight. 
• Preserve the battery’s longevity by storing at roughly ~75% capacity (3 indicator lights) at room temperature in a dry environment and recharge to this capacity at least every three months when not being used. 

Contact Westcott Support if you find your battery or charger is not operating normally after considering the information above. 
After or near 300 charge cycles or repeated events of charging outside of recommended temperatures or voltages, consider replacing your battery.
