This may be shown on the screen as
‘ER20’
or
‘BATT’
. Whenever the Deafgard
performs a self test routine (every 7 days or on demand) the battery pack voltages
are checked. If the batteries voltage drops to or below 1.87 volts, it is deemed to be
flat, and an error message will be shown on the screen.
Resolution:
Replace all 4 batteries with new “C” size batteries.
