BACKUP BATTERY

Your transceiver uses a lithium battery to keep stored options in memory
when you disconnect the transceiver from a power source. This battery
should last 3 to 5 years, under normal conditions. When the transceiver
frequently displays ER1, the back up battery needs to be replaced.
NOTE: To clear the error, reset the transceiver. See "Resetting the
Transceiver."
The backup battery is not user-serviceable. Take the transceiver to your
local Radio Shack store to have the battery replaced by a Radio Shack
repair center.
This product contains a rechargeable nickel-cadmium (lead acid) battery.
At the end of the battery's useful life, it must be recycled or disposed of
properly. Contact your local, county, or state hazardous waste management
authorities for information on recycling or disposal programs in your area.
Some options that might be available are: Municipal curb-side collection,
drop-off boxes at retailers, recycling collection centers, and mail back
