Solution:

• When using the flash, be careful not to cover it with your fingers or clothing. This could result in burns or damage to the flash.
• In regular use, small amounts of smoke may be emitted from the flash. This is due to the high intensity of the flash burning dust and foreign materials stuck to the front of the unit. Please use a cotton swab to remove dirt, dust or other foreign matter from the flash to prevent heat build-up and damage to the unit.
