Replacement Procedures
RFM 150 Instruction Manual 6–13
Replacing the Battery
1. Perform Instrument Disassembly on page 6–1. This includes
turning off the instrument and making sure there is no connection
to AC power, RF input, or Interface Port.
2. Referring to Figure 6–5, note the position of the battery pack.
There is a two-wire lead that connects the battery to the Back
Board circuit board assembly at J502. Note the position of the
lead, so that you can reinstall it in the same position. (Do not
wrap the lead around the post.) The jumper plug at J502 has a
small locking clip. Press the clip down to release the jumper, and
slide the jumper off the pins.
3. Remove the four screws that hold the battery cover in place, and
remove the battery cover. For reference, note how the battery
lead is positioned in the notch in the battery housing.
4. Turn the back cover upside down, place your hand under the
battery pack, then tap the back cover to remove the battery pack
from its housing and catch it with your hand. (Do not pull on the
battery lead.)
5. Install a new battery pack. Be sure to use only the battery
recommended for use with this product. Refer to the Replaceable
Mechanical Parts list in this manual for the part number. Ensure
that the cushioning foam is under the new battery and extends up
around the battery on both ends.
6. Place the lead from the new battery down through the notch in
the battery housing, and connect it to J502 on the Back Board
circuit board assembly. (The connector can only be installed
when the orientation is correct.) Be sure that the battery lead is
installed as shown in Figure 6–5, so that it will not be pinched
during instrument assembly. Check that the clip is locked on the
pins.
CAUTION.
A damaged battery lead can cause serious equipment
damage.
