This equipment generates, uses and can generate 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 the interference will not occur in a
particular installation. If this equipment does cause harmful

When condensation occurs inside the transceiver:
Condensation may occur inside the transceiver when the room is
warmed using a heater on a cold day or when the transceiver is
quickly moved from a cold location to a warm location. When
condensation occurs, the microcomputer and/or the transmit/receive
circuits may become unstable, resulting in transceiver malfunction. If
this happens, turn OFF the transceiver and wait for a while. When the
condensed droplets disappear, the transceiver will function normally.
