The backlight and sound are automatically
turned off when the low battery indicator is
displayed. Any alarms set prior to the
appearance of the low battery indicator will
remain active.
To change the battery:
1.
Open the battery cover with a coin by turning it
from CLOSE to OPEN.
2.
Remove the battery cover and lift the battery
(CR2025) out carefully with a suitably sized
small rigid stick or bar. This can be a toothpick
or small screwdriver. However, a non-metal tool
is preferable. Be careful not to damage the
metal sound element (*) or the grooves.
3.
Insert a new battery with the positive (+) side
outwards.
4.
Replace the old sealing ring with a new one,
fitting it snugly in the cover groove to ensure
water resistance.
5.
Put the cover back on and turn it clockwise to
CLOSE.
6.
Re-enter the basic settings. For further
information, see Basic Settings.
