1. If the MDP-25.0 is already installed, turn off all 12 volt loads connected to the output and disconnect the 12 volt input.
If unable to remove power first, make the DIP switch changes and then capture the changes by pressing the RESET button
once.
2. Access the DIP switches by removing two Phillips head srews securing the access plate located on the side of the unit
(left side if looking at the front of MDP).

3. To activate TMR feature: Move S3 group number 6 switch to the “ON” position (downwards).
4. Setting time delay: S3 group numbers 1 - 4 sets the delay time per Table 1 below when the MDP senses the vehicle
battery has fallen to 12 volts or less. The timer will reset or stop timing when the voltage sensed is 13.5 volts or greater,
example: engine alternator charging. See Table 1 below for time delay choices.
5. Note that the TMR feature is disabled if the ‘Ignition-IN’ pin (Pin 2 of the D-sub 9 pin connector on front panel, see
Figure 2) is connected to a voltage greater than 2 volts (i.e. +battery). Back-up function will still operate even when the
timer is activated, however; the load will still be removed after the TMR timer has timed out, even if the back-up battery is
able to support the output load.
