Managing Power
••••••
This chapter describes how to power the receiver, charge the detachable batteries, and use an external power source.
The receiver will draw a small amount of power from the batteries when it is turned off. If the receiver is
placed in storage for a long period, such as a few months, the batteries may become fully discharged. You will
need to use an external power supply or recharge the batteries before use.
Managing Power
See “Specifications” on page 69 for more information on external power source requirements to power the receiver and charge
the internal batteries.
Power input greater than 18 VDC could damage the receiver.
Batteries
The battery compartment door provides access to the main battery. The receiver can also be powered using an external power
source.
Use one BDC70 rechargeable battery at a time to power the receiver.
The GRX2 also contains an internal backup battery, which maintains an internal RTC. The backup battery is automatically charged
from the main battery.
Managing Power
should be charged at least once every six months.
Table 3. Battery Storage Time
• The BDC70 uses the latest advances in high density lithium‐ion battery technology; however, like all batteries, it still
generates power using a chemical reaction and as a result, has a limited lifetime. Even when the battery is in storage and
not used for long periods, the battery capacity deteriorates with the passage of time. This may result in the operating
time of the battery shortening despite having been charged correctly. In this event, a new battery is required.

Managing Power
When the battery charge is low, the Available Power Bar changes from solid green to yellow to red and then blinking red,
depending on the remaining charge (see “Available Power Bar” on page 20). When the receiver is connected to an external
power source, the battery does not charge and becomes disabled from supplying power to the receiver.
To charge the battery, use the supplied charger. It takes approximately 4 hours to completely charge one battery and 8
hours to completely charge two batteries. The Li‐Ion batteries used in the battery packs should run at no less than 80%
capacity after 500 charging cycles. You do not need to drain the batteries before recharging.
The batteries are shipped from the factory with a partial charge. For maximum operating time, fully charge the
batteries before using the receiver.

Slots 1 and 2: The charger starts charging the battery mounted first. If two batteries are placed in the charger,
the battery in slot 1 is charged first, and then the battery in slot 2.
Charging lamp: The charging lamp is off when the charger is outside the charging temperature range or when
the battery is mounted incorrectly. If the lamp is still off after the charger falls within its charging temperature
range and the battery is mounted again, contact a local dealer.
Insufficient Power
If the batteries become fully discharged and an external power supply is not connected, the receiver will shut down and
automatically save recorded files. To avoid disruptions, check the Available Power Bar on the display panel for the battery charge
status. See “Available Power Bar” on page 20 for more information.
If the receiver shuts down due to insufficient power, the receiver and all communication ports become de‐activated.
To restore power to your receiver and turn it back on, do one or all of the following:
• Recharge the batteries.
• Make sure the power/serial cable is securely connected to the receiver’s port. Align the keyways (indicated with a red
dot) when connecting the power/serial cable to the receiver port.
• Connect the receiver to a different power source.
Power supplied to the receiver should match the specifications provided by Sokkia on the product. Failure to
comply with these specifications may damage the receiver.

This chapter provides general information about recording data, downloading it, and managing files.
Logging Rates
The receiver logs data on the SD/SDHC card that is inserted into the memory card slot. The amount of file space depends on the
size of the memory card being used. The GRX2 receiver can support memory cards of up to 32 GB capacity1. The amount of
memory used to log data depends on the logging rate. For more information about setting logging rate parameters, see the SRU
Reference Manual.
1. The maximum number of files is limited to 512. The receiver may take up to 50 seconds to check larger (8/16/32GB) SDHC cards when inserted into
the receiver. For 2 and 4 GB SD/SDHC cards, this external card check is completed instantly, allowing you to use it without any delay.
Collecting Data
The SD/SDHC card slots reside under the battery on the inside edge of the battery recess. The data that resides on the SD/SDHC
card can be accessed by removing the card and using an external SD/SDHC card reader or by using Sokkia software to download
the data from the card via GRX2’s serial port or Bluetooth connection. A secure digital card suitable for industrial use can be
purchased from a local Sokkia dealer. The SD/SDHC card is available in FAT16 or FAT32 format so that the removable SD/SDHC
card is suitable for copying data files directly to a computer. For recommendations about SD/SDHC cards, see “SD/SDHC Card
Recommendations” on page 88.
