While High-Voltage Pack E315's main switch is stitt on, do not clean the connector
plllQ with water or a metal pin arld do not tooch the plug.
Even when an external power sourCll is used, batteries must be installed in the 550EX
to power the internal circuitry.
The 550EX uses both the internal and externat power sources to recharge the tlash.
Therefore , the internal power source may become exhausted sooner than the externa l
power source. For prolonged flash photography. keep a spare set of baneries hai1dy
for the internal power source.
