^ • Even when an external power source Is used, batteries must still be installed In
the IVIR-14EX to power its internal circuitry.
• The MR-14EX uses both the internal and external power sources to recycle
the flash. Therefore, the interrial power source may become exhausted sooner
than the external power source. For prolonged flash photography, keep a spare
set of sIze-AA batteries handy for the internal power source.
