3. Optional. Connect the recorder to a remote source for turning the unit on/off.
By using the POWER ON/POWER OFF terminals, it is possible to turn on/off the
recorder externally. The POWER ON terminal turns power on or off (refer to Figure 8).
The POWER OFF terminal turns power off (refer to Figure 8). Turning the recorder on/off
also controls the output of the DC 5V OUT terminal (refer to Figure 8). Figure 9 shows
the schematic for the POWER ON/POWER OFF terminals.

4. Optional. Connect equipment to the CLOCK ADJ, REC, MODE OUT, and CALL OUT
terminals. Refer to Figure 10 for schematics of the input/output terminals.
The CLOCK ADJ input terminal is used for adjusting the clock. The input is active
when a ground or low voltage signal is applied. The input is non-active when the termi-
nal is open.
