In the event of a battery change or power
failure, the memory retains all values mea-
sured; the date and time must, however, be
reset. This is indicated by the year indicator
flashing.
For changing the batteries and resetting the date/
time please follow the instructions in Section 1 on
page 6.
Which batteries and which procedure?
Please use 4 new, long-life 1.5 V, size AA
alkaline batteries.
Do not use batteries beyond their date of
expiry.
If the monitor is not going to be used for a
prolonged period of time, the batteries must
be removed.
Using rechargeable batteries
You can also operate this monitor with recharge-
able batteries.
O nly use «NiMH» type reusable batteries.
W hen the flat battery symbol appears,
remove the batteries and recharge them.
They must not remain in the monitor as they
may become destroyed (exhaustive discharge
due to low consumption of the monitor even
when switched off).
