7. SAFETY AND MAINTENANCE
SAFETY GUIDELINES
In order to achieve maximum safety while using your Razer Seiren 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 for assistance.
Do not take apart the device and do not attempt to operate it under abnormal current loads. Doing so
will void your warranty.
When connecting external devices, carefully plan how the wires will be placed. Protect any connected
cables from being walked on or pinched, particularly at plugs, convenience receptacles, or the point
where they exit from.
When unplugging any connected devices and/or cables, always pull on its plug or connector. Don’t
forcefully tug on its cord.
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 in order to let the temperature stabilize to an optimal level.
Listening to excessively loud volumes over extended periods of time can damage your hearing.
Furthermore, legislation of certain countries permits a maximum sound level of 86db to affect your
hearing for 8 hours a day. We therefore recommend that you reduce the volume to a comfortable
level when listening for prolonged periods of time. Please, take good care of your hearing.
MAINTENANCE AND USE
The Razer Seiren V2 Pro requires minimum maintenance to keep it in optimum condition. Once a
month we recommend you unplug all connected cables and clean it using a soft cloth or cotton swab
to prevent dirt buildup. Do not use soap or harsh cleaning agents.
