Modifying or tampering with your module’s internal components can
cause a malfunction and might invalidate the module’s warranty and
void your FCC authorization to operate it. If your module is not operating
as it should, take it to your local RadioShack store for assistance. If the
trouble is harming the telephone lines, the telephone company might
ask you to disconnect your module until you have resolved the problem.
LIGHTNING
Your module has built-in protection circuits to reduce the risk of damage
from surges in telephone line current. These protection circuits meet or
exceed the FCC requirements. However, lightning striking the telephone
lines can damage your module.
Lightning damage is not common. However, if you live in an area that
has severe electrical storms, we suggest you unplug your module dur-
ing storms to reduce the possibility of damage.
