OPENING THE COMPARTMENT

Always turn the strobe to OFF before opening the battery door located at the back of the
strobe.
To access the battery compartment, rotate the knob counter-clockwise several times and
gently pull the door off. Tilt the rear portion of the strobe down while removing
the battery door to eliminate the possibility of water droplets falling into the battery
compartment after a dive. Do not remove the knob from the battery door.
The battery compartment is sealed separately from the main electronics. Do not
disassemble the strobe. Disassembly will void your Ikelite limited warranty.

BATTERY COMPARTMENT O-RING

Be aware of the position of the o-ring around the perimeter of the battery door. Keep the
o-ring and sealing surfaces clean.
Lubricant is not necessary for proper sealing of the battery door o-ring. To extend its life,
you can lightly lubricate the exposed part of the door's o-ring before storing
(see "Cleaning and Storage", page 18).

CHANGING THE BATTERIES

Install four AA-cell batteries: alkaline, NiCad, or NiMH. Refer to the "+" and " – " markings
in the battery compartment to help properly install the batteries. If the batteries are
installed incorrectly, it may damage the strobe's electronics.
Always carry spare batteries; weak batteries cause many camera and strobe problems.
It's time to replace the batteries when the ready light remains dark for 15 seconds or
longer after a flash (see "Strobe Ready Light", page 10).
Note: It is possible to buy bad "new" batteries, so check the voltage output with
a meter. Lithium-ion batteries are not recommended due to their effect on the strobe's
recycle time and the batteries' thermal switch characteristics.
