CLOCK BATTERY (RAM BATTERY)
The SMART Spectro 2 date/clock function is powered by a CR 1220 battery. This battery
should be replaced about every 8 years. If the date or clock function stops or if you receive
the message “Warning RAM Battery Low” you should replace the RAM battery as follows,
or contact the LaMotte Technical Service Department by phone at 1-800-344-3100, fax

Directions for opening the SMART Spectro 2 meter housing
1. Before proceeding, unplug the Spectro AC power supply.
2. Turn the meter over and use a long neck (4” shaft) Phillips head screw driver to
unscrew all 4 screws located in the recessed cavities. Note: do not remove the four
screws that secure the rubber “feet” to the bottom of the Spectro.
3. Holding the top and bottom together, carefully turn the meter over again. The screws
will fall out of the recessed cavity.
4. Carefully lift the top cover off . It is not necessary to disconnect any cables or wires.
CAUTION: Be careful. The electronic circuits are static sensitive.
DO NOT
touch the
electronic components. You do not need to touch the electronic components to replace
the RAM battery.
If you will be touching the electronic components for any other reason, you must wear a
grounding strap. If such a strap is not available then take every precaution possible to
ground yourself before and during any contact with the electronic components by holding
onto a grounded metal pipe or other grounded piece of metal. If this is not possible then at
least touch a grounded piece of metal just prior to handling any components or touching
the boards. Improper grounding can allow static buildup to short the components.
LaMotte Company is not responsible for any such damages.
Replacing the RAM Battery
1. The battery is a 3V coin battery on the top circuit board, about the size of a dime. It is
a model CR1220 or BR1225. Replace the battery with the same model type.
2. Unplug the battery by popping it out of its holder. A small insulated, fl at head screw
driver may be used to help remove the old battery.
3. Plug in the new battery with positive side facing up.
Assembly of the houseing top and bottom
1. Reassemble the spectro housing. When putting the top and bottom back together
be careful about the alignment of the metal panel on the back of the Spectro (lamp
access panel). There are slots for this panel in both the top and bottom part of the
housing.
2. Secure the top to the bottom using all 4 screws.
