High Transmission Reliability

• Only approved for radio applications with a "Very Low Duty Cycle < 0.1 %". Transmissions on FM 868.8 MHz frequency must be short which means that "Long-term transmitters" such as radio headphones or baby monitors are not allowed on this frequency, preventing noise  
• Frequency Modulation (FM) further increases the transmission reliability
• Generally, no visible antennas are necessary to gain signal strength 
• Excellent selectivity; the receiver can clearly distinguish "its own" transmitter's radio signal from other radio signals, and receives the signal reliably.

Extremely safe Somloq Rollingcode system

• Safe from "code scanning" (a code length of 66 bits gives 74 trillion possible combinations. Scanning would take approx. 234 billion years)
• Safe from "code grabbing" (bug-proof)
• The code changes every time it is activated (Somloq Rollingcode system). Transmitting a recorded code would therefore be ineffective
• Safe from use by unauthorised persons

Durable

• Only high-quality components are used
• Consistently high quality, even over a long service life (for example, fluctuations in temperature or vibrations have no effect)

Many applications

Whether for indoor or outdoor use, SOMMER radio technology is ideal for a wide range of applications, such as:

• All types of operators (e.g. for garage, swing and sliding doors/gates)
• Door openers
• Roller shutters and blinds
• Lighting (indoor and outdoor)
• Alarm systems
• Fountains
• and many more.

An extra bonus: its simple, fast and economical installation. No laborious and expensive laying of cables required – saving time and money!

Low energy consumption

• Thanks to the antenna's superior efficiency, longer battery life (standard, flat lithium button cell CR 2032) at same range (approx. 50 m, depending on surroundings).

Definite identification of the transmitter - teach-in via radio

• Each transmitter has its own, unique serial number
• Each receiver can store 112 different codes; each button of the transmitter has its own code
• Because each transmitter has a unique serial number, an individual transmitter code can be deleted on the receiver without affecting other transmitters.
