Here is how to establish the wireless connectivity on the Drevo Calibur keyboards:

Turn on the Bluetooth of the device to which the keyboard is to be connected.
Press the Fn and Q key combination till the white light starts blinking rapidly.
Tap/Click on the Scan button on the target device.
The keyboard will appear in the list of the visible devices.
Select the keyboard and pair it.
When prompted, type the code on the keyboard that would be shown on the target device.
Follow the procedure to complete the bonding and start using the keyboard wirelessly.
If you want to connect another device then the main procedure will remain the same but you would need to turn off the Bluetooth on the already connected device. As Q key is already used, take W key and repeat the above process. Use the E key for the third device. Once, all the devices are paired, you can turn on the Bluetooth on all the devices. To switch between the connected devices, simply press the Fn and corresponding allotted key from Q, W, and E keys. 
 

You can connect Calibur to your PS4 via USB cable, just for typing not for playing games. The Bluetooth connection is unsupported. 

Yes, you can use the keyboard with a number pad.

For Calibur, Joyeuse, Excalibur, the cable is removable.

For other keyboards, the cable is not removable.

DREVO BladeMaster Series keyboards are compatible with Mac. While, other keyboards are not fully compatible with Mac. If you use USB connection, you can edit prefs keys, or use software like karabiner to program the keys. There is no an official software at present.

For Calibur and Tyrfing, you can use normal standard keycaps to replace the original keycaps, ie https://www.amazon.com/DREVO-104-key-Standard-Mechanical-keyboard/dp/B077M3LDJ8/

For DREVO 84-key keyboards, there are some special keys can not be replaced by standard keycaps - like Backspace, Shift, Spacebar and Enter key.

The light and function of the four key F12, PS, PAU and capslock on DREVO Gramr work as the following.

When the light is on, it indicates the key's function is disabled.

When the light is off, the key's function is enabled.

It's the default setting.

No, the mechanical keyboards have lots of tiny electronic components. Please keep the keyboard away from liquid.

Yes. Before that, please make sure that your phone USB cable is Micro USB and ensure the quality of it.

No, you can't use the Bluetooth when the keyboard is connected by USB cable, obviously that the Bluetooth key doesn't flash at all.

Well, it lacks the physical keys of F1, F2, F3 etc. But you can press FN+1, FN+2 to get these keys.

The keycaps are manufactured in standard specifications, and can support the replacement of most DIY keycaps. The switch is not pluggable.

At present, this keyboard doesn't support to display details of battery status. When the battery runs out, the space bar will turn to red and begin to flash slowly.

(In addition, when you connect the keyboard with your computer through USB cable, the keyboard will be charging automatically, and its space bar will turn to green and begin to flash slowly; If the space bar has no flash in the USB connection mode, that means the keyboard has full charge.

There are seven colors currently. You can custom the light color of each key. When the keyboard driver is released, you could customize every key's light with up to 16.8 million colors.

Dust cleaning under keycaps

Tools: Keycaps remover( included in the package), q-tips or any thin stick with rag tied.

Remove keycaps first, then use the q-tips to gently brush the gap between keys until no obvious litter left. Use clean water to wash keycaps.

Cleaning sticky switches

Tools: Soda water, Straw

Suck in some water, press into switch, then press key repeatedly. Wait till tomorrow.

Liquid spilling reparation

Unplug the USB connector immediately! Turn your keyboard vertically for liquid to drop down, then you should use dry rag to wipe off the remain liquid. Wait until you make sure the keyboard is totally dry.

You can press FN+F12 (Gramr or Excalibur) and press FN+Windows key (Calibur and Tyrfing) to lock or unlock windows key.

At first, you could try to use it in another computer to confirm that if the keyboard is defective; and then you could check out the driver, for example a new installed driver may cause the problem. If this can not help you to solve the problem, don't hesitate to contact us, offer us more details of the problem, and we will help to solve the problem.

For Tyrfing, it is to show the Caps Lock key is triggered;

For Gramr and Excalibur, the F12 (Lock windows), PrintScreen (NumLk), Pause (ScrLk).

Yes. You should confirm the Bluetooth 4.0 adapter quality before doing that.  

We suggest that you could turn off the keyboard before the power off of pc, in order to avoid losing connection with pc.

Because these keys also represent some keys Capslock, WindowsLock, NumLk and ScrLk. When they're not lighted=active, lighted=inactive.

Please check which mode the Knob is in by long pressing FN. In Knob function area(Insert, Home, PageUp, Delete, End, PageDown), the red breathing light indicates the Knob function. The PageDown represents the Knob custom function. If the PageDown key’s light is not red breathing, please press FN+PageDown to trigger the function.

First, please check which onboard memory scheme the keyboard is in by long pressing FN. In the onboard memory schemes, F1,F2,F3 respectively represents G1,G2,G3. The red breathing light indicates which scheme the keyboard is in. G1 can store all lighting effects and key configurations. G2 and G3 can only store one static light effect and key configuration. If the keyboard scheme is in G2/G3, please press FN+Control+F1 to switch the scheme to G1.

It’s because the static overlay effect is turned on in DPC Radi-RGB setting. The front light effect is covered with a layer of static effect. Please turn off the overlay effect in the software.

The current onboard memory scheme only supports configuration of default layer. The configurations of the two extra layers can be achieved with the DPC open.

Please check if the DIP switch is turned on.(The DIP switch is at the back of the keyboard.) Any of the four DIP switches being on will change the keyboard key press setting. For detailed DIP switch setting, please refer to the user manual.

For the basic information of SSD, you can refer to the product page.

