5. Measurement
Reference:
•Refer to the radio Receiver or Transceiver instruction manual for the recommended operating method.
•Maximum distance of the radio flash triggering system can vary depending on the placement of the remote Receiver or Transceiver, direction of the radios antenna, distance from a large body of water or concrete wall and other possible factors.
1.Confirm the range between the meter (transmitter) and Receiver or Transceiver.
2.Place the meter and Receiver or Transceiver away from large metal objects, concrete, objects, large moisture content (both people and trees fall into the category) and so forth.
3.Secure the radio Receiver or Transceiver in place by using Velcro tape or a
4.Depending on the location, there may be cases when the Receiver or Transceiver is incapable of receiving any radio signals whatsoever. There are several possible causes for this such as radio signals reflected off of nearby objects. This can generally be resolved by shifting the meter (Transmitter) or the Receiver or Transceiver slightly in one direction or another. In addition, confirm that the Receiver or Transceiver is not placed behind objects that readily absorb or deflect radio signals such concrete, metal, low hills, etc.
NOTE:
•The Wireless flash triggering system may be used only in countries where a permit for the control frequency has been issued by the government office in charge. There are several kinds of frequencies in the world, and we recommend you check if your transmitter(s) and receiver(s) or Transcevers are compatible with each other.
