IMPORTANT SAFETY INSTRUCTIONS

When using your telephone equipment, basic safety

precautions should always be followed to reduce the risk



1. Read and understand all instructions.

2. Follow all warnings and instructions marked on the

product.

3. Unplug this product from the wall outlet before

cleaning. Do not use liquid or aerosol cleaners. Use a

damp cloth for cleaning.

4. Do not use this product near water such as near a

bath tub, wash bowl, kitchen sink, laundry tub or a

swimming pool, or in a wet basement or shower.

5. Do not place this product on an unstable table, shelf,

stand or other unstable surfaces.

6. Avoid placing the telephone system in places with

extreme temperature, direct sunlight, or other

electrical devices. Protect your phone from moisture,

dust, corrosive liquids and fumes.

7. Slots and openings in the back or bottom of the

telephone base and handset are provided for

ventilation. To protect them from overheating, these

openings must not be blocked by placing the product

on a soft surface such as a bed, sofa or rug. This

product should never be placed near or over a radiator

or heat register. This product should not be placed in

any area where proper ventilation is not provided.

8. This product should be operated only from the type

of power source indicated on the marking label. If you

are not sure of the type of power supply in your home



9. Do not allow anything to rest on the power cord. Do not

install this product where the cord may be walked on.

10. 

through the slots in the telephone base or handset

because they may touch dangerous voltage points or

create a short circuit. Never spill liquid of any kind on

the product.

11. To reduce the risk of electric shock, do not

disassemble this product, but take it to an

authorized service facility. Opening or removing

parts of the telephone base or handset other than



voltages or other risks. Incorrect reassembling

vicinity of the leak. Under certain circumstances, a

spark may be created when the adapter is plugged

11

into the power outlet, or when the handset is replaced

in its cradle. This is a common event associated with

the closing of any electrical circuit. The user should

not plug the phone into a power outlet, and should not

put a charged handset into the cradle, if the phone is

located in an environment containing concentrations of



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.

telephone base or charger. The CHARGE light on the

handset is on during charging.

CHARGE light

Note: The display of your handset may go blank for a

short time when placing back on charge. This is the

normal operation of your handset.

16

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.

17

Power-fail backup mode operation

During power-fail backup mode, the telephone base,

answering system and all MobileConnect related

features will be disabled. The operating time is



the telephone base and the actual usage. For optimal

performance, you are not recommended to use the

handset placed in the telephone base when this mode

is on.

Using other system handsets (Recommended):

Operate the handsets the same way as usual, except

the answering system and all MobileConnect related

features which will be disabled.

Using the handset placed in the telephone base:

To maximize the operating time, you are not advised

to use this handset. If you do have to use it, make sure

you do not lift it from the telephone base. All operations

should be done with the handset placed in the

telephone base. In this case, calls can only be made and

received using the speakerphone.

• Note: the registered handset(s) will display To power BS

Press TALK-OFF when mains power interruption occurs.

Press OFF/CLEAR and then place the handset onto the main

base unit to activate the Power Fail Back-Up mode and start

up the base.
