9. When using with rechargeable NiMH batteries, connect a DC 5V plugpack (Altronics M 8909A plus M 9187 tip

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 batteries 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.
