IMPORTANT BATTERY PRECAUTIONS
The CASSIOPEIA has a dual power supply that consists of a battery pack (or ,main batteries) and back-up batteries. Be sure to load the battery pack (or the main batteries) and back-up batteries before using the CASSIOPEIA. Also, charge the battery pack (or replace batteries) as soon as possible at the first sign of low power. Important! � Use the battery pack or two AA-size alkaline batteries for the main power supply, and a CR2032 lithium battery and a IVR 2430 battery for the back-up power supply. Never use any other type of battery with the CASSIOPEIA. � The rechargeable back-up battery (IVR2430) is charged by power from the main power supply. The rechargeable battery is provided in order to prevent premature discharging of the primary back-up battery (CR2032). Never remove the rechargeable back-up battery. � Never remove both the battery pack (or the main batteries) and the primary back-up battery from the CASSIOPEIA at the same time. If you do, data stored in memory can be corrupted or lost entirely. � Never remove the primary back-up battery from the CASSIOPEIA while the battery pack is full discharged (or the main batteries are dead). If you do, data stored in memory can be corrupted or lost entirely. � Whenever the battery pack (or the main batteries) and the primary back-up battery both require replacement, be sure to replace the battery pack (or the main batteries) first, before replacing the back-up battery. � Be sure to watch out for signs of low battery power. Recharge the battery pack or replace main batteries as soon as possible after the message shown below appears on the display. �Your main batteries are running very low on power. Please change the batteries at your next opportunity.� Replace the primary back-up battery as soon as possible after the message shown below appears. �Your backup battery is very low or missing. Data loss may result from failure to replace the battery very soon.� Failure to replace batteries when they are low can result in corruption or loss of data stored in memory.

Replacing the main batteries
1. Make sure the CASSIOPEIA is turned off. � If the CASSIOPEIA is on, press the power button to turn it off. 2. Close the CASSIOPEIA and turn it over. 3. While holding the battery holder release in the �FREE� position, slide the battery holder from the CASSIOPEIA.

� While holding the battery holder in release position, grasp the center of the battery holder and carefully pull it from the CASSIOPEIA.
