SAFETY AND MAINTENANCE

SAFETY GUIDELINES
In order to achieve maximum safety while using your WIRELESS HEADSET, USB WIRELESS TRANSCEIVER, 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 assistance.
Do not take apart the device (doing so will void your warranty) and do not attempt to operate it under abnormal current loads.
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.
The device isolates external ambient sounds even at low volumes, resulting in lowered awareness of your external surroundings. Please remove the device when engaging in any activities that requires active awareness of your surroundings.

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 Barracuda 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. Do not use soap or harsh cleaning agents.

BATTERY WARNING

If you suspect that the Li-ion rechargeable battery inside the WIRELESS HEADSET, USB WIRELESS TRANSCEIVER may be drained (has a low charge), try charging it.
Caution: Do not 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.
