Sound and light hands-free loudspeaker phone
This phone is suitable for steel rolling workshops in steel plants, blast furnace plants, refineries, nuclear power plants, offshore oil platforms, tunnel construction sites, port bridges, next to shield machines and other Very noisy places
The phone is designed to be used in environments with special requirements for moisture resistance, fire protection, noise resistance, dust resistance, freezing protection, and damage resistance. The whole machine is designed according to the stability requirements in sub-zero to super-zero environments, and its technical indicators are at the leading international level.
Loudspeaker function
When the environmental noise exceeds decibels, the ring tone of ordinary telephones often cannot be heard by the staff, resulting in production scheduling instructions not being conveyed in a timely manner, resulting in economic losses. The ringing sound can be amplified and played through the speaker. At the same time, the ringtones are counted. After a number of rings (set to times at the factory), the unit automatically picks up the phone. The caller can broadcast the call. The sound will be broadcast to nearby work and maintenance personnel through the speaker of the unit. .
After detecting one of the following situations, the loudspeaker part of this unit will automatically exit the loudspeaker call, go offline with the telephone line, and enter standby mode.
If the number of rings does not reach the set value, the caller terminates the call. After the caller completes the call broadcast and hangs up, the unit receives a busy tone signal or a reverse polarity signal provided by the switch. The silence time is greater than when calling. The person lifts the handle of the phone to make a call.
During the call, the called party can also take off the handset to talk to the caller. At this time, the loudspeaker system will automatically turn off.
The called party can also pick up the phone and talk during the ringing period.
The power of this machine is automatically turned off during standby, and the power is only turned on when triggered by ring current, making the machine work safer and more reliably.

, with three-level waterproof and dustproof functions, the whole machine level reaches the national standard/
, the phone has good stability, strong anti-interference ability, and complies with the national standard/ 2. Operation and use
Use in tunnels Take the construction unit as an example
Constructor Zhang San at the operation point should contact Li Si at the operation point. The two people with the most contacts are in a group
Press the white hands-free button directly to talk. If you want to talk to other colleagues, you can dial or represent Other different colleague numbers.
At the critical moment when an emergency occurs at the construction site, you can press the red button, and all extension numbers in the network will make emergency calls and flash lights
. When answering the phone, when there is an incoming call, the phone will ring, press Press the speakerphone to talk to the other party. After the call is completed, tap the handsfree button
. To make a call, press the speakerphone and follow the dialing method of an ordinary telephone to talk to the other party
. Save the call. Enter the number, take off the handle, press the storage key, enter the number to be stored, press the storage key, press any key as the address to store the number, hang up
, extract the number, take off the handle, press the extraction key, press where You can dial the memory number in the memory by pressing the required number key.
The series of telephones can also be composed of multiple telephones to form a ring network. No switch is needed to realize point-to-point and point-to-face calls. Eight pairs of telephone lines form a loop. Telephones can make arbitrary calls or group calls between telephones. A group of people can talk online at the same time on the entire ring, and the call distance can be up to kilometers. And people within the entire ring can talk to telephones outside the ring.
