Question about Sharp AR-M237 Copier
THe battery on your fax board is below 2.90 volts you can replace the battery.

This is not "from a defective fax board"
98% of the time it is the Battery on the Fax Board..
Usually turning off your machine will make this go away,
Sometimes preventing your machine from going into Sleep Mode also helps.
The Fax Battery is much like the CMOS battery in a computer.
A large round thin battery, (much like a watch battery)
To replace this, the fax board has to be removed, The battery is Soldered to the Board, you have to unsolder the battery, then solder the new battery to the fax board, then reinstall fax board, then set jumpers on fax board. Turn machine on, do some settings, turn machine off, remove jumper from fax board. Then restart, hopefully you will not have to reset the county code.
Unless your experienced with this, do yourself a favor and call a tech..
