main functions
&Nbsp; in addition to being used as an ordinary telephone, this machine also has the following functions:
1
When used as a called machine, under the trigger of bell flow, the machine first turns on the power supply in the machine, amplifies the ringing tone and broadcasts it through the loudspeaker
At the same time, count the ringing tone after several rings (it can be set to 1-8 times by the user, and 3 times when leaving the factory) The machine will automatically pick up and send out a & ldquo; Ding Dong Ding & rdquo; prompt tone
After hearing the prompt tone, the caller can make a call broadcast, and its sound will be broadcast to nearby listeners through the speaker of the machine

After detecting one of the following situations, the public address part of the machine will automatically exit the public address call, go offline with the telephone line and enter the standby state

&Nbsp; (a) the number of rings does not reach the set value, and the caller terminates the call

&Nbsp; (b) after the caller hangs up after the call broadcast, the local machine receives the busy tone signal or reverse polarity signal provided by the switch

&Nbsp; (c) the silence time of the caller during broadcasting is greater than 80s

&Nbsp; (d) during the broadcast, one of the calling party and the called party drops the line for more than 80s

&Nbsp; (E) someone lifts the handle of the phone to make a call

3
During the call, the called can also take off the handle to talk with the caller
At this time, the public address system will turn off automatically

4
The called can also make an off hook call during ringing
