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.

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.
