Battery level indicator
The individual segments of battery level display indicate a change in level of about IV.
By default the battery voltage indicator is displayed. If it is not displayed, press BATT/TAPE
key (34).
When the battery level is about 13V, the display will be as follows:

When the battery level drops below 10.5V, the transport will shut down. The battery indicator
will flash on the display as follows:

Note:
The indicator will also flash when the battery level is above 16V.
If the battery level drops below 9.5V, the PD-4 will shut down completely. This is to protect
the circuits from possible damage. To turn the power on again, first turn OFF the GEN switch
and the POWER switch, wait for about ten seconds, and then turn the POWER switch ON.
Reducing battery consumption
To reduce the drain on the PD-4's battery, try some of the following suggestions:
1}
Do not leave the PD-4 in PAUSE mode for long periods of time. In this mode, the drum
motor is running - rotating the record/playback heads.
2)
Only use the LCD light when necessary.
3)
Keep headphone or monitor speaker levels to a usable minimum.
4)
Whenever possible, connect the PD-4's outputs to input loads higher than 10kf2. 600n
input loads tend to drain the battery faster.
5)
Use of phantom powered microphones will put a greater load on the battery.
