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.

100% Duty Cycle.

You can have up to 4 emergency systems.

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.

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.

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 following features are compatible with the Motorola DMR radios: Voice Calls (individual and group), Caller ID, Emergency Calls, Text Messaging, Enhanced Encryption (DMRA Standard).
