LOCATION
Place your VTech 15850 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
15850 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.

POwER-fAIL bACkUP MODE
Power-fail mode allows your telephone system to
function in the event of a power outage. The telephone
system uses stored power from the handset’s battery to
operate.
After the power goes out, if there is already a handset
with enough charge placed in the telephone base,
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.
-OR-
If there is no handset placed in the telephone base after
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.
