The determination of the day maxima is only restarted after a correct day
termination (normally at 06:00 hrs.). Therefore where applicable, a day maximum
arising on the day of the voltage failure is not taken into account. However, the day
maximum of the current month found before the day of the voltage failure is
correctly restored from the EEPROM.
5.4.2 Battery replacement (modem battery)
During operation a check must be made from time to time of whether the modem battery
needs to be replaced. A display of the modem battery voltage (VbatM) is provided for this
in the DL210 under the list "Service". If this voltage is below 3.4V, the modem battery must
be replaced.
5.4.2.1 Carrying out battery replacement
1. Open up the front cover with the electronics and swivel downwards. The batteries
are then accessible in the bottom of the housing.
2. Check whether the size and identification number of the new battery match the
modem battery mounted in the bottom of the housing. Normally, the modem battery
has a white connecting cable.

When using two modem batteries it is essential to note that:
-
Both modem batteries must always be replaced together. Also the
retrospective replacement of a second battery is not permissible.
-
Both modem batteries must always be of the same type and from the same
batch (battery label: BMT week / year).
3. Pull off the existing modem battery or
batteries from the terminals X12 and X13
and plug on the new battery or batteries to
these terminals. The connectors are fitted
with polarity reversal protection and a
mech. interlock.
Important: Do not remove the device
battery.
4. Reclose the device (make sure that the cable is not pinched).
5. Check in the display that no message "3" is entered under "Status"!
6. Under "Interface" – "Network provider" (GSM.N, address: 2:775) press the key
combination "Enter" (press the keys and simultaneously). About 30 seconds
later the network provided should be displayed.
7. The voltage figure 3.6V should now be displayed under "Service" – "Modem battery
voltage" (VBatM, address: 4:410).
8. This successfully concludes the battery replacement.
