Customizing the MC 218 204
Battery Type
The Ericsson MC 218 is powered by:
• two AA size 1.5-volt batteries (supplied) – alkaline batteries are
recommended.
• one Lithium 3-volt CR2032 backup battery (supplied). This preserves your
information while you change the main batteries.
Note! You will lose information if you remove both sets of batteries at the
same time, or allow both sets of batteries to become completely run down. The
MC 218 warns you when its batteries are getting low, in plenty of time to
change them.
You can use AA-sized rechargeable Nickel Metal Hydride (NiMH) batteries
to power the MC 218, but some care is required.
If you use rechargeable batteries:
• you are advised to keep two sets of rechargeable batteries: when the pair in
the MC 218 needs recharging, swap them over. If you have just one pair,
you will run down the backup battery while you are recharging them.
• you should replace them with fresh non-rechargeable, preferably alkaline
batteries, if you are not going to use the MC 218 for a while.
Note! When rechargeable batteries go flat, they do so very quickly, and you
may get very little advance warning. The backup battery preserves your
information for a limited time.
You can also run the MC 218 from the mains. You should use only Ericsson
approved mains adapters. See your Ericsson dealer for more information.
Battery Status
To show battery status:
• In Desktop, choose Battery on the Information menu.
The displayed dialog box shows how much power there is in the main and
backup batteries, what power source is used, and usage information.
You can prolong the life of the batteries by considering the following:
• Set the automatic switch off time to a lower value (Switch on/off icon in
the Control panel).
• Use the Backlight sparingly and set its automatic switch off time to a
lower value (Screen icon in the Control panel).
• Set the Link value to Off when you are not using cable link or infrared link
(select Remote Link on the Too ls menu in Desktop).
Switch Off
You can adjust the way your MC 218 switches on and off.
To adjust the Switch on/off settings:
1. In Desktop, tap Control panel on the toolbar.
2. Tap the Switch on/off icon twice and make your selection.
