Managing Power
This chapter describes how to power the receiver, charge the detachable batteries, and use an external power
source.
Turning On/Off the Receiver
To turn on the receiver, press and hold the power button for more than one second until the LEDs briefly flash.
When the receiver is turned on, the receiver’s channels initialize and begin tracking satellites from multiple
constellations (depending on the receiver’s supported features and current OAF).
To turn off the receiver, press and hold the power button for more than one and less than four seconds (until both
the STAT and the REC LEDs are off).
Powering the Receiver
The receiver is powered by the detachable, rechargeable batteries or an external power source connected to the
power port. If an external power source is connected, the receiver draws power from it over the battery.
Detachable External Batteries
Each detachable battery provides between 5 and 10 hours of operation, depending on the receiver mode.
To check the status of the detachable batteries, view the BATT LED or check the status using available Sokkia
software.
Charging the Batteries
The batteries are shipped from the factory without power. Fully charge the batteries before surveying. You can
use the power supply unit or the battery charging cradle to charge the batteries.
Power Supply Unit
The power supply unit (p/n 22-034101-01) charges the
external batteries when connected to a grounded outlet.
This unit converts the alternating current (AC) normally supplied from an electrical outlet to a direct current (DC)
used to charge the batteries and/or power the receiver.
You can connect the power supply unit to the charging cradle or directly to the receiver. See Figure 10 on page 17.
The power supply has the following specifications:
•
input voltage – between 100 and 240 V AC
•
frequency of input power – between 50 Hz and 60 Hz
•
output voltage – 12 V [email protected] A (30 W)
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.
he power supply unit is designed for indoor use only. Do not use in a damp or a wet environment. Do
not expose the power supply to rain or snow. It should only be used for charging the batteries. Do
not use as a power source during surveying.
