Battery Backup for Full Power Reserve

Once the terminal back plate has been removed the 6 disposable AA

batteries should be inserted in the battery slots in the correct position

[polarity] (see Figure 7). These batteries are used to provide emergency

full power reserve for a limited time should AC power to the terminal be

interrupted. During this type of emergency the terminal will maintain full

function utilizing the power from these batteries to let employees in or

out. However, the amount of reserve power provided by these batteries

corresponds to the battery level as these batteries are disposable and

not charged by the MTX-15. Also, the battery life can be reduced by the

type of MTX-15 (i.e., the Ethernet MTX-15 requires the most power). The

function of these batteries should not be confused with the coin battery

function, which maintains power to the flash memory for setup and

transactions.

Note: Depleted AA batteries can leak which could lead to MTX-15

PCB corrosion and damage.
