GWD 910 / 915 Wireless Microphone System Owner’s Manual 7System Overview Wireless Microphone GWD915T/910T 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** GWD 910 / 915 Wireless Microphone System Owner’s Manual 8System Overview APL (Auto Police Location) Body GPS Wireless Microphone / GWD915T  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.
GWD 910 / 915 Wireless Microphone System Owner’s Manual 9Operating Procedure 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. 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. Press the ON or Panic Button once on the wireless microphone for recording. b. Activate video recording at the IN-CAR VIDEO SYSTEM. This action will automatically trigger wireless microphone recording. c. 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. 8. For charging, simply place the wireless microphone to the charger and leave it charging for at lease 6 (six) to maximize battery capacity.
