IV.CHARGING THE BATTERIES
When there are good batteries in the COMMUNICATOR®and the power is on, the red
light above the power (PWR) button will be lit. This light only indicates the power is on.
It does not indicate how much power is left in the batteries. As the batteries weaken during
routine use, you will hear a repeating beep in the earpiece, indicating the batteries need
to be replaced. When this happens, remove both batteries from the Communicator as
shown in Figure 5. Place both batteries in the AC900 Battery Charger for recharging.
Refer to Figures 6 through 8. Replace the batteries in the Communicator with fresh, fully
charged batteries. Typical battery life with normal use is 8 to 10 hours.
CAUTION: To prevent damage, turn Communicator OFF before removing or install-
ing batteries !
Figure 5. Remove and replace Communicator battery
Use the AC900 Battery Charger as follows:
Place up to four batteries in the charger for charging at a time, as shown in Figure 6. The
red Charging light, adjacent to a battery being charged will go on and remain on while
the battery is charging. Routine battery charging takes up to 3 hours.
NOTE: The COM400CC uses “smart batteries.”
That means each battery maintains a history of
the number of times it has been charged. The
AC900 Battery Charger reads and updates this
history each time a battery is charged. This infor-
mation is used to automatically initiate conditioning
cycles, which improve the battery’s performance
and prolong its life. A conditioning cycle consists
of a complete discharge before a battery is
charged. This happens each time the battery his-
tory indicates it has been charged 10 times since
the last conditioning cycle. While a battery is
discharging, the red Charging light next to it will
blink on and off at 2-second intervals. The condi-
tioning cycle takes up to 6 hours.
Refer to Diagnostic Light Table on page 6 for
other Charging light functions.
Figure 6. Inserting a battery into the
AC900 battery charger

Battery charging takes approximately 2 hours
and 20 minutes. When a battery is fully
charged and ready for use, its red light will go
off and the green Ready light next to it will go
on. Refer to Figure 7.
To remove a fully charged battery from the bat-
tery charger, press down on the battery release
tab next to it, and push the battery from the end
near the status lights.
Store fully charged batteries in the storage ports
on the right side of charger until you need them,
as shown in Figure 8.

Light behavior What it means What to do
Red blinks: 2 times quick - 3 seconds off Discharge error Either the battery or the charger
has a problem. Mark the battery
and retry in a different charging
port. The battery is faulty if it has
the same problem in a different
port AND a known-good battery
passes in the same ports. The
charger circuitry is faulty if a
known-good BATTERY fails in
the same ports.
Red blinks: 3 times quick - 3 seconds off Charging error
Red blinks: 4 times quick - 2 seconds off Low-battery error
Red blinks: 5 times quick - 2 seconds off Charging error
Green blinks: 2 second on - 2 second off Read-write error

V.CARING FOR THE EQUIPMENT
A. Proper Handling of the Headset Cable and Connector
B. Cleaning the Communicator and Battery Contacts
1. The Communicator
The following cleaning procedure is recommended at least once each month.
!Remove the batteries from the Communicator.
!Clean the Communicator with a damp sponge. Wet the sponge and wring
it out so it is damp, not dripping wet. Spray household cleaner on the
sponge, NOT DIRECTLY ON THE EQUIPMENT. Clean the Communicator
with the sponge, and dry it throughly.
!Clean the headset and cable with a damp sponge sprayed with houshold
cleaner. The foam muff on the headset earpiece is easily replaced for
sanitary purposes. To order extra foam muffs, call your local HME sales
representative.
2. The battery contacts
Clean the battery contacts in the COM400CC COMMUNICATOR®and on the
batteries and battery charger monthly as follows:
CAUTION: Always turn the Communicator off and unplug the battery
charger before cleaning them.
Remove all batteries from the Communicator and battery charger. This should
be done when no batteries are being charged in the battery charger. Wet the
tip of a cotton swab with rubbing alcohol, and squeeze the excess alcohol
from the swab. Use the damp swab to wipe the metal contacts on each bat-
tery, and inside the two battery compartments on the Communicator and the
four battery ports on the battery charger. Allow the contacts to dry before
placing batteries back into the Communicator or battery charger.
ALWAYS NEVER
O Align the connector key and pins with key and
holes in the receptacle when plugging the headset
into the Communicator.
O Grasp the connector to plug in or unplug the headset.
O Use both hands to remove the headset from your head.
O Use both hands to adjust the microphone position.
O Handle the headset cable with care.
O Carry and hang the headset by its metal headband.
O Twist the headset connector into the
Communicator receptacle.
O Grasp and pull the cable to unplug headset.
O Remove the headset with only one hand.
O Adjust the microphone position with only one hand.
O Pull, twist, bend or knot the headset cable.
O Carry or hang the headset by its cable.

VII. FCC NOTICE
HME wireless radio frequency systems are type-accepted in the United States under Part
90 of the Federal Communications Commission (FCC) Code of Federal Regulations, and
type-approved in Canada by Industry and Science Canada. Because licensing depends
on the system’s application, it is the user’s responsibility to apply for a license from the
FCC in the U.S. and its possessions, or from Industry and Science Canada in Canada
and its territories. Licensing requirements vary from country to country. Contact your
local licensing agency for specific requirements.
This device complies with Part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) This device
must accept any interference received, including interference that may cause undesired
operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses and can radiate radio fre-
quency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communication. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at his own expense.
Changes or modifications not expressly approved by HM Electronics, Inc. could void the
users authority to operate this equipment.

Before using the COM400CC COMMUNICATOR®, charge all
batteries in the battery charger as described on pages 5 and 6.
2. Check/Set Communicator frequency:
Check the Communicator frequency to be certain it is the same
as the audio system base station frequency. If necessary, set
the Communicator frequency as follows.
!Turn the Communicator off by pressing and holding the
power (PWR) button until the red power light goes off,
then release the button.
!Use a Phillips (crosspoint) screwdriver to remove the
panel covering the Communicator DIP switches as
shown in #1 and 2 of Figure 9.
!Compare the positions of the audio system base station
SW1 frequency selection switches 1 - 8 on the Interface
Circuit Board with the DIP switch settings in Table 1 to
determine the transmit and receive frequencies.
!Check the positions of the Communicator DIP switches
(#3 in Figure 9) to be certain its transmit frequency set-
tings match the receive frequency of the base station,
and its receive frequency settings match the transmit
frequency of the base station. Refer to Table 2 below.
