Usage and Maintenance of the TK22 Flashlight

• Disassembling the sealed head can cause damage to the light and will void the warranty.

• If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
• Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation. Recharge a stored battery every four months to maintain optimal battery performance.
• When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, the flashlight blinks three times every five minutes to remind you to replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery runs out completely.
