Plug the charging cable from any of your PC’s USB ports to the Razer Viper V2 Pro. For best results, please fully charge the mouse before using it for the first time. A depleted battery will be fully charged in approximately 4 hours.

While charging, the status indicator will show the battery percentage of the mouse:

Icon The Razer Viper V2 Pro requires a USB connection that can supply sufficient power to charge the device. The charging process may be affected when connecting to a non-powered USB hub or non-powered USB port mostly found on keyboards and peripherals. It’s recommended to always connect the mouse directly to any of the USB ports of your PC.


The status indicator will blink red twice in repeated intervals to indicate that its battery’s power is less than 5%. This lighting sequence will repeat until the battery is drained or the mouse is connected to a PC via the charging cable.


  • A. Via wired mode
    Connect the mouse to any of your PC’s USB ports using the charging cable to use it in wired mode.
    Icon Install Razer Synapse when prompted or download the installer from razer.com/synapse
  • B. Via Razer™ Hyperspeed Wireless (2.4GHz) mode
    1. Plug the wireless USB dongle into your PC.

The Performance subtab allows you to modify the sensitivity, acceleration, and polling rate.

Sensitivity refers to the distance the cursor will travel based on how far the mouse moved. The higher the DPI, the farther the cursor will travel, given the same mouse movement distance.

Sensitivity Stages
A sensitivity stage is a preset sensitivity value. You can create up to 5 different sensitivity stages, which you can cycle through using the DPI cycle button.

Enable X-Y Sensitivity
The X-axis (horizontal) and Y-axis (vertical) use the same sensitivity values by default. However, you may set different sensitivity values for each axis by selecting the Enable X-Y Sensitivity option.

Polling Rate
The higher the polling rate, the more often the computer receives information about the status of your mouse, thus increasing the mouse pointer’s reaction time. You can switch between 125Hz (8ms), 500Hz (2ms), and 1000Hz (1ms) by selecting your desired polling rate from the options provided.

Mouse Properties
From here, you can access the Windows Mouse Properties to modify operating system settings that can directly affect your Razer Viper V2 Pro.

The Calibration subtab allows you to optimize your Razer Precision Sensor to any surface for better tracking.

Smart Tracking
Smart tracking enables you to set the distance the sensor stops tracking when lifted from its surface to avoid unwanted cursor movement. You may assign different lift-off and landing distances values by selecting the Enable Asymmetric Cut-Off.
Smart Tracking

The Power subtab allows you to manage your device’s energy consumption by setting it to power off when it has been idle for a certain amount of time. You may also adjust the required battery percentage of the mouse when entering Low Power Mode to conserve battery life.


The Profiles tab is a convenient way of managing all your profiles and linking them to your games and applications.

To achieve maximum safety while using your Razer Viper V2 Pro, we suggest that you adopt the following guidelines:

Should you have trouble operating the device properly and troubleshooting does not work, unplug the device and contact the Razer hotline or go to support.razer.com for support.

Do not take apart the device and do not attempt to operate it under abnormal current loads. Doing so will void your warranty.

Recharge the mouse before use if the Razer Viper V2 Pro has not been used for an extended period.

Keep the device away from liquid, humidity, or moisture. Operate the device only within the specific temperature range of 0°C (32°F) to 40°C (104°F). Should the temperature exceed this range, unplug and/or switch off the device to let the temperature stabilize to an optimal level.


Research has shown that long periods of repetitive motion, improper positioning of your computer peripherals, incorrect body position, and poor habits may be associated with physical discomfort and injury to nerves, tendons, and muscles. Below are some guidelines to avoid injury and ensure optimum comfort while using your Razer Viper V2 Pro..

  • Position your keyboard and monitor directly in front of you with your mouse next to it. Place your elbows next to your side, not too far away, and your keyboard within easy reach.
  • Adjust the height of your chair and table so that the keyboard and mouse are at or below elbow height.
  • Keep your feet well supported, posture straight, and your shoulders relaxed.
  • During gameplay, relax your wrist and keep it straight. If you repeatedly do the same tasks with your hands, try not to bend, extend or twist your hands for long periods.
  • Don’t rest your wrists on hard surfaces for long periods. Use a wrist rest to support your wrist while gaming.
  • Don’t sit in the same position all day. Get up, step away from your desk and do exercises to stretch your arms, shoulders, neck, and legs.
  • If you should experience any physical discomfort while using your mouse, such as pain, numbness, or tingling in your hands, wrists, elbows, shoulders, neck, or back, please consult a qualified medical doctor immediately.


The Razer Viper V2 Pro requires minimum maintenance to keep it in optimum condition. Once a month, we recommend you clean the device using a soft cloth or cotton swab to prevent dirt buildup. Don’t use soap or harsh cleaning agents.

To get the ultimate experience in movement and control, we highly recommend a premium mouse mat from Razer. Some surfaces will cause undue wear on the feet requiring constant care and eventual replacement.

Do note that the Razer Viper V2 Pro’s sensor is ‘tuned’ or optimized, especially for the Razer mouse mats. This means that the sensor has been tested extensively to confirm that the Razer Viper V2 Pro reads and tracks best on Razer mouse mats.


The Razer Viper V2 Pro contains a Li-ion rechargeable battery. In general, the life expectancy of such batteries is dependent upon usage. If you suspect that the Li-ion rechargeable battery inside the Razer Viper V2 Pro may be drained (has a low charge), try charging it.

Caution: Don’t open, mutilate, or expose to conducting materials (metal), moisture, liquid, fire, or heat. Doing so may cause batteries to leak or explode, resulting in personal injury. Battery life varies with usage.
