Display lifetime  
Optimus Maximus OLED screen have 20,000 hours of lifetime for average  
brightness level (default setting). After that the brightness might decrease  
with displays still reliable for a significant amount of time. If a screen con-  
tinually displays one and the same image (i.e. only a part of OLED is active)  
its outlines may appear on the display as dark shades.  
 
Safety and maintenance  
Disregard of the safety precautions and improper operation can result in bre-  
aking the keyboard or injuries to users and other people. Study the following  
safety rules carefully before use.

Avoid contact with liquids; do not use  
the keyboard in high humidity (e.g. bath-  
room) as it creates risk of fire or elec-  
tric shock.  
Do not touch power source with wet  
hands.  
Do not expose the keyboard to direct  
sunlight or heat to avoid damage and  
fire.  
Do not insert any foreign objects into  
the equipment. Any intrusion of metal  
or flammable objects creates risk of fire  
or electric shock.  
Wipe the keyboard regularly with  
a piece of cloth. Built-up of dust and  
filth on the equipment, especially in case  
of permanent operation, may cause  
overheating and inflammation.  
Do not disassemble and reassemble  
the keyboard as it may cause fire  
or electric shock. Contact the sellers  
or the producer if repair is needed.  
Unplug the power cord when not in use  
for long.  
Do not interfere with the power cord  
as it creates risk of fire or electric  
shock. Never attempt to repair the cord  
on your own. Do not stretch the cord.  
Do not put heavy objects on the cord.  
Contact the sellers or the producer  
if repair is needed.  
Make sure the keyboard is placed secu-  
rely. Choose stable surface for placing  
to prevent falls and damage.  
Use of a keyboard may cause carpal  
tunnel syndrome and other conditions.  
the factors leading to musculoskeletal  
disorders include the amount of time

to individual medical contra-indications.  
If you experience symptoms such  
as persistent or recurring discomfort,  
do not ignore these warning signs  
and promptly see a qualified health  
professional.

Troubleshooting  
Important! If any of the displays is defective or inadequately installed, you  
will not be able to turn on the keyboard.  
If the following recommendations do not help you to solve the trouble  
you are experiencing contact the producer at support@artlebedev.com.  
You will be offered qualified assistance.  
The keyboard is USB connected, but doesn’t work  
Check if you have plugged in the power cord. If it is plugged in, make sure  
it is plugged in tightly.  
The keyboard doesn’t work after the keys were replaced  
If any of the key displays is defective or inadequately installed, you will not  
be able to turn on the keyboard. Try taking out the newly installed keys one  
by one in reverse order. Perform this with the keyboard turned off, you do not  
need to unplug the USB cable. Upon taking each key out turn on the keyboard  
to check if it works. If you were able to turn it on, it is likely that the key you  
took out last was either defective or inadequately installed.  
The images have become faded. I can see outlines of the previous  
images on light backgrounds  
If the keyboard or a single display were in operation with average brightness  
level for 20,000 hours they might need replacing. They are still reliable, but  
the brightness is permanently lost.  
I have trouble with one-and-a-half/double keys/space bar  
If you have removed them before that, it is likely that they are inadequately  
installed. Consult the instruction at optimus.artlebedev.com. Pay attention  
to explanations concerning the keys in question.  
There is noise when I press one-and-a-half/double keys/space bar  
When installing these keys make sure to have enough grease on the pin. Read  
the instruction at optimus.artlebedev.com and follow the recommendations.  
 
There are greasy spots under the key caps  
If you took out the keys, you could stain them with silicone grease. You can  
try to clean it off by rubbing the surface with weak alcohol. Be very careful  
doing this—do not let the alcohol on the inner electronic side of the key. Be-  
fore putting the key in let the liquid dry a few minutes.  
There are significant image distortions on the key display  
The key or the keyboard may be defective.  
Try placing an efficient key instead of that one. If the distortions remain,  
it is likely that the keyboard is defective.  
If the distortions remain when you install that key into other places, it is  
likely that that key is defective. It needs to be replaced by another one.  
I can’t remove the keys  
You need to apply some effort to remove the keys using the special tool en-  
closed with the keyboard. Before doing this study the instruction at  
optimus.artlebedev.com  
I have bent a pin contact when installing a key  
Before installing keys study the instruction at optimus.artlebedev.com. It also  
contains recommendations on your problem.  
Brightness auto adjustment fails  
This mode is program activated. If it is activated but fails, it is likely that  
there is dust built-up on the light sensor in the right upper corner near  
the logo. Clean it.  
The keyboard doesn’t work after I changed firmware  
You can always go back to the first version. Read how to do this at  
optimus.artlebedev.com.  
The keyboard fell and no longer works  
The keyboard can withstand light shocks, but the key displays are likely  
to get damaged if it falls.  
 
One or several keys could have been damaged which is why you can not  
turn on the keyboard. Try removing the keys one by one checking each time  
whether the keyboard works. the damaged keys need replacing.  
I spilt coffee/tea/water/alcohol/etc. on the keyboard  
Quickly turn off the keyboard, remove all the keys or at least the keys from  
the wet part. Carefully dry the keyboard and do not turn it on for a few days  
as it may cause damage if there is still liquid left inside.  
When the keyboard is completely dry turn it on with several keys. If it works,  
install more keys having turned it off to do so. Keep installing the keys by parts  
up to the last one. Even if the keyboard works, the pressing of the keys may  
be impaired.
