2.
Plug-in external or built-in PocketWizard receivers are required to work with the
PocketWizard wireless technology.
Once the transmitter module is installed in your L-858D, you will be able to adjust the
power level and trigger ashes to get the look you desire. For more information about the
meter, refer to the L-858D Operating Manual.
For more information about PocketWizard, go to www.pocketwizard.com.
About PocketWizard Wireless Technology

<Standard System>
PocketWizard Standard system provides simple triggering and do not allow power
control. The Standard system features 32 channels: Channels 1-16 re single trigger
signals; Channels 17-32 have four zones (A, B, C, D) which enable triggering four
separate ashes on each channel.
<ControlTL System>
When used with ControlTL receivers, the L-858D is capable of controlling the power
level of the compatible ashes connected.
The ControlTL system features 20 channels for FCC&IC version or 3 channels for
CE version, and three zones (A, B, C) allowing control of three separate ashes on
each channel.
<Radio Frequency>
To comply with local broadcast regulations, Sekonic wireless systems sold in the
various markets around the world are designed to operate at different frequencies.
Sekonic meters have built-in transmitting antennas that are specically tuned for
their market area. When purchasing and/or installing a transmitter module or using
the meter with a receiver, be sure that the meter and receiver are designed to be
used in your location and use the same frequency.
How to use L-858D with PocketWizard
Wireless Technology
●
USA/North American market frequencies (FCC & Canada IC): 344.0 to 354.0MHz
●
European and other market frequencies (CE, NCC or OFCA): 433.42 to
434.42MHz
2
2. About PocketWizard Wireless Technology ●
NOTICE
Successful radio triggering depends on several factors. Please read these setup steps
before using the L-858D to radio trigger ash units.
1. It is the best to position the meter in sight of the radio receiver (or ash head).
2. Position the radio receiver so that it is away from large metallic objects, concrete, or
containers of water (like people).
3. Secure the radio receiver to the ash using hook-and-loop-type attachment tape or
the threaded socket on the radio. Make sure the radio’s antenna is above the ash
body or generator pack. Do not allow the receiver antenna to contact metal objects.
4. Sometimes, conditions do not allow radio reception. These could include strong
local radio interference or being near objects that block or absorb the signal.
Repositioning the radio, even slightly, can reestablish contact. Alternatively, check to
see if the radio receiver is behind objects that absorb or block radio waves, such as
concrete, metal or low hill.
5. Operation is the best when the meter to receiver distance is within 30 meters.

Two rules apply to the reference ash duration
time.
t0.5 = Effective ash duration time
t0.1 = Total ash duration time
After ash ring, the time at which the
maximum intensity drops by half is called “t0.5”.
The time at which the maximum intensity drops
to 1/10 is called “t0.1”.
Generally, “t0.5” is called the ash duration
time.

Troubleshooting
If your meter is not operating properly, as you expect, please consult the following
conditions and attempt the suggested solutions before contacting Sekonic. Nonoperation can be due to incorrect, mis-setting of the meter or battery condition.
Should your meter be malfunctioning, please contact place where meter was
purchased or Sekonic for service and repair.
Condition Possible reasons What to do
Flash cannot be
triggered in Radio
Triggering Flash
Mode.
Is the radio receiver in the
ash compatible with the
meter’s transmitter? Isn’t any
other non-compatible brand or
manufacturer used?
Are the meter transmitter and
receivers set for the same
channel number?
Are the meter and receiver set
for the same ControlTL and/or
Standard channel and zones?
Are the meter transmitter
and receiver set for the same
frequency?
Make sure that both the meter
and plug-in external or built-in
PocketWizard receivers to the same
system (Standard and/or ControlTL).
http://www.pocketwizard.com/
Set the same channel number and
zones on the transmitter and the
receivers.
Check that the transmitter and
receiver are both set to the same
system (either the standard system
or ControlTL system).
As there are two types of frequency
(344 MHz band and 433 MHz
band), ensure that the transmitter
and frequency have the same
specications.
