• Low battery shutdown: Automatic shutdown of all DC outputs when the battery
voltage is 9.1V ±4%. Remaining load on the battery is less than 5 mA.
When the remote On/Off switch is enabled and the AC input is not available, power is
delivered regardless of the charge on the battery as long as battery voltage is greater
than the low battery shutdown voltage. This insures that the system could be operated
with a battery that is not fully charged.
• Enable after shutdown: If the AC input is not available after battery replacement,
power is delivered when the remote On/Off switch is enabled as long as the battery
voltage is 9.9V minimum.
