The EPD is fitted with either a security type (tamper-proof) battery cap or a coin-
release battery cap, depending on customer requirements. The security type
battery cap helps to prevent unauthorised removal of the cap and requires a
special tool (see Section 2, Figure 2.2). During fitment of the battery cap the EPD
will begin its initialisation sequence. This is intentional and performs the function
of EPD start-up. The procedure to replace/insert an EPD battery is described in
Section 2.1.2. The initialisation/start-up sequence is described in Section 2.1.3.
