With the latest technologies, the GWD900T is able to synchronize the frequency of any GWD900T Handset with any GWD900R Base Station. Just follow these few simple instructions to ensure maximum performance:
1. Check out any GWD900T handset and make sure it is fully charged before operation. 2. Please be sure the System is ON before proceeds any further. 3. Slide the Handset contact directly on top of the Base Station register contact until a confirmation tone has sound. This indicates the register contact has synchronized the frequency of the Base Station and the Handset is now on standby 11 Operating Procedure mode and is ready for use. 4. Please only synchronize one Handset to one Base Station. 5. There are two 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 System This action will automatically trigger wireless microphone recording. 6. To prevent accidental audio shut off. The only way to return Handset to standby mode from recording mode is to stop the video recording from the System. 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 Base Station or reposition the Handset until the warning stops. However, if the warning persists and exceeds 30 seconds, the Handset will automatically shut off and return to standby mode. If user returns within the signal range again while the video is still recording, the Base Station will re-initiate the wireless microphone automatically. 8. For charging, simply place the wireless microphone to the charger (GWDCHG01) and leave it charging for at lease 6 (six) to maximize battery capacity. 12 GWD 900 Series Wireless Microphone Owners Manual GWD 900 Series Wireless Microphone Owners Manual Federal Communications Commission
