V42 (omni) –Operation Guide
ver.v42.r01.1 jrb2019
v42 Overview
The v42 (omni) has two main LEDs. A focused spot LED and a wide angle flood LED with optic. In normal
operation, the v42 has four factory default power settings. The v42 also has a separate side LED (white smd
LED) for maximum run time, and battery charge level indication visible without removing helmet.
The v42 can be programmed using optional Customduo infrared remote control. From 1-9 light settings can
be specified, and the level of light provided by the spot and/or flood LEDs for each setting can be configured
by the user. The spot and flood LEDs can be operated separately or blended together.
V42 Operation
To switch between the settings, use the down switch on the Petzl Duo. Switch on-off-on-off etc, to
move between settings 1-2-3-4 ... 1-2-3 etc, in a forward looping sequence. Setting 1 will blink momentarily
whenever selected to make it very easy to determine where you are in the sequence, and which setting has
been selected.
The factory default light settings are;
1. low flood - hands and knees caving !
2. high spot - route finding in large passages
3. medium flood - general progression around cave
4. high spot & high flood - if you really must !!
Side LED and Battery Charge Level Indicator
The v42 has a separate side LED (white smd LED) for maximum run time, and battery charge level
indication visible without removing helmet. Operating the switch very quickly, on-off-on ('double
switch') will turn on low power side LED. At this point, the main LED will blink 1 to 5 times to indicate the
approximate level of battery charge. 5 blinks indicates fully charged and 1 blink very flat. The light is visible
underground, on the back of your hand, such that battery condition can be determined without the
inconvenience of removing your helmet. The battery level indicator is set for 4xAA cells (Ni-mh or alkaline).
The side LED will continue to operate until the lamp is next switched off. This low level light is well suited to
underground camp, expedition, small passage caving, long prusiks and emergency.
3 second mode memory
The v42 features a 3 second 'first' mode memory. When lamp has been on for more than 3 seconds in any
setting and is switched off, then it will automatically restart at the first setting when next switched on.
This can be changed to 3 second 'last' mode memory (see module programming below). When lamp has
been on for more than 3 seconds in any setting and is switched off, then it will automatically restart in the
last used setting when next switched on.
Thermal management
The v42 incorporates thermal management in order to protect the module from over temperature
operation. This may be significant if using high output setting for extended time periods. If the module is too
hot, it will automatically step the power down to a lower level of light in order to protect the
LED, and remain at this level until next switch operation (and the side smd LED will blink, but you would need
to remove helmet to see this, so as not to cause irritation to the user).
Lamp function is not locked, and simply changing light setting will restore full operation, though be aware
that unless a lower light setting is used for a few minutes in order to provide time for the module to cool,
then thermal management may quickly reactivate. In reality, you are probably only likely to see this
when running high settings as the v42 uses thermally efficient LEDs and provides a reasonably effective heat
sink.
Programming v42
The v42 can be easily configured to individual requirements, using the Customduo infrared remote control.
To program lamp, point the controller at the v42 module. Petzl Duo front window. The infrared receiver is
on the v42 module. Whenever the remote is operated the smd LED will illuminate to indicate
communication with the v42 module.
Programming is possible when the side LED is switched on (double switch), once the main LEDs have finished
blinking sequence to indicate the level of battery charge. In order to enable programming, the remote must
initially be operated within 30 seconds. This opens a rolling 2 minute programming window, reset whenever
remote is operated. If no programming activity has occurred for 2 minutes (i.e. the remote has not been
used), then the programming window is automatically closed.
Number of light settings
The v42 has 4 factory default light settings. This can be modified from 1 to 9 settings depending on user
requirement. To select the desired number of light settings enter # followed by the number of settings
required and OK to confirm, <#(number of settings 1-9)OK>.
If the number of light settings selected is less than the current number, then any settings no longer required
will be taken from the end of the current sequence. For example, if lamp is currently configured with 6
settings, and 3 settings are selected, settings 4-6 will be removed.
Any additional settings will be added to the end of the current sequence, immediately before the off
position. These will be set at low flood (50mA), unless they have previously been programmed, in which case
they will be set at the last stored configuration.
Configuring a light setting
The v42 allows the light level provided by the spot and/or flood LEDs to be modified for each setting, to
individual requirement.
The spot and flood LEDs can be operated separately or blended together. Each LED can be operated at v.low
(50mA), low (150mA), medium (350mA), and high (700mA), offering a choice from 24 possible light
combinations, as per following table (settings 1-4 are the four factory default levels).

To modify a light setting, enter * followed by the number of the specific setting you wish to modify
<*(setting number 1-9)>. This will only respond to the number of light settings currently specified (as
described above). For example, if the lamp currently has 4 light settings, then only controller buttons 1-4 will
respond.
