LOCATION
Place your VTech 15750 within 2 metres of the mains
power socket and telephone socket so that the cables
will reach.
Make sure it is at least 1 metre away from other
electrical appliances to avoid interference. Your VTech
15750 works by sending radio signals between the base
and handset. The strength of the signal depends on
where you locate the base. Putting it as high as possible
ensures the best signal.
The maximum range between the base station and the
handset is approximately 300 meters.
