Battery care and maintenance tips –
• The speaker battery will last approximately 2 years depending on usage.
• When not in use, leave speaker plugged into wall outlet with power switch in
‘off’ position.
• Keep speaker away from heating units – use/store in a cool dry place.
• When using speaker battery power (unplugged from wall), always remember to return
power switch to ‘off’ position after use.
• Never mount/use speaker horizontally or upside down. Controls should be accessible
from top of unit.
• Plan on buying new NiMH batteries for your transmitter every 12 months. Alkaline
batteries can also be used as back-ups, however, the 923C charger will not recharge
alkaline batteries. Never attempt to recharge alkaline batteries – this will cause damage
to the unit and void the product warranty.
• Remember to charge all batteries overnight before initial use.
