Dear Sir/Madam,

This equipment meets the requirements of the FCC Rules, Parts 90.203(e) and (g), as applicable.

The operator can not program transmit frequencies using the equipment’s external operation controls.

The operator can’t program transmit frequencies using the equipment’s external operation controls.

This is to certify that the requirements of 47 CFR Part 90.203(j)(4) and (5) spectrum efficiency are met by the Is Digital Radio as demonstrated by the tests conducted on the sample radio provided.

The tests show that the 4FSK data rate is in accordance with ETSI TS 102 361-1, that is 9600 bits per second in a 12.5 kHz bandwidth to satisfy the data rate requirement of 4800 bits per second per 6.25 kHz of channel bandwidth (7K60FXD emissions). Additionally the Is Digital Radio uses the AMBE+2 half-rate vocoder to compress 60 ms of normal bursts are sent in alternate 30 ms TDMA slots and so comply with the equivalence of one voice channel per 6.25 kHz bandwidth (7K60FXW emission).

Additionally the radio also meets the requirement of one voice channel per 12.5kHz of channel bandwidth for analogue speech (11k0F3E emission).

Sincerely Yours, Peter wang

Data manufacturer

The radio is a DMR dual-slot digital walkie-talkie developed and produced by my team with 1024 memory channels, full-color LCD display and full keyboard hand-tuning function. In order to make you fully understand the various advantages of the radio performance and use and maintenance methods, please read this manual carefully.

Main Features

•    Broadband walkie talkie

Support UV double segment, frequency range UHF400.000-470.000MHz / VHF136.000-174.000MHz

•    DMO True2-Slot dual time slot

Direct mode dual-slot communication achieves two groups of calls at a frequency point at the same time, so that the communication efficiency is doubled and frequency resources are saved

•    Digital and analog compatible, smooth over

Support DMR digital and analog two communication modes to ensure that the original analog products smooth transition to digital products to meet different communication needs

•    Digital signaling function

Rich calling modes that support DMR protocol, including single call, group call and all call; supports remote inhibit function and other applications

•    SMS function

Supports SMS, text editing and draft in 250 characters in Chinese and English, so that text messages calls can be sent when voice call is inconvenient

•    High sound quality

This digital two-way radio uses advanced AMBE +2TM voice processing technology to achieve high quality

•    Manual writing-frequency