When a valid light setting is selected, use the arrow buttons on the remote to select the desired level of light
for each LED. The level of the spot LED is set using the <up> and <down> arrows, and the level of the flood
LED is set using the <left> and <right> arrows. Either of the LEDs can be set as off, but not both. When you
have selected the desired light levels of spot and flood LEDs, then enter <OK> to confirm. This procedure can
be repeated for any specified light setting.
The spot and flood LEDs can be operated separately or blended together. Each LED can be operated at v.low
(50mA), low (150mA), medium (350mA), and high (700mA), offering a choice from 24 possible light
combinations, as per following table (settings 1-4 are the four factory default levels).
While using the arrow buttons to select light level of the LEDs, you will note that the flood and spot LEDs
light up at significantly lower levels than during actual lamp operation! These levels are simply
representative of the 4 power settings of each LED, but set at lower level in order to protect your vision
when programming. However, even at these lower levels direct eye exposure should still be avoided.
3 second 'first' mode or 3 second 'last' mode
To switch between 3 second 'first' mode and 3 second 'last' mode, enter <*(0)OK>. Each time this is
performed, the v42 will toggle between 3 second 'first' mode (the spot LED will briefly light up) and 3 second
'last' mode (the flood LED will briefly light up).
Restore factory default settings
If at any point you get in a pickle, then enter <#(0)OK> to restore v42 to factory default settings.
V42 Fitting Guidance
CustomDUO LED upgrade modules will work with all variants of the original pre 2018 Petzl Duo. Modules
are not available for the 2018 DuoZ and DuoS, which are factory sealed and not designed to be upgradeable.
Prior to fitting it is of course necessary to remove original reflector, bulbs, LED modules, etc. Unscrewing the
grey bezel in order to remove the front window can sometimes prove challenging if Duo has been left to rot,
but inevitably they do come off. (Hint, if you can't do it then find someone with strong hands. The trick is to
squeeze and turn at the same time !!!)
CustomDUO Omni modules are a simple push fit into the Petzl Duo lamp housing. Electronic connection is
via the 2 pins on reverse of module which locate in the Duo bi-pin bulb / LED connection socket. Orientate
Omni module in the body of your Duo, aligning the contact pins, and push fit module into place. Ensure the
module is sat down fully in Duo body. Test operation of module. If module does not work immediately, then
read about battery polarity below.
To conclude, refit the Duo front window. Some silicone grease on the seal and threads is always a good idea.
Holding window in position with thumb, refit the grey plastic bezel until the Petzl correct fitting alignment
marks (on top of the lamp) are correctly orientated. The marker formed on the grey screw bezel should be
somewhere in between the two markers formed on the top of the yellow lamp body.
Polarity
Very occasionally we come across an early (pre 2004) Petzl Duo which has been wired up back to front, and
the polarity is wrong for the Customduo LED modules. This affected some, but not all early Duos, and these
Duos are now extremely rare. Polarity conscious LEDs hadn't been considered at this time so it wasn't
important which way around the positive and negative were wired at manufacture. If you fit your
CustomDUO module and it does not immediately work, chances are that your Duo is wired up back to front.
The solution is simple. Reverse the polarity of the batteries in the holder, i.e. positive to negative, and vice
versa. The module will then work. CustomDUO modules are polarity protected, so you will not have
damaged the module by finding this out. If this does not work then please contact us. There is invariably a
solution.
Batteries, power and light output
As standard, the Petzl Duo uses 4xAA batteries (some use 4x C cells). It is important to note that the highest
power settings of the v42 module, i.e. 700mA flood and 700mA spot, 1400mA combined, may not be
achievable dependant on battery type (NiMh or Alkaline), battery quality / condition, and level of charge.
Lamp condition is also a factor. If the batteries cannot deliver e.g. the 1400mA required, the lamp will
operate as normal, but not at full brightness. The slight upside of this is that reduced power draw from
batteries by default will result in extended operating durations.
In our opinion, 1400mA is at the limit of what can be realistically achieved with Petzl Duo and the best AA
cells, given the battery technology currently available. For best result we suggest low self discharge NiMh
batteries, such as the 'Eneloop' brand.
The regulated power settings levels for modules are given in mA. To determine the approximate regulated
duration of light on your battery arrangement at a given power setting, simply divide the mAh capacity of
your cell pack by the mA power draw at a given setting. For example, using 2100mAh NiMh low self
discharge AA batteries at a power setting of 350mA will give a regulated duration in the region of 5-6 hours.
The v42 has zero battery consumption when switched off, so there is no requirement to disconnect
batteries. However it is probably best practice to do so when not in use for more than a few days, to reduce
any stress on battery contacts in Duo box.
High Power LEDs
The v42 uses high power LEDs and is fairly bright. Do not look at LEDs in operation. Eye injury can result. Be
especially careful of this when programming light settings. Do not shine you light into other people’s eyes,
particularly at close range. For more information, see Cree website.
