● Exercise caution when using tools to prevent injuries.
● If the position for installing the device is higher than your shoulders, use a
stacker to lift the device to prevent it from falling on top of you.
● High-voltage power supply provides power for device operation. Do not touch
high-voltage cables directly or through conductive materials. This may cause
danger of electrocution.
● Before powering on a device, ground it to prevent injuries.
● Do not use the ladder unsupervised. Have someone else hold the ladder
steady to prevent accidents.
● Do not view the open optical port directly when installing, testing, or
