DWZ-M70 DWZ-B70HL
Two RF Modes for Reliable Transmission
The DWZ-M70 package and DWZ-B70HL package
provide two selectable RF modes. Simply choose
the one that makes best use of your actual 2.4-GHz
RF environment.
[ Wide Band Hopping Mode ]
This mode reduces interference with other wireless
equipment used in the same environment, such as
wi-fi devices. It doesn't require you to have technical
knowledge about radio frequencies.

[ Narrow Band Hopping Mode ]
This mode helps you to avoid interference from other
devices – for example, 2.4 - GHz wireless remote
controllers that are commonly used for lighting control.
This enables you to coordinate frequencies when
using multiple wireless systems simultaneously**.

DWZ-M70 DWZ-B70HL
Stable Transmission
Interruptions in reception (signal dropout) can be
a problem with wireless microphone transmission
systems. With the DWZ Series, however, the
occurrence of signal dropout can be reduced to
a minimum. Utilizing a space diversity reception
system, this series achieves stable reception by using
dual antenna inputs/reception circuits. These receive
signals over two different paths and automatically
select the stronger RF signal for output.
DWZ-M70 DWZ-B70HL
Highly Secure Transmission
These two DWZ Series packages both offer 128-bit
standard encryption technology to secure
transmitted signals and avoid being intercepted
by others. By using this encryption feature, users
c a n r e d u c e t h e w o r r y t h a t c o n f i d e n t i a l
i n f o r m a tion could be intercepted.

Battery Recharging System
The BC-DWZ1 optional battery charger enables
you to recharge NiHM batteries in the ZTX-M02RC
and the ZTX-B02RC. The BC-DWZ1 is a contactless
recharger; this means that you simply place the
handheld microphone and/or bodypack transmitter
into the charging station to
recharge NiMH-type batteries.
You do not need to physically
remove the rechargeable
batteries to recharge them, which
saves you time and reduces
wear and tear to the transmitters.
*BC-DWZ1 and NiMH battery are sold separately.

Robust Metal Body
The ZTX-M02RC handheld microphone (supplied
with the DWZ-M70 package) and the ZTX-B02RC
bodypack transmitter (supplied with the DWZ-B70HL
package) are made of strong durable metal. Metal
construction supports reliable use in rough
operating conditions.
