For Good Reception
To assure good reception, note the
following:
• Communicate with the cell phone within
the line-of-sight distance of 10 m (30
ft). The communication range becomes
shorter depending on the surrounding
environment. The communication
range also becomes shorter when there
is an obstacle between this unit and
the cell phone. The above maximum
communication range (10 m) is not
always assured.
• A broadcast station or walkie-talkie
located nearby can interfere with
communication due to a too strong
signal.
