4 Operating Notes
• If reception on the selected carrier frequency is poor, use automatic Frequency Selec-
tion ("FREQ" -> "AUTO" -> "CHANNEL") on the receiver to find the nearest clean Chan-
nel within the selected Frequency Group.
• Should you find no clean Channel, use automatic Frequency Selection ("FREQ" ->
"AUTO" -> "GROUP") on the receiver to select a different Frequency Group within the
same Preset and selecet a new frequency for each transmiter and receiver.
1. If you know you won't be using the transmitter fo more than a week, remove the bat-
teries or BP 4000 battery pack from the transmitter.
2. Make it a habit to charge the BP 4000 battery pack fully every time you used the trans-
mitter for at least one or two hours. This is a good way to prevent the battery pack from
dying in the middle of the next gig.
3. Always charge the BP 4000 battery pack fully before storing it outside the transmitter.
This will maintain the battery pack's capacity at a higher level for a longer time.

5 Cleaning

• To clean the transmitter surfaces, use a soft cloth moistened with water.