Before you can use your new SSD you have to initialize and partition it. Follow the below process, unless you are performing a clean installation of your operating system, or cloning to your SSD, both of which normally do this for you. Note: if you simply need to format/reformat a drive, the following steps below will be needed, assuming your SSD has previously been initialized.

1. Attach the SSD as a secondary drive and load Windows from your existing drive;
2. In Windows 7 and earlier, open 'Disk Management' by right clicking on 'Computer' and selecting 'Manage', then 'Disk Management'. In Windows 8 and later, right-click on the Start Icon, then select Disk Management.
3. When Disk Management opens, a pop-up should appear and prompt you to initialize the SSD.
4. Select MBR (Master Boot Record) and click OK.
5. Right click in the area that says Unallocated and select New Simple Volume...
6. The New Simple Volume Wizard will open, click Next.
7. Leave the Specify Volume Size as the maximum (default value) and click Next.
8. Select a Drive Letter and click Next.
9. In the Format Partition screen, decide on a Volume label (the name you want to give the drive) and click Next.
10. The drive is now formatted and ready for use.

1. Remove and reinstall the SSD, and double check all the connections, including data cable, SATA power cable and SATA port.
2. If it doesn’t work, please try with different SATA data cables, different power cables and different SATA ports.
3. If it doesn’t work still, please try it with a SATA-to-USB cable or drive enclosure externally.
4. If that doesn’t work, reinstall the old drive (Make sure the old drive still works) and checking all connections. If the old drive still works, but the new SSD does not, please contact DREVO Tech Support via Email support@drevo.net or Fackbook @drevo.net, and we will give you a 100% satisfied reply.

If your laptop has a 2.5-inch hard drive, you can use the X1, X1 pro, Zeus, ES SSD in your laptop. If not, you can also use the SSD as an external hard drive through a SATA-to-USB cable or external hard disk enclosure. 

As long as your motherboard has a SATA3 or SATA2 interface, you can use the SSD. For SATA2 interface, the write/read speed is limited within 300MB/S.

Yes, please visit https://www.drevo.net/page/software to download the software and the user guide.

Those of you that are familiar with flash memory products will know that the read and write speed are not only depending on the flash chip, but also be affected by external factors such as operating system, motherboard, CPU, user environment, interfaces (SATA1/2/3, USB2.0/3.0), data cable quality and test software (CrystalDiskMark is preferred) etc. All our test data is just for reference. Therefore, the resulting speed is not due to the quality of the product.

And we recommend that you try using a different SATA cable or plugging the SSD in to a different SATA3 port. This helps to check and see if it’s possibly the connection that is causing the performance to be lower than expected. We would also recommend that you change the SATA mode in your BIOS to AHCI for the best performance.

Hard drive and NAND Flash manufacturers marks drives in terms of decimal (base 10) capacity. In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes; One gigabyte (GB) is equal to 1,000,000,000 bytes. Programs such as FDISK, system BIOS, Windows, and MacOS use the binary (base 2) numbering system. In the binary numbering system, computers count 1,024 bytes per Kilobyte, 1,024 KB per Megabyte, and 1,024 MB per Gigabyte. One megabyte is equal to 1,048,576 bytes; One gigabyte is equal to 1,073,741,824 bytes.

Thus,

60,000,000,000 /1,073,741,824 ≈ 55.90 gigabytes (GB)

64,000,000,000 /1,073,741,824 ≈ 59.60 gigabytes (GB)

120,000,000,000 /1,073,741,824 ≈ 111.79 gigabytes (GB)

128,000,000,000 /1,073,741,824 ≈ 119.24 gigabytes (GB)

240,000,000,000 /1,073,741,824 ≈ 223.57 gigabytes (GB)

256,000,000,000 /1,073,741,824 ≈ 238.47 gigabytes (GB)

480,000,000,000 /1,073,741,824 ≈ 447.03 gigabytes (GB)

Before installing OS, we firstly need to enter BIOS and set the SATA mode to AHCI. Please note that different Motherboards have different BIOS interfaces.

For example: For ASUS motherboard, when you boot the system, click DEL to enter BIOS. Advanced\ SATA Configuration\ SATA Mode Selection\ AHCI.

For GIGABYTE motherboard, when you boot the system, click DEL to enter BIOS. Peripherals\ Integrated SATA Controller--change to “Enabled” \ SATA Mode Selection\ AHCI.

If you partition with the system built-in tool in Win 7 or later versions, the partition after being formatted will be 4K aligned by default. You don't need to do any setup. If you still use XP system, then you will depend on a third party tool to achieve 4K alignment. 

Sorry, you need to buy one separately.

Yes, if your laptop has a SATA interface and a specific position to install it. We recommend you to replace the old hard disk drive.

We will provide firmware support when users have met any kind of problems. We don't have regular firmware updates for now.

Yes. It will breath with blue lighting when it is working.

Detach the old HDD, then place your DREVO SSD into the bracket and use the same screws you removed to secure it. Then slide DREVO SSD back into the bay and plug it in the SATA connector used by the old drive.

The 3 independent capacitors are designed to secure data when lose power.

The form factor is Non-Volatile Memory Express (NVMe) HHHL(Half Height Half Length).

The controller is SM2260 and NAND type is 3D MLC. 

The X1 PRO has equipped with high-end DRAM which will provide higher random read and write speeds.

The Ares has three working modes - S - Slow(slowest speeds with less power consumption); D - Standard(middle option) and P - Powerful.

You should firstly enter BIOS to choose the SSD as the first boot disk.
