Battery Selection and Installation
The GWD915/910 wireless microphone is
powered by a rechargeable lithium-ion battery.
The wireless microphone housing is designed to
prevent incorrect installation of the battery. Do not
force the battery in to the housing. Reversed
batteries may cause damage to the wireless
microphone. The battery compartment is located
at the bottom of the wireless microphone. Slide off
the battery cover and remove the silicon seal, at
this point the battery is free to slide out.
Transmitting Antenna
The GWD915/910 Wireless Microphone includes a
flexible antenna, which is package separately to
prevent damage. Remove the antenna from the
package and tighten the antenna to the wireless
microphone. For best result, allow the antenna to
extent fully. If the signal is marginal, please
experiment with different wireless microphone
position on your body. Do not attempt to remove,
replace or change the length of the transmitting
antenna, which might result in damage of the
audio system and may violate FCC regulation
Wireless Microphone Contact
The wireless microphone contact is used to
synchronize the frequency of the wireless
microphone and the receiver. It is also the contact
for the battery charger.
„
„
Microphone special function note:
„
Special OOR Mode: Turn OFF Buzzer and Vibrate Alter to avoid the police become
shooting target when he chasing suspects and running out of
radio range (OOR) -- (Use Control command)
Suspend Enable: When microphone out of radio range or police off duty over 3
hours, Microphone goes into suspend to save Battery Power.
Suspend wake up: 1. Press microphone REC Button (Big) direct to On Air (Record).
2. To sync with Receiver or contact the charger again.
OAD (Over Air Download Program): Auto overwrites Mic. compatible firmware when
sync with incompatible Receiver. (All LED blinking around
60Sec then Beep 3 times to finish OAD process)
** During OAD can’t move out battery or to sync, but it can press REC Button**
APL (Automatic Police Location) Function: The Body GPS Mic. can send police real
time location and body motion (walking, running, lying) from 2,000~3,000 feet to patrol
car and PD when police in emergency or chasing suspects.
The PD can use dispatch or mapping system share the location coordinates and
body motion to other patrol car for quickly support and rescue.
When police walking out of patrol hit or attacked by car or suspect, also police
suddenly running to chase suspect, the Body GPS microphone can auto trigger
recording and send back location to PD for quickly support and rescue.
GPS Location Data Output Rule and Power Mode:
1. When Police moving over 10M (30 feet) - output one coordinate.
2. Moving in 10M (30 feet) - Every 1 minute output one coordinate.
Continue Power Mode: Continue tracking satellites after 3D fixed (High Accuracy)
Saving Power Mode: Every time GPS 3D fixed, the GPS go to sleep for 10 seconds
then wake up for satellites acquisition until the GPS 3D fixed again.

Operating Procedure
Federal Communications Commission (FCC) Statement
The GWD915/910 is designed to eliminate unnecessary hassle of pairing a receiver with a
particular wireless microphone. With the latest technologies, the GWD915/910 is able to
synchronize the frequency of any GWD915T/910T Wireless Microphone with any
GWD915R/910R Receiver.
You are cautioned that changes or modifications not expressly
approved by the part responsible for compliance could void the
user’s authority to operate the equipment.
Just follow these few simple instructions to ensure maximum performance:
1.
Check out any GWD910T Wireless Microphone and make sure it is fully charged
before operation.
2.
Please be sure the IN-CAR VIDEO SYSTEM is ON before proceeds any further.
3.
Slide the wireless microphone
contact directly on top of the
receiver’s register contact (located on
the top of the IN-CAR VIDEO
SYSTEM monitor module) until a
confirmation tone has sound. This
indicates the receiver’s register
contact has synchronized the
frequency of the receiver and the
wireless microphone. Wireless
microphone is now on standby mode
and is ready for use.
4.
Please only synchronize one wireless microphone to one receiver.
5.
There are three methods to activate recording on the wireless microphone:
a.
b.
c.
Press the ON or Panic Button once on the wireless microphone for
recording.
Activate video recording at the IN-CAR VIDEO SYSTEM. This action
will automatically trigger wireless microphone recording.
Turn on the light bar or siren in the patrol car. This action will also
automatically trigger wireless microphone and video recording.
6.
To prevent accidental audio shut off. The only way to return wireless
microphone to standby mode from recording mode is to stop the video recording
from the IN-CAR VIDEO SYSTEM. Or press and hold PB2 until 3Seconds.
7.
During recording mode, if the warning sounds and the yellow LED flash, this
means the signal is marginal or weak. At this time, please step closer to the
receiver or reposition the wireless microphone until the warning stops. However,
if the warning persists and exceeds 30 seconds, the wireless microphone will
automatically shut off and return to standby mode. If user returns within the
signal range again while the video is still recording, the receiver will re-initiate the
wireless microphone automatically.
For charging, simply place the wireless microphone to the charger and leave it
charging for at lease 6 (six) to maximize battery capacity.
8.
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
You are cautioned that changes or modifications not expressly
approved by the party responsible for compliance could void your
authority to operate the equipment. .
