FCC REGULATIONS  
FCC Part 68  
This equipment may not be used on  
coin service provided by the phone  
company or Party Lines.  
The FCC requires that you connect  
your cordless telephone to nationwide  
telephone network through a modular  
telephone jack (USOC RJ11C, RJ11W  
or RJ14).  
The REN is useful in determining the  
number of devices you may connect  
to your telephone line and still enable  
the devices to ring when you receive  
a call. The general rule is that the REN  
value should not exceed 5.0A total;  
however, contact your local telephone  
company for the specific number in  
your area.  
Your local telephone company may  
discontinue your service if your  
equipment causes harm to the  
telephonenetwork. Theywillnotifyyou

Duringnotification,youwillbeinformed  
of your right to file a complaint with the  
FCC.  
Your VT 1511 is designed to operate  
at the maximum power allowed by the  
FCC. This means your handset can  
communicate with the base unit only  
over a certain distance – which will  
depend on the location of the base unit  
and handset, weather, and the  
construction and layout of your home  
or office.  
Occasionally, your local telephone  
company may make changes in its  
facilities, equipment, operation, or  
procedures that could affect the  
operation of your equipment. If so, you  
will be given advance notice of the  
change to give you an opportunity to  
maintain uninterrupted service.  
The base unit contains no user  
serviceable parts.  
The handset  
contains a user replaceable battery  
pack.  
If it is determined that your telephone  
equipment is malfunctioning, the FCC  
requires that it not be used and that  
it be unplugged from the modular jack  
until the problem has been corrected.  
Repairs to this telephone equipment  
can only be made by the manufacturer  
or its authorized agents or by others  
who may be authorized by the FCC.  
For repair procedures, follow the  
instructions outlined under the  
manufacturer’s Limited Warranty.

THE BATTERY PACK  
Spare Battery Charger  
Power Backup Function  
The VT 1511 has a built-in spare  
battery charger, which is located in the  
base unit.  
When a spare battery pack is installed  
in the base unit, the VT 1511 uses this  
battery pack to provide operational  
backup in case of a power failure. If  
you have a fully charged battery pack  
in the spare battery charger and there  
is a power outage, you will still be able  
to place and receive calls on the  
headset for up to 5 hours. When power  
backup mode is active, the POWER  
LED will flash slowly.  
Note:  
In order to benefit from this feature,  
you must obtain an optional spare  
battery from an authorized dealer,  
or by contacting VTech Com-  
munications at 1-800-595-9511.  
Installation  
Replacing a Drained Headset  
Battery  
1. Open the spare battery charger in  
the base unit.  
The spare battery pack can also be  
used to replace a drained headset  
battery pack to ensure uninterrupted  
use. Be sure to put the drained battery  
pack in the spare battery charger for  
recharging.  
2. Place a battery pack in the spare  
battery charger. Make sure the  
metal contacts on the battery are  
aligned with the contacts in the  
spare battery charger.  
Please note that the spare battery  
compartment charges at a slower rate  
than a battery pack charging in the  
headset (via the remote charging  
stand). It takes 24 hours to fully charge  
a battery pack in the spare battery  
charger.
