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.
When the radios are at the edge of the coverage area or in an area where radio signals are interrupted or blocked, these symptom 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 authorised dealer for maintenance.
Please check to see if the MIC is blocked preventing you from transmitting properly. If so, please return the radio to your Hytera authorised dealer for maintenance.
The minimum frequency difference between RX frequency and TX frequency is 1.25 kHz.
You can program up to 200 contact/IDs on DMR radios.
Digital Mobile Radio; Based on a TDMA (Time division multiple frequency) Modulation protocol technology, operating in 12.5 kHz bandwidth channels, With 4 levels FSK (frequency shift keying) and advanced FEC (forward error correction) technology.
Follow the USB installation instructions located on Hytera Website (you need to install the USB bulk driver).
You can program upto 32 groups on the DMR radios.
The communication distance would be affected by 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 maybe poor.
- Power: If the power of the radio is very low, you will have a poorer communication distance.
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 a damage in the socket return the radio to your Hytera authorised dealer for maintenance.
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.
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.
With the DMR Tier 2 the quick text message allow 256 characters. Radios from the PD3 series allow 64 characters.
Radios radiate from their antenna at the RF frequency selected and the configured power level. In order to use the radio safely, hold the radio in a vertical position and keep about 2-5 centimetres distance from the radio. For more information about using a radio safely refer to the user manual for the radio in question.
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 authorised Hytera dealer for maintenance.
With the DMR protocol there are two time slots in the 12.5KHz narrow band channel which can be used as audio or data channels.
Li-ion and Ni-MH are the two different type of batteries available from Hytera.
The short antenna is conveniently designed and easy to carry, the long antenna covers wider communication range. Selecting the right antenna is dependent on the environment you require coverage in.
Radios from the X1 series and the PD98x support the permanent Bluetooth discovery feature.
The audio jack in the radio may have been damaged. Please return the radio to your Hytera authorised dealer for maintenance.
In DMR technology, the radio will transmit for 30 milliseconds and stop for 30 millisecond this allows the battery to last longer.
The CPS has been tested on the following operating systems: Windows XP/2000 (32 bits only), Windows Vista (32 bits only), Windows 7 (32 & 64 bit OS, Windows 8.1 (64 bit OS), Windows 10 (32 & 64 bit OS).
A USB Bulk Driver must be installed in order for the CPS to communicate with the radio.
|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 PD715Ex and PD795Ex radios are rated at IP67, meaning the radios can be immersed in 1 metre of water for 30mins.
|Some Hytera radios are IP67 rated, meaning that they can be immersed in 1 metre 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 authorised Hytera dealer for maintenance as soon as possible.|
|Once a radio has been upgraded it is not possible to downgrade it.|
