Single Frequency Repeater Function (MDM-4000 Series Only)

What is it?
MDM Series mobile radios have a factory-optional feature called Single Frequency Repeater (SFR) that allows your mobile radio to be used as a repeater to help radios communicate that might fall out of normal communications range. SFR is different from traditional repeater mode in that the uplink and downlink frequencies of the repeater are the same. Your radio dealer will need to activate this feature in your MDM Series mobile radio.

How it works:
For DMR two-way radios, there are two “slots” at a single frequency, we call them “Slot 1” and “Slot 2”. Using interference cancellation technique, our DMR radio with SFR feature can use one slot to receive a call and the other slot to transmit the call on the same frequency at the same time.

Single Frequency Repeater (SFR) mode works as a very fast store and forward repeater. Radio 1 only transmits for 30 msec and then waits while the radio with SFR takes the voice data packets from radio 1 and sends them out on time slot 2 for 30 msec.

How do I use it?
Your radio dealer needs to program all your portable radios that you wish to use with the SFR feature to talk on the SAME FREQUENCY, but have one group talk on SLOT 1 and the other group that is out of reach to talk on SLOT 2. When turned on, the user of the MDM-4000 radio will only need to set the mobile radio to the channel where the SFR frequency is programmed and keep the mobile radio turned on. The radios you want to connect to the SFR channel to reach each other now just need to turn to the frequency & color code the SFR channel was programmed for and they will be able to communicate through the SFR repeater even though they are out of range when trying to reach each other directly on other channels (Simplex mode).

Why It is Used

1. In simplex mode, your signal coverage can be extended, especially in closed or isolated small areas of a signal’s dead zone or a weak signal zone.
2. Saves frequency resources. A single frequency point can set up a complete repeater system.

Precautions

Precautions for Safe Operation of this equipment.

Be careful when removing your antenna from the Radio and don’t transform your antenna or make any changes to your antenna. Strong electronic waves emitted from the Radio can have an effect on the performance of the Radio if the antenna is modified and can cause the Radio to have a defect not covered under warranty.

Don’t use other manufacturer’s accessories (such as power adaptor, microphone, external speaker microphone and earphone, etc.). Unknown or unauthorized accessories may damage the radio and void the warranty.

Don’t disassemble or reorganize the Radio. The disassembly or reorganization of your radio is punishable by law and can cause damage to the radio that will not be covered by the warranty

Don’t use frequencies you do not have a permit for.

Avoid excessive shock to the Radio. Don’t place the Radio where the direct sunlight and/or the high temperature occurs,

Do not use the radio where prohibited

Your radio emits a strong electronic wave which may have an effect on the operation of other equipment and can also be affected by those other devices.

If using radio in an area where medical equipment is being used, please get permission from relevant staff to prevent interference issues.
Be careful when using your radio in a place where computers or other electronic devices are being used because the strong electronic waves from the radio can affect this equipment.

Safety Notes & FCC

• Please keep the radio away at least 1 inch from the body.
• Do not touch antenna if it is damaged. Risk of skin burn can occur if the outside surface of antenna gets stripped out.
• Please don’t listen to the radio at a high-volume level when using earphones. Loud volume may have a lasting bad effect on your hearing.
• It is recommended to adjust the volume step by step to the level you want after you set the radio volume of the radio at a low level.
• Turn off the radio in areas where there is a strong electromagnetic force

FCC RF EXPOSURE COMPLIANCE REQUIREMENTS FOR OCCUPATIONAL USE ONLY
