Avoid excessive heat: Do not leave transmitters or portable PA receiver in direct sun for extended periods, in front
of heaters or any source of high temperature.
Avoid rough handling: Transmitter or portable PA receiver may be damaged if dropped.
Fully charge portable PA battery: Ensure battery is fully charged before placing into storage for long periods.
Ensure battery is charged once per month thereafter to ensure long life and optimum battery reliability.
Remove batteries: Remove batteries from transmitters when not in use.
Replace batteries: Ensure replacement batteries are the same or equivalent to existing. Batteries may explode
under charge or unit may malfunction if incorrect batteries are used.
Battery terminals: Ensure battery contacts are clean and free of corrosion before operation. If corrosion occurs it
