before switching the microphone off automatically.
8. To turn the microphone off press the power switch for 2-3 seconds until the LCD screen displays "OFF"
9. When using with rechargeable NiMH batteries, connect a DC 5V plugpack (Altronics M 8909 or M 8909A plus
M 9187 tip adaptor) to the charging port on the base of the microphone. 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 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. Note: microphone is unable to be used during charging process.
Troubleshooting
• Power LED does not illuminate after pressing power switch
Check batteries are charged and inserted correctly.
When pressing power switch ensure you hold it down for 2-3 seconds
• LCD shows "Err" when switching off
Contact your place of purchase for information on resetting your microphone.
• LCD panel displays garbled information
Remove batteries and re-insert them
• No sound output
Check frequency of transmitter is the same as the portable PA receiver
Check volume level of both transmitter and portable PA receiver
Ensure microphone is within range of the receiver
Check for sources of interference, large metal objects etc within range of the microphone
• 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.
