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 850iR 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
850iR. 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.
