CHARGING THE HM-70 HANDHELD MIC
1. Ensure the HM-70 Handheld
Microphone is turned OFF (ON/OFF
switch on the side of the unit).
The 880iR can be left on, but must
be connected to AC power in order
to charge the microphone.
2. Connect
the loose end of the
charging cable into the jack labeled
CHARGER on the side of the HM-70.
Connect the larger end of the
charging cable to one of the
CHARGERS jacks on the back of the
880iR. The HM-70’s rechargeable
batteries are factory installed.
3. The power
indicator light next to
the power switch glows green when
the cable is connected and charg-
ing correctly. The light goes out
when fully charged. Batteries
will charge in 8 to 12 hours. A fully
charged battery will run for up to 8
hours of continuous operation.
4. The HM-70
can remain charging
for up to 10 days. Overcharging
will shorten battery life.
The HM-70 does not use a cradle for charging.
The charging cable must be plugged directly
into the charging jack in the transmitter.

7. SPEAKER ZONING: These switches
turn the corresponding speaker
(connected to the same numbered
jack on the back of the unit) on
or off.
• Speaker Zoning: By “zoning” or separating the classroom into different areas
where audio may or may not be desired, the teacher has greater flexibility
controllng the dispersion of sound throughout the room. Zoning is especially
useful in large or odd-shaped classrooms
• Speaker Volume Control: An area of the classroom might contain a noise
emitter such as an HVAC system. In this case, it may be necessary to turn up
the volume of the affected speaker to overcome the noise in that area. When
this situation arises, the 880iR allows the user to fine tune the output level
.
