RM8125 MOBILE FEATURES
512 Memory Channels
512 Channels are available. They can be separated into 16 memory banks,
of which you can quickly access pre-programmed contingency frequency plans ideal for regional-wide, cross- municipality communications.
Embedded Radio Information
Through programming software, you can get the embedded information in the radio, such as serial number,
MCU software and hardware version, last programmed method and time. The radio can save public and private embedded messages
or a welcome message for dealer and user’s to recognize.
16 Personal Templates for Channel Settings
To provide personalized communication and adapt to different applications, up to 16 personal templates can be selected for channel settings.
In each template, there are many different features that can switched on or off, such as VOX, TX conditions, Call Codes, and so on.
Full Built-in Tone-signaling
All tone-signaling encoder/decoder are built-in, such as CTCSS, DCS, DTMF, 2-Tone or 5-Tone. A wide variety of selective calling systems are available
to call specific station or control a repeater.
6 Programmable Keys
Up 6 Programmable keys could be set as different functions by holding or pressing on it.
Lone Work and Security Check
The radio enters emergency mode if you do not respond to a warning call (Lone Work) or an inquire code (Security Check), adding security
and safety for individuals who work remotely and alone.
If the radio is killed or stunned, all attempts on operation by the user will be ignored. The radio will be activated or revived only when it receives the correct code.
Multiple Emergency Calls
The RM8125 can be programmed to different kinds of sound emergency call, when the emergency siren is enabled, the radio will transmit emergency
ANI or sound continuously.
The radio could be programmed as TX forbidden: TX unauthorized or TX allows to be used in different positions in a group.
Flexible Call Operations
To achieve more efficiency in a dispatch situation, a missed call can be transferred to a pre-programmed portable radio or directly
call back from a temporarily saved directory.
2.5kHz, 5kHz, and 6.25kHz could be used for channel frequency assignments for greater efficiency in frequency resources.
High and Low Power
To provide longer communications distance or less power consumption, the RM8125 series mobile radio offers 25 Watt models.
Optional Selection Tone (OST)
The RM8125 could be programmed to temporarily select CTCSS/DCS by one pre-programmed key.Meets MIL-STD 810 C/D/E/F
The RM8125 is designed to meet MIL-STD 810 C/D/E/F specifications covering physical and temperature shock, vibration, low pressure, and solar radiation.
Key Lock When this function is enabled, any operations on the key will be ignored. This helps prevent the undesired operations caused by carelessness.
Lowest Volume Audibility
To prevent missed voice messages caused by the mute operation, Lowest Volume Audibility limits the lowest volume to be an audible level.
The radio power-on will be stopped automatically if there are any damages to the radio’s data or hardware.
High/Middle/Low Power Switch
In each channel, RF power can be selected for different applications in programming software or manually by via utilities menu.
The radio can be set to be switched on with the ignition of the vehicle or manually for different applications.
Versatile Scanning Features
Up to 16 scan templates for each channel allows different scan list for convenient administration in large work groups.
The RM8125 series offers both normal and priority scan modes. Most parameters in scan could be customized.
