3.9. Handling the device
Observe the following safe-handling guidelines to prevent damage to owa450:
• When setting up the device for work, place it on a level surface.
• Protect the device from environmental hazards such as extreme temperatures and overexposure to sunlight.
• When you move your device between environments with very different temperature and/or humidity ranges, condensation may
form on or within the device. To avoid damaging it, allow sufficient time for the moisture to evaporate before using the device.
• When taking the device from low-temperature conditions into a warmer environment or from high-temperature conditions into a
cooler environment, allow the device to acclimate to room temperature before turning on power.
• When disconnecting a cable, pull on its connector or on its strain-relief loop, not on the cable itself. As you pull out the
connector, keep it evenly aligned to avoid bending any connector pins. Also, before you connect a cable make sure both
connectors are correctly oriented and aligned.
3.10. For owa450 including battery backup
These models include the optional battery backup of lithium-ion. Do not dispose of the battery along with household waste. Contact your
local waste disposal agency for the address of the nearest battery deposit site.
The battery poses a burn hazard if you disassemble or handle it improperly. If the battery is damaged, electrolyte may leak from the cells
and may cause personal injury.
Keep the battery away from children.
When the battery is heated to excessive temperatures, its cells could explode or vent, posing a risk of fire.
Use only approved batteries to avoid the risk of explosion. The use of an incorrect type of battery may cause an explosion.
3.11. Part 15B EMC Notice
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
