6. ABOUT THE POWER SOURCE
The WA-1822(C) Meeting Amplifier is designed to operate on both AC power supply and standard dry
batteries.
6.1. Using AC Power Supply
Remove the power cord from the component compartment, and connect to an AC outlet. Always be sure the
unit's power is switched OFF before connecting or disconnecting the power cord.
Notes
• Approximately 1 W is continually consumed even if the power switch is set to the OFF position.
• When the unit is not used, remove the power cord from the AC outlet.
6.2. Using Batteries
6.2.1. Battery type
Eight R20P ("D" cell) batteries of manganese or alkaline types can be installed in the battery case.
6.2.2. Battery installation
Step 1. Be sure to turn the power switch OFF and detach the power cord from the AC outlet.
Step 2. Remove the compartment cover, then pull the battery case out of the compartment.
The battery case can be easily removed by lifting slightly first before sliding it out of the compartment.
Step 3. Place 8 batteries in the case, noting the correct polarities indicated inside the case, then reinsert it in
the battery compartment.

6.2.3. Power supply switching
Detaching the power cord from the AC outlet automatically switches the power source from AC to the battery.
6.2.4. Guidelines on battery replacement times
• A dimming power indicator indicates that the batteries are beginning to lose their charge and should be
replaced as early as possible.
• Intermittent sound output may occur even when the power indicator remains steadily lit. It is recommended
that the batteries be replaced as early as possible in this case, too.
• Approximate battery usage times (replacement times) are shown below.
[When using the WA-1822 at room temperatures of 25°C]
Manganese batteries: Approximately 12 hours (continuous use)
Alkaline batteries:
Approximately 24 hours (continuous use)
[When using the WA-1822C at room temperatures of 25°C]
Manganese batteries: Approximately 6 hours (continuous use)
Alkaline batteries:
Approximately 12 hours (continuous use)
Notes
• Avoid mixing manganese and alkaline batteries.
• When changing batteries, always replace all 8 batteries at the same time. Combined use of new and old
batteries may cause battery leakage.
• Remove the batteries when not in use for prolonged periods of time (10 days or more).
