Battery Installation
Install the included 9V size battery in the unit.
If the battery power is low or the battery is not installed, “Lo” flashes.
Replace with a new one. (If “Lo” flashes after installing a new battery, it will
disappear after 10 seconds. Simply disconnect the AC adaptor cord and
reinsert it again without removing the battery.)
The new battery’s retention time is approximately 1 day for recorded
messages and the clock {p. 10) during a power failure.
