Scrambler PLUS wireless provide crystal clear voice communication across a multitude of industries.
All Scrambler Plus intercoms operate in simplex mode, which means that when one person in a group transmits the message is received by everyone.

An unlimited number of transceivers can operate on the same frequency, and a simple rotary dial allows users to switch channels instantly.

Scrambler PLUS two-way radios feature 500 Mw of punch out transmitting power that can penetrate concrete or steel with a range of up to 1 mile. Operating in the non-licensed FRS band with 14 frequencies installed.

Scrambler Plus systems can be used immediately, right out of the box. This makes the Scrambler Plus Series an affordable sound solution to businesses, schools, and churches as well as any on location venue where users need to communicate between buildings or through walls.

With the Scrambler Plus you never have to worry about interference or someone outside your group listening to your conversations. In order for an RF signal to be received it must be accompanied by one of 38 privacy tones programmed into all the radios in your system. In addition, outgoing transmissions are encrypted eliminating the possibility of eavesdropping. This means that both outgoing and incoming wireless signals are guaranteed to be totally private.

EARTEC offers a full line of headset styles all the way from discreet lightweight to heavy duty industrial models. This allow you to pick the best headset and customize the Scrambler Plus to meet your needs.

Operation of The Scrambler is as easy as turning the radios on, setting the channel, and connecting the headsets. To transmit press the button installed inline on the headset wire and the message will be received by all radios that are tuned to the same frequency.

There are only two simple dials that govern the function of the entire system, an On-OFF Volume control and a channel knob. A technique known as “voice annunciation” actually calls out the channel number thru the headset speakers so users know which frequency is being monitored without having to look at the radio.

Scrambler Plus include powerful Lithium Polymer batteries. These high capacity rechargeables will not develop a memory so they do not have to be drained after use. To charge the batteries place the radios into the desktop charging base (included). A Red LED indicates the battery is charging, Green LED shows that the battery is ready to go. Battery life on a full charge is approximately 8 hours.

All complete Scrambler UHF systems also include a foam filled hard plastic case for safe storage and transport.
