Battery Backup
We recommend that you also install a 9–volt alkaline battery as a backup
power supply. In the event of a power outage, the battery will power the con-
sole. Not only will this prevent the loss of data stored by the console, it will
allow you to continue observing weather conditions during the power outage.
New alkaline batteries will power the console for 24–48 hours. For maximum
security, keep the battery backup fresh. You should replace batteries any time
the unit has operated on battery power for more than 18 hours. To prevent loss
of data when replacing batteries, make sure the unit is receiving power from
the adapter before changing batteries.
Note: The use of Ni-Cad batteries is not recommended. Ni-Cad batteries carry less power than alka-
line batteries and they will not be recharged by the console. In the event of a power outage, Ni-
Cad batteries will be able to power the console for a shorter period of time than alkaline batter-
ies will.
To install the backup battery, remove the battery cover underneath the console,
snap the battery connector onto the battery, lower the battery into the compart-
ment, and replace the battery cover.
