DP458 Digital Walkie Talkie

Kelixun DP485 digital walkie-talkie is designed and manufactured based on time division multiple access technology. It supports both digital and analog modes, and is compatible with existing conventional analog and most digital communication systems on the market. 抗干扰性强、功率强劲、语音清晰 。 Kelixun DP485 digital radio has strong anti-interference, strong power and clear voice . Applicable to: public utilities, industrial and commercial enterprises, transportation, property management, supermarkets, hotels and other industries.

Kelixun DP458 Digital Walkie Talkie Product Introduction:

1. Clear voice and safe communication
It adopts advanced narrowband digital voice coding technology and digital error correction technology, supports color code and voice encryption, and fully guarantees the user's call privacy. At the same time, high-end audio chips are used. In a noisy environment, or in the edge of the signal coverage area, you can get a clear and loud call effect.
2.Support analog / digital dual mode
It has two modes of digital and analog, which can realize digital / analog mixed communication, can be compatible with existing conventional analog systems, and ensure the perfect transition from analog products to digital products.
3. Pass-through dual time slots, channel capacity doubled
Adopt TDMA dual-slot communication technology, which can realize two groups of simultaneous calls on the same pair of frequencies. Compared with analog wireless communication, two sets of calls of one pair of frequencies can save users the frequency point application and use costs, and based on limited frequency resources The channel capacity can be doubled during the peak communication period, which can ease the communication pressure during multi-group communication, and ensure that users in various industries can communicate 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) and other management business functions.
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, stepped volume adjustment
The step volume switch is used to avoid the noise caused by the stepless volume switch for a long time, and the receiving volume supports the 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.Various voice call modes
Supports multiple call modes, including voice services such as single call, group call, network-wide call, and broadcast call.
9.Digital voice encryption
The 40-bit digital encryption technology using the ARC algorithm guarantees that the user's call content is not eavesdropped. Can be upgraded to advanced encryption modes such as DES and AES, compatible with more products.
10.Support multiple alarm types and modes
Optional floor alarm function, support local, regular and private alarm modes, to achieve more alarm combination applications, more secure.
11. Powerful scanning function
Supports a maximum of 128 scan lists. Each scan list can be set up with 16 channels. It supports digital-analog mixed scan, dual-priority channel scan, and automatic scan modes to meet the application needs of various users.
12, voice broadcast function
Support Chinese and English channel voice broadcast, support one-button reporting of battery power. The channel voice broadcast supports customization, and can be broadcast according to the audio source requirement mode provided by the customer.
13.Color code function
Support the color code authentication function, only the machines with the same color code can communicate. Use on color-coded relay systems. Signals with different color codes will be rejected for relay to prevent foreign signals from entering.
14.Single reception and no sub-voicing
Support only receive function (can not transmit), in analog mode, support the elimination of tails without subtones to meet the application needs of different customers in specific places.
15, multiple password protection
Supports read-write frequency passwords to prevent the machine from being randomly modified by unrelated personnel, causing communication problems.
16.Programmable button function
It has three programmable keys, and the programmable key functions can be set by software. In addition, 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
Supports offline communication in transit 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.High / low two levels of 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 power alarm
When no signal is received or there is 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.Busy channel lock
When the 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 codec
Support standard CTCSS (analog tone) and CDCSS (digital tone) to prevent interference and be compatible with more communication equipment.
25. Nine levels of adjustable noise suppression
The size of the 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 interference from other wireless signals in different communication environments.
Computer programming
Connect the radio with the computer through the data cable, you can set the frequency, function and other application parameters of the machine, and support commissioning of the radio parameters and upgrade without dismantling the machine, saving labor and time, and easy to maintain.
