6. SAFETY AND MAINTENANCE
SAFETY GUIDELINES
In order to achieve maximum safety while using your Tensorbook, we suggest that you adopt
the following guidelines:
1. Should you have trouble operating the device properly and troubleshooting does not
work, unplug the device and contact Lambda Support at support@lambdal.com for
assistance.
2. Do not take apart the device (doing so may void your warranty) and do not attempt to
operate it under abnormal current loads.
3. 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.
COMFORT
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 Tensorbook.

1. Position your laptop directly in front of you. If you have an external mouse, position it
next to the laptop. Place your elbows next to your side, not too far away and your
mouse within easy reach.
2. Adjust the height of your chair and table so that the laptop is at or below elbow height.
3. Keep your feet well supported, posture straight and your shoulders relaxed.
4. During gameplay, relax your wrist and keep it straight. If you do the same tasks with
your hands repeatedly, try not to bend, extend or twist your hands for long periods.
5. Do not rest your wrists on hard surfaces for long periods. When using an external
mouse, use a wrist rest to support your wrist while gaming.
6. Do not 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.
7. If you should experience any physical discomfort while using your laptop, such as pain,
numbness, or tingling in your hands, wrists, elbows, shoulders, neck or back, please
consult a qualified medical doctor immediately.
BATTERY WARNING
The Tensorbook contains an internal, lithium-ion rechargeable battery. In general, the life
expectancy of such a battery is dependent upon usage. If you suspect that the lithium-ion
rechargeable battery inside the Tensorbook may be drained (has a low charge), try charging it.
If the battery does not recharge after several attempts, it may be non-operational.
Do not open, mutilate, or expose to conducting materials (metal), moisture, liquid, fire, or
heat. Doing so may cause the battery to leak or explode, resulting in personal injury. Do not
use or charge the battery if leaking, discolored, or deformed. Do not leave the rechargeable
battery discharged or unused for extended periods. When not using your Tensorbook battery
for more than 30 days, be sure to store the battery in a fully charged state. Do not tamper
with the battery. Dispose of the used battery according to local regulations.
