DP485 digital radio

Kelixun DP485 is a professional digital handheld terminal designed and manufactured based on time division multiple access technology. It supports both digital and analog modes, strong anti-interference, strong power, clear voice, GPS positioning, record query, remote control, etc. Applicable industries: public utilities, industrial and commercial enterprises, transportation, property management, supermarkets, hotels, etc.

Kelixun DP485 Digital Walkie Talkie Product Introduction:

1, clear voice, communication security using advanced narrow-band digital voice coding technology and digital error correction technology, support for color coding and voice encryption, to ensure the user's call privacy; at the same time, select high-end audio chips, 40mm large speakers with unique acoustic cavity structure Designed to make the phone clear and loud in both noisy environments and at the edge of signal coverage.
2. Supports analog / digital dual mode. It has two modes: digital and analog. It can realize digital / analog mixed communication. It can be compatible with existing conventional analog systems to ensure a perfect transition from analog products to digital products.
3. Through dual time slots, channel capacity is doubled. TDMA dual time slot communication technology can be used to achieve two simultaneous calls at the same pair of frequencies. Compared with analog wireless communication, two sets of calls at one frequency can save users frequency points. And the use cost, the channel capacity can be doubled on the basis of limited frequency resources, and the communication pressure during multi-group communication can be alleviated during the peak communication period, ensuring that users in all industries can dispatch commands and instructions in real time.
4, powerful, a variety of high-end functions can be customized with customization (customization optional)
Supports high-end application functions such as reverse playback, roaming, GPS positioning, online registration, launch interruption, and virtual clusters. In conjunction with our company's commercial digital scheduling management system, it enables users to implement such functions as IP interconnection, online reminders, cross-region roaming, GPS positioning, and inversion. Ground alarm and other functions.
5. Rich scheduling management functions support remote management (decoding), halo (decoding), activation (decoding), walkie-talkie detection, independent work and remote monitoring (decoding).
6. Powerful upgradeable expansion space (customized)
Supports real-time clock function, can be upgraded to expand 200-400 hours recording function, can broadcast the current time with one click.
7. The stepped volume adjustment uses a stepped volume switch to avoid noise caused by the stepless volume switch for a long time, and the receiving volume supports minimum / maximum / fixed volume settings. A variety of different tones can be set individually. You can turn off / on the volume with one click.
8. Multiple voice call modes support multiple call modes, including voice services such as single call, group call, network-wide call, and broadcast call.
9. Digital voice encryption adopts ARC algorithm's 40-bit digital encryption technology to ensure that the contents of the user's call are not eavesdropped. Can be upgraded to advanced encryption modes such as DES and AES, compatible with more products.
10. Supports multiple alarm types and modes. The optional floor alarm function is supported. Local, conventional, and private alarm modes are supported. More alarm combinations can be implemented, ensuring more security.
11. Powerful scanning function supports up to 128 scan lists, each scan list can be set up to 16 channels, supports digital-analog mixed scan, dual priority channel scan, automatic scan and other modes to meet the application needs of various users.
12, voice broadcast function supports Chinese and English channel voice broadcast, support one-click report battery power function. The channel voice broadcast supports customization, and can be broadcast according to the audio source requirement mode provided by the customer.
13. The color code function supports the color code authentication function. Only machines with the same color code can communicate with each other. Use on color-coded relay systems. Signals with different color codes will be rejected for relay to prevent foreign signals from entering.
14.Single receiving and no subtone cancellation tail function support only receiving function (can not transmit), in analog mode, support the elimination of tail without subtone, to meet the application needs of different customers in specific places.
15. A variety of password protection supports read-write frequency passwords to prevent the machine from being arbitrarily modified by unrelated personnel, causing communication problems.
16. Programmable key function There are three programmable keys. The programmable key functions can be set by software. Each key supports two modes of short press and long press to realize different functions and meet more convenient control requirements.
17. Support a variety of signaling in analog mode (optional function)
In analog mode, it supports 2-tone / 5-tone, DTMF, MDC and other signaling, which is compatible with customers' existing analog dispatching systems and more terminal equipment.
18. Offline and monitoring functions support offline communication in the transfer mode. Press the monitor function key to forcibly turn on the squelch circuit and monitor all signals on the current channel. This function is particularly effective for receiving weak signals, and it can also be used when troubleshooting machine problems.
19. Channel spacing is optional (wide / narrowband switching)
In analog mode, 25KHz / 20KHz / 12.5KHz multiple channel spacing options are provided, compatible with more products, and more channels can be accommodated under limited frequency resources.
20. The high and low power can be switched. You can adjust the high and low power of the communication at any time through the set shortcut keys to meet the needs of different communication distances, save battery power and reduce radiation.
21. Automatic power saving, low battery alarm When no signal is received or no operation, the machine will automatically enter the power saving sleep state to save power consumption. When the battery power is low, there will be a sound and an indicator light. The battery power can also be announced through a shortcut button, so as to control the power status in time and remind the user to charge as soon as possible.
22. When the busy channel lock machine is in the receiving state, it is forbidden to transmit signals to the busy channel to prevent the channel from being interfered. This function can prevent users from preempting the relay channel and interfering with each other in the communication mode with the relay station.
23.TOT
After turning on this function, you can limit the time of each transmission of the radio. This will not only extend the battery life, reduce the degree of channel congestion, but also avoid accidentally occupying the channel by pressing the transmission button accidentally (the user is not aware). phenomenon.
24. CTCSS / CDCSS codecs support standard CTCSS (analog subtone) and CDCSS (digital subtone) to prevent interference and be compatible with more communication equipment.
25. Nine-level squelch The adjustable squelch level determines where the squelch is turned off and on. It supports multi-level selection of the squelch level from 1 (light) to 9 (deep) in order to avoid the need for different communication environments Interference from other wireless signals.
26. Computer programming Connect the walkie-talkie to the computer through a data cable, which can set the frequency, function and other application parameters of the machine, and support the debugging of the radio frequency parameters and upgrade of the walkie-talkie without disassembling the machine, saving labor and time and facilitating maintenance.
