3.2 Button Functions
The 5700 receiver has only two buttons: a Power button, represented
in this manual by , and a Data button, represented by .
Use  to switch the receiver on or off, and to perform data
management functions such as deleting files or resetting the receiver.
Use  to start or stop logging. This button is only effective when the
receiver is switched on and has completed any power-up and
initialization tasks.
Table 3.1 describes the main functions of the two buttons.
Note – The term “press” indicates that you should press the button
and release it immediately. The term “hold” indicates that you should
press the button and hold it down until the time indicated has elapsed.
