1.1 Safety Instruction
WARNING/CAUTION
To reduce the risk of fire or electric shock, do not
expose this product to rain or moisture. Do not use
this product near swimming pools or other water
bodies.
IMPORTANT
Before installing or operating this product read this
information.
1.2 Optimal Phone Performance
▶
Do not operate your product when holding the
antenna, or when someone is within four inches
(ten centimeters) of the antenna. Holding the
antenna affects call quality and may cause the
telephone to operate at a higher power level than
needed.
▶
For the best call quality, keep the antenna free from
obstructions and position the antenna straight up.
▶
Do not use the phone with a damaged antenna.
Have your antenna replaced by a qualified
technician immediately. Use only the Authorized
LGE Service Center-approved antenna. Non-
approved antennas, modifications, or attachments
could impair call quality, damage the phone.
▶
RF energy may affect improperly installed or
inadequately shielded personal medical devices
such as pace makers, hospital monitor. Consult the
manufacturer of any personal medical devices to
determine if they are adequately shielded from
external RF energy. Turn your terminal OFF in
health care facilities when any regulations posted in
the areas instruct you to do so.
Hospitals or health care facilities may be using
equipment that could be sensitive to external RF
energy.
▶
If this equipment does cause harmful interference
to radio or television reception, which can be
determined by turning the equipment off and on,
the user is encouraged to try to correct the
interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the distance between the radio or
television and the telephone.
- Connect the equipment into an outlet on a circuit
different from that to which the terminal is
connected.
- Consult your experienced radio/TV technician of

4.1 Hook Flash
When the terminal receives a hook-flash from the
connected telephone device, it will automatically
allow:
1. For producing dial tone again after a phone
number has been dialed without connection.
2. The use of special cellular services which may be
available in your cellular service area.
Note:
- Hook-flash is accomplished in a call through either
pressing the dedicated hook-flash key which is
available on some phones or through a rapid
single press of the hang-up mechanism upon
which the handset rests when the phone is hung
up.
4.2 ROH (Receiver Off Hook)
If the telephone equipment remains “off-hook”,
meaning that the handset is left off of its cradle as it
would be when you hang up, with no dialing activity
for about 60 seconds, a ROH tone emits from the
receiver for a period of 60 seconds.
This feature may be different or not by country
specification.
4.3 System Features
Many cellular systems offer special services such as
call waiting, call forwarding, etc. You can purchase
these services from your cellular service provider.
There are certain dialing sequences to be earned,
which vary from service provider to service provider.
The service provider will provide the dialing
instructions for your system.
Call Forwarding - An incoming call can be delivered to
another telephone number programmed. Please
contact your cellular service provider to use this
feature.
Call Waiting - You can receive another incoming call
during a call.
In this case, you will hear beep tone and then you can
connect the second call holding the first call by
entering a code required by cellular service provider.
Your cellular service provider may require hook-flash
(a quick, simulated “hang up”) to answer the waiting
System Features
System Features
3.3 Receiving a Call
The connected telephone rings when an incoming call
is detected.
Pick up the handset and begin talking.
3.4 Ending a Call
When you have completed the call, place the handset
back on telephone. Also you can hook flash more than
about 1 second to end a call and place a new call
without hanging up the handset.
3.5 Warning Tone after Remote
Disconnect
A warning tone may be heard in the telephone after a
remote party hangs up from a call, allowing another
call to be initiated after hook-flash.
3.6 Emergency Call
When emergency call number is connected once, it will
not be terminated unless the called party disconnects
the call (Emergency Call Hold Service).
Therefore even caller hangs up the telephone, the line
will be still connected, so if the caller picks up the
telephone again, he can continue talking.
If emergency call is connected, cellular service is not
supported.
As long as your telephone is registered on a system,
you can place a call to emergency number even if your
telephone is locked or restricted.
Please check the available emergency call number with
your service provider.
3.7 Power Off
When you don’t need to use terminal anymore, you
should do power off before removing AC/DC adapter
cable.
If you do terminal power off, Press Power key for 3
seconds. If so, the terminal will LED off and stop all
operations. Then you shall separate External Power
jack from Terminal.

- Check that the AC power source.
- Check that the Barrel Plug of the Power Supply is
properly inserted into the terminal.
- Check that the terminal Power Supply is properly
plugged into the electrical outlet or power source.
