Operation Manual

Caring for Flash Trigger
Avoid sudden drops. The device may fail to work after strong shocks, impacts, or
excess stress.
Keep dry. The product isn't water-proof. Malfunction, rust, and corrosion may occur and
go beyond repair if soaked in water or exposed to high humidity.
Avoid sudden temperature changes. Condensation happens if sudden temperature
changes such as the circumstance when taking the transceiver out of a building with
higher temperature to outside in winter. Please put the transceiver in a handbag or
plastic bag beforehand.
Keep away from strong magnetic field. The strong static or magnetic field produced
by devices such as radio transmitters leads to malfunction.
