Mini Battery Replacement
The following instructions apply to the MiniOCS and MiniRCS.
1.
Disconnect power from the unit.
2. Remove ground screw (item #1) from back of unit.
3. Remove back cover (item #2) by carefully pressing in on one corner locking tab and lifting back
cover to disengage the locking tab. Repeat this for all four corners.
4. Unscrew the grounding spacer (item #3) using a ¼” Hex nut driver.
5. Gently lift up and remove the I/O board (item #4) from the three snap top fasteners on the CPU
board.
6. Once the CPU board is exposed locate the battery (item #5, U7). Remove the battery by prying
up slightly on each end until it lifts free. Dispose of the battery.
7.
Replace the battery with HE500BAT005 noting the polarity tab at one end of the battery. Use
care when replacing the battery that this tab is located in the right direction. Use only the authorized
battery part number.
8.
Reassemble the Mini unit by first replacing the I/O board then replacing the ¼” hex spacer. It is
recommended that Loctite
 222MS Threadlocker or an equivalent be applied to the male threads of item
#xx before reassembling. Line up the back cover with ground hole over the ground spacer and press back
in place. Make sure all four locking tabs of the back cover snap into place. Reconnect the ground wire.
Follow the instructions in the units’ manual for powering up the Mini and restoring it to operation.
