<Battery Connection >

First, slow down the terminal slide switch and unscrew.

To connect battery, disassemble terminal like above figure.

Battery connectors groove must be slid into the jack like above figure. 1. The POWER LED indicates the present status:

Using AC Adapter : Solid GREEN

Using internal battery : Solid ORANGE

Using internal battery and battery is weak capacity: Solid RED 2. When the terminal succeeded in getting the service, SIGNAL LED indi-

cates the strength of the signal(Table 1). Lifting handset on telephone, dial tone is heard and you can enter a phone number. Note:

- Not entering any key for 15 seconds warning tone will be produced.

- In the overlap dial mode, it may take over 15seconds.

- If Hot Line function is enabled, busy tone is not produced and hot line number is auto-

matically connected.

- While having maintenance request order or lock order from the 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 All LED s will be blinking with GREEN color simul-

taneously. 3. If the radio service is not available or radio signal is too weak to detect:

The SIGNAL LED is RED. (No Service status) Placing a call When lifting handset of the connected telephone (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. If user presses #button after dialed the number, the terminal makes a call immediately. 20 21 Basic Operation Basic Operation Receiving a call Power Off The connected telephone rings when an incoming call is detected. Pick up the handset and begin talking. When you need not to use terminal anymore, you should do power off before removing AC/DC adapter cable. Execute the Power Off 1. Press #+ #+ 9continuously to enter power off mode. 2. Press #and 1to ready power off. 3. Press *to execute power off. 4. After few seconds, all LED will off. 5. Turn off backup battery switch and remove AC/DC power adapter cable. 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. 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. 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. 22 23 System Features System Features 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 with-

out 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. 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. After ROH tone, Line Lock Out Tone emits from receiver for a peri-

od of 60 seconds. This feature may be different or not by country specification. System Features Many cellular systems offer special services such as call waiting, call forward-

ing, 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 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.

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(4sec On / 1sec 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-255(F) can support caller ID service if you have a telephone with Caller ID feature.

*During a call, CID is not displayed. Please contact your cellular service provider for more information on using this service. 24 25 System Features Programming Applications Data Communication - LST-255(F) is capable of transmitting and receiving IS-707A FAX or modem communications. For data communications, you will need a standard RS-232C cable or a stan-
