Radio receiver
Your UltraPro has a built-in 2.4GHz radio receiver and we will be introducing an optional radio
transmitter for it soon. The UltraPro radio trigger will allow you to fire all flash heads by radio signal,
without the need to buy a radio receiver for each flash head, and without the need to use the built in
slave cell. This is especially useful if you are involved with event photography and need to turn off the
slave cell to prevent your flash heads from being fired by other flashes, or if you are working in a studio
where other photographers are using flash. The UltraPro can also be used with any normal radio
receiver, simply by plugging the radio receiver into the synch socket (6).
Power dump
Your UltraPro flash head has an automatic power dump, which reduces the power stored in the
capacitors to the correct level when the power setting is reduced. This reduction is achieved by firing the
flash, the advantage of this method is that it does not involve using a resister to dump the power, it is
extremely accurate and precise and does not cause a build up of heat.
The flash tube is user replaceable, which means that you can replace it simply by pulling out the old one
and replacing it with a new one.
But our flash tubes very rarely fail and you are very unlikely to need to replace a flash tube unless it has
been damaged by accident.
The flash tube must never be touched with bare fingers, because grease from skin will substantially
shorten the life of the tube. Grease can be removed with the help of alcohol.
Fuse
The system is protected by a 15A fuse, which can be replaced if necessary by gently levering out the
fuse holder, located immediately above the mains lead socket.
Mains Lead
The UltraPro is supplied with a standard UK mains lead. An alternative EU mains lead is available from
our website, and is listed in the ‘spares’ section.
