FAQ – General

What is the FCC narrowband mandate?

On January 1, 2013 the FCC began enforcing its mandate that all business, industrial, educational, health care and construction users of business radio frequencies must migrate to 12.5 kHz spread spectrum equipment from legacy radios operating at 25 kHz spread… more

What is the warranty on the products?

All radios and accessories have a one year over-the-counter exchange (from date of purchase).

Do the radios require an FCC license?

Yes. The RDX, RM, CLP, and CLS Series require an FCC license. The DTR and DLR do not. The cost is approximately $110 for a 10 year license plus and additional $220 for the application fee and frequency coordinator. It is a very easy process. License is per company, not location. All licensing information comes with the purchase of the radios to the end user.

Can the radios be repaired if needed?

Yes. For out of warranty repair, have your customer call the Motorola Repair Depot at 800-227-6772.

What does Mil Spec 810 mean?

810 is a series of tests in the Military Specifications manual. C, D, E, and F are particular test conditions under section 810. The RM, RDX, CLP, CLS, DTR and DLR radios have met or exceeded Mil Spec 810 C through F. These tests consist of Shock, Rain, Temperature Shock, Sand and Dust Intrusion, Extreme Temperatures, Humidity and Salt Fog.

Is it easy to program the radios?

Yes. The CLS, CLP, RM, RDX, DTR and DLR radios are all field programmable. We are able to supply a simple initial set up guide along with troubleshooting information which includes the simple steps to program the radios.

Which radio is best for my application?

The environment where you use the radios will determine what band (VHF or UHF) will serve you best. How much coverage you desire will determine the power you need. The number of talk groups you have will determine how many channels are best suited for your use. Example: If mostly indoors in a 3 story, 200,000 s.f. building with plans to use 4 talk groups – two good options for this application would be the RMU2040 or the CLS1410.

Do current Motorola models talk to older models and other brands?

Yes, as long as the frequencies and codes match. Analog radios talk to analog radios – not digital.

How many radios can be used together?

There is no limit.

Which is better – VHF or UHF?

Depends on the terrain. The UHF signal is attenuated or absorbed by foliage, rough terrain and trees. VHF does better outdoors. VHF has difficulties penetrating steel and concrete. UHF does better in and around buildings. If you use the radios in both environments, we prefer using UHF.

How much power do I need?

Power is a major factor in achieving the range and coverage of a particular structure as well as providing a clear, crisp signal that is easy to understand. Coverage is improved as power is increased.

How many channels do I need?

1 channel per work group is typical. Use multi-channel radios when communicating with other workgroups. Examples: managers, shipping, manufacturing, maintenance, contractors, security, other departments, etc.

“Talk range may very depending on terrain and conditions.” Explain?

Two radios may or may not communicate with each other if either radio is placed poorly or if obstructions have intruded the area. Optimum range conditions are achieved when both radios are at least 5 feet off the ground, antennas are pointing upward, there are zero obstructions, and the radios are facing each other.

The following are examples that may shorten range.

  • Vehicle(s)
  • Radio near body or in pocket
  • Trees/foliage
  • Placement in or around buildings
  • Sitting or squatting

What is “Channel Interference?”

This occurs when more than one party is trying to broadcast on the same frequency. You will hear a pause or break during communications. Some confuse it with short range. Press the “Monitor” button and listen. If you hear someone else, then they are also communicating on your frequency. We suggest changing the frequency. Monitoring the frequency can help when selecting a frequency to use. Channel Interference occurs often in congested areas.

What is a repeater?

Applications covering more than 300,000 sq. ft. will require a repeater. A repeater is a system that is installed to amplify the signal further than the normal radio signal. There is often a monthly fee per radio to use a repeater.

What is an Interference Eliminator Code

Interference Eliminator Codes prevent hearing other nearby businessess operating on the same channel. This promotes workgroup efficiency as your group is not interrupted hearing these other users. Business two-way radios are set to the same frequency and code setting that will communicate with each other. There are 121 codes available on the CLS Series; 219 codes available on the RM, RDX and CLP Series. Codes are easily changed by the user.
