LOCATION
Place your VTech 17850 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 17850 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 metres.

the telephone system enters battery backup mode
automatically. That handset screen shows Powering
base... Don’t pick up. All other handset screens show
Battery backup mode.

the power goes out, all handsets show Out of range OR
no power at base and Put HS on base to power base
alternatively. Place any handset with enough charge in
the telephone base. Its screen shows Powering base...
Don’t pick up. All other handset screens show Battery
backup mode.
Note: A handset which does not have enough charge to
power up the base, its screen shows Out of range OR no
power at base and Not enough battery to power base
alternatively after the power goes out. Find another system
handset that has enough charge to activate the mode.
