Using mode button
•Look through the ends of the clear light casing. One end has a red button inside; the other has a
USB receptacle for charging.
•Press button briefly to turn on, or change modes.
•Hold one second to turn off.
Remove end for charging.
•The end cap that covers the USB charging has a bayonet style fitment; twist to release.
•The cap may get water or dirt within the mechansism, but this should not pass the o-ring seal. If
the cap becomes dirty, it can be washed while the unit is on charge.
•Remember to re-seat the o-ring if it comes out during washing.
•If o-ring ever needs replacing, it is a hard-to-find 50-duro part. Spare parts are available at the
NiteFlux website.
Charging
•Power for charging the Red Zone is passed into the USB socket. You can use a USB port on
any computer, iPod charger, 5V car adapter or similar. Anything with a USB socket and 5V,
500mA rating or higher will work. Some 5V chargers (eg Motorolla, Garmin) have the same
USB plug (USB mini) and will also do a good job.
•NiteFlux provides a short (USB mini) cable. Other suitable USB mini cables are widely
available in other lengths. You may have other cables at home or office with USB mini on one
end. There is no special cable properties required. Any USB mini cable will normally work
well.
•During charging, orange LED indicator means charge in progress. Plain green indicates charge
done. It is normal for the orange to blink on again from time to time. This indicates charge is
being topped up or maintained.
•Charge before use. The Red Zone can be recharged at any time. There is no need to wait for
batteries to finish any sort of cycle.
How to I tell what version I have?
•Through the plastic casing, you can see the LED emitters at the end of the circuit board.
oRz600 (previously rz8) has 2 red emitters each end. Rz300 has 1 red emitter each end.
oNew 2022 rz1000 looks externally similar to the old rz8 but has USB-C charge socket.
oOther markings may be added from time to time.

Range of power settings
•The Red Zone has a wide range of power levels as outlined in the table below. The unit is
shipped with settings 1, 5, and 8 active. All the rest are blanked out. You can edit this power
menu at any time and choose your own favorites. Most people will settle for a small number of
active settings, the actual levels that are chosen allows for personal preference. It is
recommended that at least one softer setting be retained for use at night, and one bright flashing
be retained for use during the daytime.
•Skipping a power setting is very easy. Just click the mode button until you get to the setting that
you want to remove. Then hold the button down and the light will turn off. Keep holding the
button down. After 5 seconds continuous hold, the light will come back on and the unwanted
power setting will be gone. The light will come back in the power that is next on the active list.
•NB: while it is very easy to skip a single power setting, skipping several and keeping track of
the power settings that remain is more difficult. It is recommended that you sit in a quiet
location so that you can concentrate. Write out a list with all 8 power settings on. Cross off the
power settings as you deactivate them.
•If you use the 5-second hold to skip the last remaining power setting, the whole list will return
and you can start over again.
•Visit the NiteFlux website for a video that shows how to edit the power menu. Find it on the
Red Zone product page in the instruction manual tab.
•In 2022 there are additional solid-flashing hybrid patterns, making 16 levels in total. This is a
lot but the editing is usually only done once, then day to day use is simple.

