2.2.7 Upgrades
Only install system upgrades that are specifically intended for this device. Installing other up-
grades can damage the system or violate safety standards and radio interference regulations.
2.2.8 Cleaning
Before cleaning, unplug the AC line connector. Do not use scouring powder or solvents harm-
ful to plastics.
Do not allow liquids to penetrate into the interior of the CELLX Box. A dry cloth suffices for
cleaning the housing surface. A cloth dipped in water containing a mild detergent and then
wrung out well can be used for heavier stains.
2.2.9 Potentially explosive atmospheres
Do not use this product in an area where a potentially explosive atmosphere exists.
2.2.10 Radio wave exposure information
This product is a low-power radio transmitter and receiver. During operation, it emits low lev-
els of radio frequency energy.
Several organizations, e.g. ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) and IEEE (The Institute of Electrical and Electronics Engineers Inc.) developed safety
guidelines about permitted levels of radio wave exposure for the general population, based
on thorough scientific studies.
To meet the maximum permissible value for radio wave exposure, a distance of 20 centime-
ters must be kept if running one mobile channel, and an additional 20 centimeters for every
further mobile channel.
2.2.11 Personal medical devices
Radio waves may affect the operation of cardiac pacemakers and other implanted equip-
ment. To limit the risk, a distance of 20 centimeters must be kept if running one mobile chan-
nel, and an additional 20 centimeters for every further mobile channel. If you suspect that
interference is taking place, immediately move away from the device.
2.2.12 Environmental considerations
Take care to ensure proper disposal of the CELLX Box when it is no longer to be used.
2.2.13 Protecting the operating system
Changing configuration data may lead to malfunctions and/or misrouting, as well as possible
consequential damage. Make changes at your own risk. TELES is not liable for any damage
resulting from, or in relation to, such changes. Please thoroughly check any changes you or
a third party have made to your configuration!
Make sure the flash disk contains enough storage space. Download log files and delete them
