Once a radio has been upgraded it is not possible to downgrade it.
Some Hytera radios are IP67 rated, meaning that they can be immersed in 1 meter of water for 30 mins. If it is not IP67 rated (check the technical specification) take the radio out of the water and remove the battery. Put the radio in a well-ventilated area so that the radio dries out quickly. If the radio does not turn on or function correctly, return the radio to your authorized Hytera dealer for maintenance as soon as possible.
If you cannot find the technical information you require on the product listing on this website, then please speak to an authorized Hytera dealer who can support you with your request.
The PD3, PD4, PD5, and MD series radios are rated at IP54, meaning the radios are protected from limited dust ingress.
The PD6, PD7, and X1 series along with the PD712Ex and PD792Ex radios are rated at IP67, meaning the radios can be immersed in 1 meter of water for 30mins.
A USB Bulk Driver must be installed in order for the CPS to communicate with the radio
The audio jack on the radio may have been damaged. Please return the radio to your Hytera authorized dealer for maintenance.
Radios from the X1 series and the PD98x support the permanent Bluetooth discovery feature.
The short antenna is conveniently designed and easy to carry, the long antenna covers a wider communication range. Selecting the right antenna is dependent on the environment you require coverage in.
Li-ion and Ni-MH are the two different type of batteries available from Hytera.
With the DMR protocol, there are two time slots in the 12.5KHz narrowband channel which can be used as audio or data channels.
If the battery on the radio is charged, check the battery contacts on the radio. If anything is broken or twisted, return the radio to your authorized Hytera dealer for maintenance.
The Ni-MH battery is designed for 500 standard recharge & discharge cycles; a Li-ion battery is designed for 1000 standard cycles. Replace your old battery when the battery life cycle is over allowing efficient performance from your radios. Learn more about How to charge two-way radios and extend battery life
This noise often indicates the radio has been programmed incorrectly. The noise would be an indication the channel frequency programmed is out of the frequency range supported by the radio in question. Please check your settings or contact a professional engineer for help.
Please check the antenna making sure it is in good working condition, also check the antenna socket to ensure it is not damaged or loosened. If you notice damage in the socket, return the radio to your Hytera authorized dealer for maintenance.
The communication distance would be affected by the following factors:
Environment: If you use it around high buildings and large mansions, the communication range is smaller.
Weather: If you use the radio on a rainy day, the radio performance may be poor.
Power: If the power of the radio is very low, you will have a poorer communication distance.
Please check to see if the MIC is blocked preventing you from transmitting properly. If so, please return the radio to your Hytera authorized dealer for maintenance.
When the radios are at the edge of the coverage area or in an area where radio signals are interrupted or blocked, these symptoms will occur. If you are within your coverage area and there is no interruption to the radio signals, please return the radio to your Hytera authorized dealer for maintenance.
This could be a result of a poor connection between the LCD and PCB, which could have occurred due to the radio being dropped and not being used properly. Please return the radio to your Hytera authorized dealer for maintenance.

The following features are compatible with the Motorola DMR radios: Voice Calls (individual and group), Caller ID, Emergency Calls, Text Messaging, Enhanced Encryption (DMRA Standard).
Up to 64 zones can be programmed on to the portable DMR radios, this would give a maximum total of 256 channels. The maximum number of zones depends on the radio model.
The minimum frequency difference between RX frequency and TX frequency is 1.25 kHz.
100% Duty Cycle.
You can have up to 4 emergency systems.
You can program up to 200 contacts/IDs on DMR radios.
Digital Mobile Radio; Based on a TDMA (Time division multiple frequencies) Modulation protocol technology, operating in 12.5 kHz bandwidth channels, With 4 levels FSK (frequency shift keying) and advanced FEC (forward error correction) technology.
You can program up to 32 groups on the DMR radios.
With DMR Tier 2, the quick text message allows 256 characters. Radios from the PD3 series allow 64 characters.
In DMR technology, the radio will transmit for 30 milliseconds and stop for 30 milliseconds this allows the battery to last longer.
