Leaky Communication System for Mine
■System overview
This system replaces the older ‘pager’ model of underground communication, where mines would have to go to pagers, functionally telephones hard-wired to the surface, to speak to their colleagues, either above or below ground. Not only did this system require considerably more extensive construction work and logistical detail than the leaky feeder system, as new pagers would have to be individually installed as mines grew, but was an inherently inefficient system, as all lines of communication would have to go through a single point above ground, regardless of the location of the workers attempting to communicate. This means a worker ten miles underground can easily speak to a colleague on the surface, using the antenna between them to connect the signal. This is done via a stationary telephone console such as Electronics mine telephone, a two-way radio which can be integrated into a leaky feeder system.
■Precautions for use
1. Don't forget to press the microphone switch when speaking.
2. The various function control settings of the equipment must not be changed randomly.
3. The user should strictly follow the instructions to prevent damage to the equipment.
4. If the handset fails to make a call, first check whether the battery is charged, and the battery must be under voltage. 5. Charge it in time, otherwise the battery may be damaged. If the voltage is normal and still can't talk, please send it back to the factory for repair. 6.
7. If the base station fails to talk, first check the 12V power supply voltage to see if it is normal. If 8. The voltage is normal and still can't talk, please send it back to the manufacturer for repair.
9. Pay attention to keeping the charging part of the charger clean to prevent rust and poor contact.
10. Timely remove water and dust on the panel, speakers, microphone, etc., so as not to affect the use.
11. When the battery pack is not used for a long time, it should be repeatedly charged and discharged twice to reach the rated capacity.
12. If the machine fails during operation, it cannot be unpacked and inspected underground.
