Relm Radios

RM8150 is a very tough, compact 50 watt mobile, with great specs.
256 or 512 Memory Channels256 (RM8150) and 512 (RM8125) 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 InformationThrough 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 SettingsTo 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-signalingAll 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.5/6 Programmable KeysUp to 5 (RM8150) or 6 (RM8125 )programmable keys could be set as different functions by holding or pressing on it.Lone Work and Security CheckThe 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.
Remote Kill/Stun/Activate/ReviveIf 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 CallsThe RM8125/50 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.Call AuthorizationThe radio could be programmed as TX forbidden: TX unauthorized or TX allows to be used in different positions in a group.Flexible Call OperationsTo 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.PLL Steps2.5kHz, 5kHz, and 6.25kHz could be used for channel frequency assignments for greater efficiency in frequency resources.High and Low PowerTo provide longer communications distance or less power consumption, the RM8125/50 series mobile radio offers 25 Watt and 50 Watt models.Optional Selection Tone (OST)The RM8125/50 could be programmed to temporarily select CTCSS/DCS by one pre-programmed key.Meets MIL-STD 810 C/D/E/FThe RM8125/50 is designed to meet MIL-STD 810 C/D/E/F specifications covering physical and temperature shock, vibration, low pressure, and solar radiation.Key LockWhen this function is enabled, any operations on the key will be ignored. This helps prevent the undesired operations caused by carelessness.Lowest Volume AudibilityTo prevent missed voice messages caused by the mute operation, Lowest Volume Audibility limits the lowest volume to be an audible level.Power-on Self-inspectionThe radio power-on will be stopped automatically if there are any damages to the radio’s data or hardware.High/Middle/Low Power SwitchIn each channel, RF power can be selected for different applications in programming software or manually by via utilities menu.Ignition SwitchThe radio can be set to be switched on with the ignition of the vehicle or manually for different applications.Versatile Scanning FeaturesUp to 16 scan templates for each channel allows different scan list for convenient administration in large work groups. The RM8125/50 series offers both normal and priority scan modes. Most parameters in scan could be customized.Personalized Alert TonePasswordProtection
