cei007 Charging/Encryption Interface
The cei007 Charging/Encryption Interface has two functions:
The cei007 is a 7-bay charger for SpectraPulse
™
mtu101 Boundary Microphone Transmitters
using the supplied rechargeable AA Nickel Metal Hydride (NiMH) batteries. It is able to charge
up to seven mtu101 units (14 AA NiMH batteries) either separately or together in about 6 hours.
LEDs show charging status at all times.
The upper-most bay of the cei007 also functions as an encryption station for SpectraPulse
™
mtu101 Boundary Microphone Transmitters (in conjunction with optional SpectraPulse
™
System
Encryption Software – available separately-see page 14). SpectraPulse
™
encryption meets NIST-
approved AES 128-bit encryption standard developed by the U.S. government for securing
sensitive material. (See the SpectraPulse
™
sep128 Encryption Manual for instructions on how to
encrypt the SpectraPulse
™
UWB wireless microphone system.)
How to use the cei007 as a recharging station
1. Plug the DC cable from the included wall-adapter power supply into the rear of the cei007
unit; plug the other end of the power cord into a standard wall outlet. (See
cei007 Power
Cord
, page 14.)
2. Turn the cei007 unit on. (See
cei007 On/Off Switch
, page 14.) All LEDs will illuminate for
approximately 2 seconds.
3. Make certain that the mtu101 Boundary Microphone Transmitters you will be recharging are
equipped with rechargeable AA NiMH batteries (included with cei007 unit) that are correctly
installed.
WARNING: Do not use the cei007 Charging/Encryption Interface to charge
batteries of other types besides NiMH or damage may result. If an mtu101 with alkaline
batteries is inserted for charging, the green and red LEDs will flash simultaneously as a
warning.
(See
mtu101 Battery Installation
, page 13.)
4. Turn the mtu101 Boundary Microphone Transmitters
off
. (If the mtu101 units are on, they will
not recharge properly and the green and red LEDs will flash simultaneously as a warning.)
(See
mtu101 Power On/Off
, page 13.)
5. Place mtu101 units in charging bays as illustrated at right.
6. Confirm that the red Charging LEDs (on the cei007) are illuminated.
7. When green Full-Charge LEDs (on the cei007) come on, the batteries are fully charged and
ready for use. You may use them immediately, or leave the mtu101 units in the recharging
station until next needed.
Note: The charger does not use a “trickle charge” current to maintain full battery. If you
leave fully charged mtu101 units in the charger for a long period, some of the charge
may be depleted. In this case (to ensure that the batteries are completely charged for
maximum operating time), turn the cei007 unit off and on again and wait until the
green Full-Charge LEDs are again illuminated before removing the microphones from
the charging bays.
