Power Management
If the GSR2600 is connected to a battery pack, it begins using the first battery
installed. When this voltage drops below 6.5 V DC, the battery is unusable, and
the GSR2600 will switch to the next available battery. Once battery reserves are
depleted, the GSR2600 shuts itself off.
Real-Time Clock
A real-time internal clock allows the GSR2600 to go into low-power “sleep mode”
between scheduled data-collection sessions. When the GSR2600 is on, this
clock is synchronized to GPS time of +1 second.
