HiPerII Chapter 1
The receiver's power button is used to switch the receiver on or off. However, the receiver will
also automatically turn on if it detects activity on COM1. If you turn off the receiver while it is
logging data to the memory, it will save and close any open files before turning off. The
receiver does not support the use of schedules.
As an alternative to using the internal battery ( for example, if the internal battery is
discharged ), the receiver can also be powered using an external battery, following the
recommendations in this section.
If the external power input exceeds 18 VDC, it may damage the receiver.
When the external battery is discharged, the receiver will automatically switch to using the
internal battery. If the internal battery does not have sufficient charge ( or is not present ),
the receiver will turn off.
The receiver draws a small amount of power from the batteries while the receiver is off.
During long term storage, you should remove the battery.
If the internal battery and any external power input voltage are below minimum operating
parameters ( in other words, if the main battery is depleted, or external power is removed or
insufficient ), the receiver will initiate a power-down sequence. It will turn off and become
inactive. If this happens, you will not be able to turn the receiver on until you restore
sufficient power.
To return to normal operation, insert a charged battery or connect a valid external power input
to the receiver. When sufficient power is restored, the receiver will turn on if the power button
is pressed.
The receiver may also become inactive if the external power input is greater than the
power specified as acceptable for the receiver.

The receiver uses one rechargeable lithium-ion battery. It also contains an internal backup
battery, which maintains internal RTC. The backup battery is automatically charged from the
main battery.
The battery is capable of running for more than 8 hours on a single charge. ( static
