Radio Interference
The on-board battery charger generates and can radiate radio frequency energy. The
equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to FCC rules, Part 15.
With proper installation, there should be no interference with any radio communications,
either with the display's own receiver or other radio-controlled devices in the
immediate area. However, if it is determined that this device may be the cause of radio
interference, try to correct the interference with one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to an AC outlet on a circuit different from the receiver.
Battery & Charging Safety
Note: The following lists are general safety instructions when working with lead-acid
batteries. Some of the safety considerations are not applicable to the sealed
batteries provided with the display as those batteries are self-contained and
cannot be opened, and they are safer than automotive batteries that require
servicing. Exercise caution, however, when working with any lead-acid battery.
Personal Safety Precautions
• Someone should be within range of your voice or close enough to come to your aid
when you work near a lead-acid battery.
• Have plenty of fresh water and soap nearby in case battery acid contacts your skin,
clothing, or eyes.
• Wear complete eye protection and clothing protection. Avoid touching your eyes
while working near the battery.
• If battery acid does contact skin or clothing, wash immediately with soap and water.
If you get acid in your eye, immediately flood the eye with running cold water for at
least 10 minutes, and get medical attention immediately.
• NEVER smoke or allow a spark or flame near the battery.
