Under such conditions, it is recommended that you use the meter in the cordless flash mode or Wireless flash radio triggering mode, and keep the Synchro terminal cap in place.
NOTE:
•The electronic flash unit may trigger when you connect the Synchro cord or operate the Power button.
•Triggering voltage is 2.0 to 400 volts. Below 2.0V, trigger flash with the cordless flash mode (see page 22) or wireless flash radio triggering mode (see page 28), not with synchro cord.
