    Advances in audio quality for loud environments and rough and tumble durability make the Motorola RDU 2020 two-way radio an excellent choice for the demands of your busy enterprise.

    30% louder than prior models; Motorola adds power to the RDU2020’s speakers by bumping them up to 2000 milli-watts (from 500) ensuring that messages are received on every job site. Long a trusted brand in audio engineering, Motorola worked their magic on the RDU2020’s speakers to reduce magnetic field interference, enhance noise reduction and tweak RF specifications for greater clarity. The difference is clear when you’re in a crowded convention hall, a loud factory environment or busy construction site: you’re getting things done.

    Your walkie-talkie’s not going to break on those jobs either. Motorola wasn’t playin’ around when they put in a durable metal-die cast chassis and encased it in a shock absorbent polycarbonate housing. The RDU2020 is rated IP54/55 and to military specifications 810 C, D, E, F for blowing rain and dust, shock, salt fog, vibration and at temperatures as extreme as -22F and 140F: you’ll give out before your two-way radio does.

    What’s easygoing is the usability. The Tri-color LED user interface shows you exactly what’s happening with your radio at a glance. Cloning settings is a snap – pretty much literally – of an (optional) cloning cable. And programming your RDU2020 is easily DIY using your PC, an (optional) Customer Programming Software cable and the CPS software** available free for download for your Windows machine.

    The CPS software** allows you to access all kinds of business friendly features such as Reverse Burst (eliminates noise), Radio Reporting for management of radio profiles and cloning, PL/DL defeat, Manager Lock, Power Select (in increments of .5-Watts, saves battery) and two Time-out Timers.

    General RDU2020 radio features include: auto-scan, radio mic gain, accessory mic gain, scan and scan list, battery save and low battery indication.

    The Motorola RDU 2020 offers a flexible battery and charger options. The standard issue RLN6352 Lithium Ion battery lasts up to 12 hours on a single charge. If you need longer battery life at a clip, you can upgrade to the RLN 6308 Ultra High Capacity Li-ion battery which holds a charge for up to 26 hours when used with the 2-Watt RDU2020 radio. A drop-in charging tray and wall adapter arrive in the box when you order your RDU2020 2-way radio. However, if you want to charge and clone settings for multiple radios at a time, Techwholesale offers a 6-unit multi-charger at a great price. Bonus bit – your walkie-talkies cease to go walkabout when they’re all stored in one centrally located charger next to the manager’s desk. To ramp up in a hurry, get the 2-hour rapid charger kit for quicker turnaround.

    Who should use the RDU2020 2-way Radio? Anyone, but certainly businesses in need of a high performance, heavy duty walkie-talkie.

    Vet Clinics: Animals can be a handful especially when they're sick, scared or both. Reception can radio to the kennels when they're ready to go in or out. Doctors can call techs when they need another pair of hands. Communication from the front to the back of a vet practice is a huge time and energy saver for all involved. The RDU2020 offers a simple, solid solution to handling animals in a well-controlled environment.

    Grocery Stores: Customers aren’t patient when they’re waiting in line for a price check; neither are the folks behind them who don’t care about the price of tea in Chicago. Perishable items will just go ahead and … perish, while they’re waiting for managers to mobilize a team to unload the truck. The right two-way radio can fix all that.

    Conventions: From Klingons to Cardiologists, a quick response to attendee issues means the convention comes back again next year. Make sure everything runs smoothly at your next convention using a Motorola RDU2020 handheld radio. (Sorry, we don’t carry Star Trek communicators).

    Retailers: When the price is right all around the store, and products are flying off the shelves, or no one’s sure what the price is or if you’ll match Acme’s online price, let your 2-way radio do the walkin’.

    Restaurants: Yelp, Chowhound, Urbanspoon, Zagats! Forget Big Brother -- the whole world’s watching. Make sure your diners get a table and get their food quick and to their liking, so your restaurant gets a 4 star review. Motorola can help.

    Medical Offices: Bouncing from billing to the back office to the waiting room back and forth all day long is going to land your staff at the shrink due to stress. Save steps, time and nerves with walkie-talkie communication. Light and easy to use, the RDU2020 is just what the doctor should order.

    *Coverage will vary based on terrain, conditions and the radio model used. ** CPS is available as free download. Windows(r) XP, Windows 2000 compatible, separate USB cable required.
