Signal disturbance
When operating two transmitters in the same area, ensure frequencies selected are several channels apart. This
helps to reduce crosstalk between transmitters. Also note that other wireless devices can cause interference,
ensure you adjust your frequency around these devices where possible.
1. Ensure microphone is switched off before inserting batteries.
5.The LCD screen will display the channel selected. To determine which frequency this channel is operating on, press
the UP or DOWN frequency adjustment buttons.
6.Press the frequency set button for 1-2 seconds. The LCD screen will flash the currently selected channel number.
You can cycle through the channels by pressing the UP or DOWN frequency adjustment buttons. Press the frequency
set button again to lock in your channel selection.
7.The battery status is displayed on the left of the screen. When battery capacity is critical, the icon will flash 3 times
before switching the microphone off automatically.
8.When using with rechargeable NiMH batteries, you can use the HDC-809 charging pod. This allows you to put up to
2 bodypacks on charge at the same time. Charging time is dependant on the capacity of batteries used, typically 10-12
hours charging is required. If battery icon is flashing when charger is connected, ensure rechargeable batteries are
inserted in the microphone. If batteryies have failed both the battery icon and screen backlight will flash.
During normal charging the battery icon will cycle through the charge "block" icons. Once full capacity is reached the
full battery icon and all "blocks" will be displayed.
2. Remove battery clip. Insert 2 x AA batteries (alkaline or rechargeable's are recommended).
3.Switch the top mounted power switch to ON. The power LED will illuminate red and "ON" will be displayed on the
LCD screen.
4. A selection switch on the side of the bodypack provides three level settings (low, mid & high) depending on the
application or environment in which the portable PA is to be used. The mute button allows bodypack to be put on
standby without switching the power off.
