Using AC Adapter : Solid Green Using internal battery : Solid ORANGE Using internal battery and battery is week : Solid Red 1) 2) 3) 2. If the radio service is not available or radio signal is too weak to detect;

The SIGNAL LED is Red. (No Service status) 3. When the phone is succeeded in getting the service, SIGNAL LED indicates the strength of the signal. 1) Lifting handset, dial tone is heard and you can enter a phone number.

(Not entering any key for 15 seconds (In the overlap dial mode, it may take over 15 seconds.) warning tone will be produced)

*) If Hot Line function is enabled, busy tone is not produced and hot line number is automatically connected.

*) While having maintenance request order or lock order from the main system, neither dial tone nor busy tone is produced. Instead of them, the lock tone(pi-pi-pi) will be heard one time and there will be no sound and both of MODE LED and POWER LED will be blinking with GREEN color simultaneously. 3.2 Placing a call When lifting handset of the connected phone ("off hook"), the terminal determines whether cellular service is available. If it is available, dial tone is produced and a number can be dialed normally. If phone service is not available, SIGNAL LED of the terminal will be red and no dial tone will be heard. 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 hook. 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. 14 LG CDMA Fixed Wireless Terminal LST-250(F)/2500(F) 3.6 Dial Delay(Enblock mode only) The terminal waits 5 seconds before transmitting the dialed telephone number into the cellular network. 3.7 Emergency Call(Enblock mode only) 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 phone, the line will be still connected, so if the caller picks up the phone 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 including 911-even if your telephone is locked* or restricted*. Please check the available emergency call number with your service provider.

*) Transmit Lock or Transmit Restrict features have a meaning only in Enblock mode. 15 LG CDMA Fixed Wireless Terminal LST-250(F)/2500(F) 44.. SSyysstteemm FFeeaattuurreess 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 Dial Delay Time(Enblock mode only) When placing a call, the phone number is sent over the network after last digit is dialed. In order to insure adequate time for dialing the last digit, a delay of 5 seconds is programmed into the terminal. 4.3 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 45 seconds, a ROH tone emits from the receiver for a period of 60 seconds.(In the overlap dial mode, above 45 seconds or 60 seconds may be different according to the system.)

( This feature may be available or not by country specification.) 4.4 Special Cellular Services 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 entered, 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 call. Other providers may require entering the codes involving digits 1-9, *, and # to answer a waiting call. Three-way Conference Calls - For three-way conference calls, a hook-flash transmits the SEND command. Please contact your cellular service provider for more information on using this service. 16 LG CDMA Fixed Wireless Terminal LST-250(F)/2500(F) F Example Dial the first number and wait until connected;

When connected, give hook-flash and dial the second number and give one more hook-flash to be connected;

When the second call is connected, give hook flash to complete a 3-way conference call. Voice Mail Use voice mail service in the same manner as you would on a regular telephone. If you have a new voice-mail message, the WLL-terminal transmits a special Voice-Mail Notification Ring (1sec On / 6sec Off default) and Mode LED is blinking (0.5sec On/0.5sec Off). Please contact your cellular service provider for more information on using Voice Mail or to change Voice-Mail Ring pattern. Caller ID LST-250(F)/2500(F) can support Caller ID service if you have a telephone with Caller ID feature. Please contact your cellular service provider for more information on using this service. 4.5 Applications Data Communication - LST-250(F)/2500(F) is capable of transmitting and receiving IS-707 Fax or modem communications. For data communications, you will need a data communication kit and a PC Fax software diskette where needed. For further information, please contact our authorized service dealer. Multi-extension Installations - For a multi-extension installation, make sure that all the extensions are on-hook. If one extension is off-hook (not hung up), none of the extensions on that line will ring when a call is being received. 17 LG CDMA Fixed Wireless Terminal LST-250(F)/2500(F) 55..
