Change the Battery on the Motherboard
To avoid damage to equipment or injury to personnel, read this procedure completely before
beginning work. Be sure to observe all cautions and warnings.
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory when the XD20 is
disconnected from AC power. The battery has an estimated life of two years. When the XD20 is
connected to AC power, the standby current from the power supply extends the life of the battery.
This battery is not necessary for proper playback of audio, and has no effect on playback. The battery
enables the XD20 to maintain accurate date and time settings. Replace the battery on the ASUS
motherboard with one of the following approved batteries:
Newsum CR2032
Duracell DL2032
Sony CR2032
Hitachi LTD CR2032
Instructions
Please note that the motherboard model can change without notice so the instructions and location
shown for the battery may change.
Caution
: Risk of explosion if the battery is replaced with an incorrect type. Batteries should
be recycled where possible. Disposal of used batteries must comply with local environmental
regulations.
Follow these steps to replace the battery.
1.
Turn off the XD20 and disconnect the power cord from the AC power source.
Note
: It may be necessary to disconnect all cabling and take the XD20 to a workbench to
perform this procedure. In that case, record the cabling connections so they can be
reconnected later.
Caution
: Wear an anti-static wrist strap to prevent electro-static damage to
the XD20.
2.
Remove the cover of the XD20.