Settings lock:
If you have kids around that fiddle with your stuff, or perhaps if you are the manager of a fleet of
cycles and want to set up and keep the settings from being changed, you can use the settings lock
function. When the lock is set, neither the power settings, nor the flashing settings can be changed.
•Start with light turned off, charger unplugged.
•Hold the button down before connecting the charger. Keep hold until the charger is connected.
Release the button once the charger is connected.
oA distinctive fast, repetitive flashing pattern in the orange-green charge light indicates
the lock is set. The flashing will expire after 30 seconds, but the lock is stored in
memory.
•To remove the lock, start with light turned off, unplugged, then repeat as above.
oObserve normal charge light function to verify the lock is removed.
Flashing patterns
•The Red Zone ships with a strident quadruple flashing pattern by default. This is certainly eye
catching but some users will have other preferences. The user can choose from 8 different
flashing patterns, including a range of tame single flash options so there is sure to be one that
suits people that are sensitive to bright flashing lights. NB: not all flash patterns yield the same
runtimes.
•To enter the flash selection menu, first switch the light to flashing mode.
•Turn the light off. Turn on and off again quickly. Just holding your finger on the button for 1
second is the easiest way to do this. Repeat 5 times.
•Now turn on and use normal button clicks to scroll through the 8 different options. When the
light is turned off again, the changes are stored in memory.
•You can repeat the process at any time.
•Visit the NiteFlux website for a video that shows how to edit the flashing pattern menu. Find it
on the Red Zone product page in the instruction manual tab.
•Note the video on our site was produced in 2011 but is still valid. When using the 2022 version
(with runtime indicator after turn-off), be sure to wait for the flashes to stop before turning on
again.
Low Battery Indicator
•When the battery voltage gets lower, the flash pattern will change from the default quadruple
flash (or whatever option the user has selected) to a brief single flash. The power will also
revert to a low setting. The battery should be recharged as soon as convenient. If the light is in
a solid mode, then it will begin to blink and will blink more frequently as the battery voltage
gets lower.
•If the battery voltage gets very low, the light will shut off.
•NB: it is recommended to avoid relying on low battery indicators for cue to recharge. There can
be considerable variation in the length of warning that this basic system gives, depending on the
age of the battery, and the ambient temperature conditions. It is recommended to recharge
regularly and avoid running out of charge while out riding.

NiteFlux Red Zone Manual 2022 Page 5 of 9
Runtime indicator
•1 - 4 soft flashes immediately after turn-on, and after turn-off indicate remaining runtime as a
fraction of full charge
o4 flashes: between full and ¾ full.
o3 flashes: between ¾ and ½ full
o2 flashes: between ½ and ¼ full.
o1 flash: between ¼ full and empty. Recommend recharge when convenient.
•If the battery ever gets to the low battery indicator, the nominal runtime is re-recorded. Thus
the runtime indicator adapts to changed runtime over the life of the product.
•Runtime indicator does not work until first complete charge. Charge before first use.
•Indicator level resets to 4 flashes on full charge, once green charge light is showing for one
second at a time or more.
•Partial/incomplete charge locks indicator to just one flash. Complete recharge to unlock.

Attachments
The Red Zone produces a strong light, across a very wide angle. This simplifies mounting issues as
there is no need to be concerned with precise alignment. Generally, any position that leaves the
light facing approximately rearwards will be effective.
Seat Post:
Attach two Velcro dots to seat post and hook pads to light casing. A simple Velcro strap secures to
the seat post. Use scissors to remove excess strap length so it won’t snag on your pants.
Mount with charger cap upwards and switch downwards.
Saddle Bag and backpack loops:
Saddle bag is a popular location, especially on bikes where the seat post is very short.
When mounted on a back pack, you can carry with you. Saves time removing when you park the
bike in public spaces.
Use a releasable cable tie; through the loop on your bag and around the red zone tube. This system
is simple and very secure. NiteFlux supplies a couple of these releasable ties with the kit but they
are also available at our website or electronics stores.

NiteFlux Red Zone Manual 2022 Page 7 of 9
Helmet
Helmet mounting is a popular way to get the light up high and visible above some surrounding
vehicles in traffic. It is also a popular choice for people that ride many different bikes but wear just
one helmet. It is also a very aero-dynamic position.
Use a releasable cable tie and secure to the occipital strap. Very comfortable and won’t interfere
with the balance of the helmet when wearing, or during crash.
There is no need to remove the light for charging, just remove the end cap and charge in-situ.
Other locations
Because the end cap quickly and easily removes for charging, it is possible to make more
permanent attachment to bags, or other bike parts with non-releasable cable ties or other methods.
So long as the end cap is removable, and your charge cable is long enough, you may recharge the
light in place.
