Using 600EX-rt aboard
« on: May 28, 2013, 12:22:28 PM »
I just a got a pair of 600EX-Rt from Canon Refurb.  Looking at the insert, it seems that using the flash remotely is not legal in a number of countries.  I imagine this is due to the frequency of that the flash uses communicate.

Is this warning "real" or just CYA for Canon?

The purpose of this, is only to inform you, that, in some countries, it’s illegal to use those frequencies. CYA

it is CYA.
Like the Chinese radio trigger makers which effectively forced  Canon into offering some degree of radio remote flash control the Canon EX-RT system uses the 2.4 GHz band which is basically free to use almost anywhere in the civilized world.
http://www.learn.usa.canon.com/resources/articles/2012/speedlite_600exrt_radio_basics.shtml

---
Radio Transmission:
IEEE 802.15.4, ARIB STD-T66
Primary modulation: OQPSK
Secondary modulation: DS-SS
Sending frequency (center): 2405 to 2475 MHz
---

Pocketwizard chose different frequency bands between 315 MHz and 434 MHz and ran into a lot of regulatory issues.  Effectively they make 3 product variations for different parts of the world, which are mutually non-compatible and which may not be allowed to operate in other countries.
see http://www.pocketwizard.com/inspirations/technology/frequency/

-----
North & South America and parts of Asia = 340.00 to 354.00 MHz FCC/US
Europe, India, China, and other countries = 433.62 - 434.22 MHz CE
Japan = 315.50 - 317.00 MHz

IMPORTANT, PLEASE READ:
PocketWizard radio devices operating on one frequency can not operate with PocketWizard devices on a different radio frequency.  Retailers can not ship devices to markets that use a different frequency and we can not provide proper warranty service for products shipped out of their intended market.

Thought that this was a silly thing to put in the documentation - but I guess some lawyer said you had to just in case someone ever gets in trouble.  At least that warned you ..

So did I but I'm not too crazy about the idea of purchasing another one for that price.
