User Manual
A multivoltage 100–240 V AC, 50/60 Hz 
charger is included with the Venture TTL 600 
for the rechargeable Li-ion battery.
To charge the battery:
1.  Plug the AC cord into a wall outlet, and 
the charger’s indicator light will glow 
green to indicate that power is being 
received.
2.  Connect the DC cord to the battery. The 
indicator light will glow red to indicate 
the battery is charging, and green to 
indicate that the battery is charged.
To install the battery:
1.  Slide the insertion guides into the slots 
in the battery compartment. Make sure 
the metal contact plates on the battery 
are aligned with the contacts in the 
battery compartment.
2.  Press the battery into place until it 
clicks shut.
Note: Impact recommends fully charging 
the battery before its initial use and after an 
extended period of inactivity (more than two 
months).
 If the unit is left unused for an extended 
period of two weeks or more, or if the unit 
has been used predominately at low-power 
settings, set the power to maximum and 
switch the monolight on (with the modeling 
lamp off) for at least 10 minutes. This will 
help preserve the life of the capacitors.
When not in use, the battery loses 
approximately 3%–14% of its charge per 
month. To maintain your battery, recharge it 
every 2–3 months, even if it’s not in use.
