5.1 Battery Replacement
CAUTION
The installed computer board is equipped with a Lithium battery.
Danger of explosion if battery is incorrectly replaced. Replace only with battery of the
same or equivalent type (3-volt lithium coin cell battery).
•Do not attempt to recharge the battery.
•Do not disassemble, crush, puncture, short external contacts, or dispose of
in fire or water.
Compatible battery type: CR2032 (3 Volt lithium coin cell battery)
The battery is used for backing up the system time when the power supply is removed.
1. Turn off the computer properly through the operating system, then turn off any
external devices.
2. Disconnect the power supply from the power inlet and disconnect any external
devices.
3. Unmount the wall mount bracket product and locate the battery on the system main
board
4. Remove the battery from the holder (See figure 7)
5. Insert the new battery (See figure 7)
6. Reinstall the wall mount bracket
1. Removal: Insert screwdriver at right side and bend so that the battery
pops outs. Use only gentle force, otherwise the battery holder might be
damaged.
The use a plastic tool is preferred to avoid shorting the battery
2. Insertion: Align new battery to the left side of the holder and gently
press down on the right side of the battery until the battery snaps into
the holder.

5.2 PCI Express Mini Card
NOTICE
The PCI express mini card must not be inserted or removed when power is applied to the
system.
After inserting the mini card into the connector, it must be push down and locked with two M2,5
screws.
NOTICE
•The insertion depth of the screws that lock the PCI express mini card must not
exceed 3.2mm.
•Make sure that the diameter of the screw or the washer does not make contact
with components or traces on the mini card. Some cards have components very
near to the mounting holes.
The PCI express mini card socket does not support mSATA modules or other SATA
based storage modules.
5.3 Installing PCI-Cards
The PCI/PCIe slot versions of the emPC-CX+ series allows the use of add-on cards.
When installing PCI cards, please consider that the card must support 5VIO signalling.
Additionally the amount of current the emPC-CX+ system can provide to the slots is
limited.
A large amount of current drawn by the PCI card usually leads to a large amount of heat dissipated
inside the housing. This causes the system to overheat and a damage of the systems is possible. If
high power PCI cards are used a system fan is recommended. Contact the Janz Tec AG for further
information. Before installing a PCI card, please make sure that the system is turned off. To get
access to the PCI slot, the top cover must be removed. If you use a system with a built-in hard disk
drive, please be careful when opening the housing because the hard disk drive is mounted on the
backside of the top cover.
